Dimensional Analysis and Its Applications in Statistics
Dennis K. J. Lin
University Distinguished Professor
Department of Statistics
The Pennsylvania State University


Abstract: Dimensional Analysis (DA) is a fundamental method in the engineering and physical sciences for analytically reducing the number of experimental variables prior to the experimentation.  The principle use of dimensional analysis is to reduce from a study of the dimensions of the variables on the form of any possible relationship between those variables.  The method is of great generality.  In this talk, an overview/introduction of DA will be first given.  A basic guideline for applying DA will be proposed, using examples for illustration.  Some initial ideas on using DA for Data Analysis and Data Collection will be discussed.  Future research issues will be proposed.

Calibration, Error, and Extrapolative Predictions with Computational Models
Dave Higdon
Scientist
Statistical Sciences Group
Los Alamos National Laboratory

Abstract: In the presence of relevant physical observations, one can usually calibrate a computer model, and even estimate systematic discrepancies of the model from reality.  Estimating and quantifying the uncertainty in this model discrepancy can lead to reliable predictions - so long as the prediction "is similar to" the available physical observations. Exactly how to define "similar" has proven difficult in many applications. Clearly it depends on how well the computational model captures the relevant physics in the system, as well as how portable the model discrepancy is in going from the available physical data to the prediction.  This talk will discuss these concepts using computational models ranging from simple to very complex.

Short Bio: Dr. Higdon is a scientist in the statistical sciences group at the Los Alamos National Laboratory, Los Alamos, NM. He served as the group leader from 2005-2010. His research interests are in inference from combining computer simulation models with data from physical experiments or observations; modeling non-standard dependence structure; spatial modeling; inverse problems; image modeling; multiscale models; Monte Carlo methods; and applications in environmental and physical sciences. He received the Jack Youden prize from ASQ in 2006. He has started the ASA interest group on uncertainty quantification in 2010 and has served in the editorial board of several statistical journals.

SPEAKER:  Daniel Mitchell

ABSTRACT:

Hedge fund contracts are generally characterized by a flat fee, a performance fee and what are
know as high-water-mark provisions. This paper describes and characterizes these contract
features and analyzes how they influence the hedge fund's risk choices. We model the hedge
fund's portfolio choice as a stochastic control problem with hybrid discrete and continuous controls. We develop a computational method to solve this class of problems and prove its convergence.

Some Examples of Regularized Matrix Decomposition

Jianhua Huang

Professor

Department of Statistics

Texas A&M University


Abstract: In this talk, I will review some of my recent works on regularized matrix decomposition. Depending on the application, the matrix in consideration can be a data matrix, a latent canonical parameter matrix of an exponential family distribution, or the regression coefficient matrix of a multivariate regression. I will use the penalized least squares or penalized maximum likelihood method as a common approach for these matrix decomposition problems. I will discuss use of various penalty functions for regularization purpose, including sparsity-inducing penalty, roughness penalty, and their combinations. Governed by the structure of the problem, the penalty can be designed for one-way or two-way regularization. I will illustrate the key ideas using some examples, including functional principal components analysis, biclustering, reconstruction of MEG/EEG source signals, and protein structure clustering using protein backbone angular distributions. This talk is based on joint works with Andreas Buja, Xin Gao, Seokho Lee, Mehdi Maadooliat, Haipeng Shen, Siva Tian, and Lan Zhou.

<![CDATA[Distinguished Scholar Seminar]]> 27187 Towards Physical Internet Enabled Interconnected Logistics

Benoit Montreuil
Canada Research Chair in Enterprise Engineering
Laval University, Québec, Canada

We have recently introduced the Physical Internet to enable an order-of-magnitude improvement of the worldwide economic, environmental and societal efficiency and sustainability of moving, deploying, realizing, supplying and using physical objects. The Physical Internet is an open global logistic system founded on physical, digital and operational interconnectivity enabled through encapsulation, interfaces and protocols.  Building on the Digital Internet metaphor, it aims to allow logistics, supply chain and transportation to evolve from the current integrated era, beyond the emerging collaborative era, towards an interconnected era.

In this presentation, we first overview the current global logistics efficiency and sustainability challenges, and describe the key concepts underpinning the Physical Internet and Interconnected Logistics. Then we proceed to describe the current international state of research on advancing their conceptualization; assessing their potentiality through analytical, optimization and simulation models; engineering their constituents, and validating their feasibility in the field.

Through the presentation, we put a particular emphasis on the research results and avenues most pertinent to the Coca-Cola Chair in Material Handling and Distribution, as highlighted by the following two examples. First, The Physical Internet enables a new generation of handling, transport and storage technologies adapted to exploiting designed-for-logistics set of smart modular containers, and induces a new generation of logistics facilities geared for open pooling and consolidation, fast throughput and seamless multimodality, while being environmentally and socially friendly. Second, a recent award-winning France-Switzerland-Canada project has assessed through a simulation experiment, based on real flow data from two leading French distributors and their top 100 suppliers, that Physical Internet enabled Interconnected Distribution can improve the overall logistics-induced cost of consumer-goods distribution by 30% and reduce the greenhouse gas emissions by 60%.

Inference and Experimental Planning for Lumen Degradation Data
Under A Wiener Diffusion Process

Dr. Yuhlong Lio
Professor
Department of Mathematical Sciences
University of South Dakota Vermillion, SD 57069


Abstract: This seminar presents investigations of the lumen degradation of light emitting diodes (LEDs) subject to stress loadings. Cumulative damage measurements are collected from a two-variable constant-stress accelerated degradation test (ADT). The underlying process for the data is a Wiener diffusion process with a drift which depends on the stress loadings. General statistical inferences on the parameters and percentiles of the LED lifetime distribution are presented. Approximate lower confidence bounds of the LED percentile lifetime are given using the Fisher information of the maximum-likelihood estimates and Bonferroni's inequality. This work establishes optimal strategies on the constant-stress ADT plan for a compromised decision between experiment budget and estimation precision. The study provides an algorithm to search the optimal strategy for the ADT. Finally, an example of LED tests is used to illustrate applications of the proposed methods.

Bio: Dr. Yuhlong Lio received Ph.D. in Statistics from University of South Carolina in 1987. Since then he has served as assistant professor, associate professor and professor in the Department of Mathematical Sciences, University of South Dakota.  Dr. Lio is an Associate Editor for the Journal of Statistical Computation and Simulation.  His research interest includes Kernel smooth quantile estimation, reliability, survival analysis and statistical quality control.

The Australian coal export industry is the largest in the world.  Australian coal exports play a significant role in supporting the Australian economy, and in meeting the world's need for coal.  Australia is the largest exporter of metallurgical coal in the world, and the second-largest exporter of thermal coal, with about 60% of world market share in the former and about 20% in the latter. These exports make up almost 15% of Australia's total export earnings.

 

The Hunter Valley coal region, exporting coal through the Port of Newcastle, is a major contributor to this economic powerhouse. It is the primary source of thermal coal exports in Australia. In 2008 Newcastle port's throughput was around 92 million tonnes, which constituted more than 10% of the world's total trade in thermal coal. The Port of Newcastle exports a greater volume of coal than any other port in the world.

 

Most of the coal mines in the Hunter Valley are open pit mines. The coal is mined and stored either at a railway siding located at the mine or at a coal loading facility used by several mines. The coal is then transported to one of the terminals at the Port of Newcastle, almost exclusively by rail. The coal is dumped and stacked at a terminal to form stockpiles. Coal from different mines with different characteristics is ``mixed'' in a stockpile to form a coal blend that meets the specifications of a customer. Once a vessel arrives at a berth at the terminal, the stockpiles with coal for the vessel are reclaimed and loaded onto the vessel. The vessel then transports the coal to its destination. The coordination of the logistics in the Hunter Valley is challenging as it is a complex system involving 14 producers operating 35 coal mines, 27 coal load points, 2 rail track owners, 4 above rail operators, 3 coal loading terminals with a total of 8 berths, and 9 vessel operators. Approximately 1700 vessels are loaded at the terminals in the Port of Newcastle each year.

 

In this talk, we discuss a number of optimization problems arising when trying to maximize the throughput of the Hunter Valley Coal Chain as well as a class of incremental network design problems inspired, in part, by capacity expansion problems encountered in the Hunter Valley Coal Chain.

<![CDATA[Seminar]]> 27187 TITLE: Features of the Finnish Innovation System

SPEAKER: Professor Tuomo Kassi

The story of Finland was a success story in the 20th century economically. Finland became particularly visible as a successful high technology country since the middle of 1980s. In that time the technology policy of the country became more intensive, as the public agency called The Center of Innovation and Development (TEKES) was established to support the R&D projects of companies and technology capability accumulation in the universities and research institutions. The innovation policy has the good consensus support of the whole population. The innovation policy and the innovation system have very much a cluster based structure. Many international indicators showed the policy working surprisingly well. Those positive signs were among others in innovativeness, growth competitiveness, quality of life, gender equality, security, education, health care, expectancy of life, environment. But latest in 2008 it turned out that many of these indicators were measuring wrong things.   

The innovation system does not make the promising start-up companies to grow large. The economic environment does not attract Finnish and international companies to invest in Finland. The innovation support policy does not hit the goal, as the clusters broke out and the companies work in international company networks.  The country should be now searching for a new paradigm and new guidelines for industrial, technology and innovation policy. How could the research help in this search?

Abstract: Recent technological advances in biomedical research, such as the next generation sequencing (NGS) technology, have opened more opportunities for scientific discovery of genetic information. The NGS technology is particularly useful in profiling a genome for the analysis of DNA copy number variants (CNVs).   CNVs that are more than 50 base pairs (bps) long are also sometimes referred to as structural changes or structural variants (SVs).  Cancer development, genetic disorders, and many other diseases are usually relevant to SVs on the genome.  

The short sequencing reads data resulting from NGS are massive and information rich.  How to retrieve information from reads of the tumor and reference samples for accurate SV detection has become a computational and statistical challenge.  Interestingly, detecting boundaries of SV regions on a chromosome or a genome can be viewed as a change point problem of detecting sequencing reads or reads ratio changes presented in the NGS data.  We provide statistical change point models to help detect SVs using the sequencing data.  We use a Bayesian approach to incorporate possible parameter changes in the underlying distribution of the sequencing data.  Simulation studies have shown the effectiveness of the methods.  The methods are applied to some publically available NGS datasets, and SV regions on breast tumor cell lines are successfully identified.

<![CDATA[Statistics Seminar]]> 27187 TITLE: Adaptive Hierarchical Stochastic Collocation Methods for High-Dimensional Approximation, Discontinuity Detection and Parameter Estimation

SPEAKER: Guannan Zhang

ABSTRACT:

Abstract: We will discuss an adaptive hierarchical stochastic collocation (AHSC) framework that addresses several challenges arising in uncertainty quantification (UQ) including: quantification of high-dimensional quantities of interest; high-dimensional discontinuity detection; and reducing computational complexity of parameter estimation. For high-dimensional approximation, we extended the conventional AHSC method by incorporating the wavelet basis into the sparse-grid framework. Second-generation wavelets are used constructed from a lifting scheme which allow us to preserve the framework of the multi-resolution analysis, compact support, as well as the necessary interpolatory and Riesz property of the hierarchical basis. For high-dimensional discontinuity detection, we developed a hyper-spherical stochastic collocation method for identifying jump discontinuities by incorporating a hyper-spherical coordinate system (HSCS) into the sparse-grid approximation framework. An approximate discontinuity surface is constructed directly in the hyper-spherical system with a greatly reduced number of sparse grid points compared to existing methods. For parameter estimation problems with computationally expense physical simulations, we incorporate the AHSC approach with high-order hierarchical basis into Bayesian inference framework to reduce computational complexity in MCMC sampling. A surrogate of the posterior probability density function (PPDF) is constructed using the AHSC methods. High-order local hierarchical polynomials (e.g. quadratic, cubic basis) are used to further improve the accuracy and cost of the surrogate. Moreover, to efficiently approximate PPDFs with multiple significant modes, we also incorporate optimization into our new approaches.

SPEAKER: Professor Oliver Rose

ABSTRACT:

For a customer-oriented semiconductor wafer fab, low volume products such as development lots or customer samples are often more critical than high volume products with regard to cycle time and delivery reliability because of due date commitment. In this study, a global rule combining WIP balance and due date control is developed for a wafer fab with both low and high volume products. The purpose is to resolve the following two issues. how to balance WIP of high volume products with the due date cost of low volume products; and how to make the trade-off between on-time delivery and WIP balance for the low volume products.

In the second part of the talk, a priority matrix table is introduced to assign priority to lots considering both due date and workload information with the objective to keep lots going through the fab at the right pace to maintain WIP balance. Besides that, a WIP calibration method is proposed to recover WIP balance following unpredictable events such as tool failure. The simulation results demonstrate that the proposed priority matrix table achieves a better WIP balance than FIFO (first in first out) and ODD (operation due date), and the WIP calibration method is able to correct for the WIP imbalance.

<![CDATA[Seminar]]> 27187 TITLE: A Simulation -Based Optimization Platform (SBOP) for discrete logistics systems with applications to workforce scheduling of assembly lines

SPEAKER: Professor Oliver Rose

ABSTRACT:

In this presentation, we focus on solution strategies for scheduling problems in complex assembly lines with workforce constraints. Typical products are airplanes, industrial machines and turbines which are produced by multi-skilled resources in small lots or which are even unique items. This type of production scheduling problem is known as a Multi-Mode Resource-Constrained Multi-Project Scheduling Problems (MMRCMPP) with Activity Splitting. It is a combinatorial problem which is NP-hard.

Existing approaches are far from optimal and provide very rough heuristic results. For our solution approach, we even increase the complexity of the model by using both internal and subcontracted workers with different skills. We use a simulation-based optimization approach to obtain solutions for real-world problems in short runtimes. To that end, we propose a heuristic method for developing production plans with minimized slack, balanced workforce with minimal staff and high resource utilization. As a first step towards a cost optimization we also show how a cost model to evaluate the total cost of production plans can be integrated to our approach. The cost function considers resource cost, opportunity cost (unused resources), subcontracting cost, bonus and penalty payments and assembly overhead cost. We show some solution details including computational results for several production scenarios and a reference implementation of our Simulation-Based Optimization Platform (SBOP).

<![CDATA[Statistics Seminar]]> 27187 TITLE: One-bit Matrix Completion

SPEAKER:  Mark Davenport

ABSTRACT:

In this talk I will describe a theory of matrix completion for the extreme case of noisy 1-bit observations. Instead of observing a subset of the real-valued entries of a matrix M, we obtain a small number of binary (1-bit) measurements generated according to a probability distribution determined by the real-valued entries of M. The central question I will discuss is whether or not it is possible to obtain an accurate estimate of M from this data. In general this would seem impossible, but we show that the maximum likelihood estimate under a suitable constraint returns an accurate estimate of M under certain natural conditions. If the log-likelihood is a concave function (e.g., the logistic or probit observation models), then we can obtain this estimate by optimizing a convex program.

<![CDATA[Statistics Seminar]]> 27187 TITLE:  Tolerance Limits for Binary Data Under  Logistic Regression

SPEAKER:  Thomas Mathew

ABSTRACT:

Tolerance limits computed using a  random sample capture a specified proportion or more of a population, with a given confidence level. In the talk, the computation of  tolerance limits will be discussed for binary data under the logistic regression model. The  data consist of n binary responses, where the  probability of a  positive response depends on covariates via the logistic regression function.  Upper tolerance limits are constructed for the  number of positive responses in m future trials for fixed as well as for varying levels of the covariates. The former provides point-wise upper  tolerance limits, and the latter provides  simultaneous upper tolerance limits. The upper tolerance limits are obtained from upper confidence limits for the probability of a  positive response. To compute the required upper confidence limits for the
logistic function, likelihood based asymptotic methods, small  sample asymptotics, as well as bootstrap  methods will be discussed and numerically compared. The problems have been motivated by an application of interest to the U.S. Army, dealing with the testing of ballistic vests for protecting soldiers from projectiles and shrapnel, where the success probability depends on covariates such  as the projectile velocity, size of the vest, etc. Such an application will be used to motivate and illustrate the tolerance limit problem.

The talk is based on joint work with Zachary Zimmer and DoHwan Park.

BIO: Thomas Mathew is Professor, Department of Mathematics and Statistics, University of Maryland, Baltimore County Campus. He received his PhD in statistics from the Indian Statistical Institute in 1983. His research interests include the topics of equivalence testing and statistical tolerance intervals.

<![CDATA[OR Colloquium]]> 27187 TITLE: Dual Methods for minimizing functions with bounded variation

SPEAKER:  Yuri Nesterov

ABSTRACT:

We propose a new approach for justifying complexity bounds for dual optimization methods. Dual problems often have very big or unbounded size of the optimal solutions. This makes impossible to apply to the complexity analysis of corresponding schemes the standard framework. In this talk we propose new methods, which can work with unbounded feasible sets. All these methods are primal-dual: they generate both primal and dual solutions with required accuracy/feasibility guarantees. This is a joint work with A. Gasnikov (IITP, Moscow)

<![CDATA[Statistics Seminar]]> 27187 TITLE:  Stochastic inference of dynamic system models: from single-molecule experiments
to statistical estimation

SPEAKER:  Samuel Kou

ABSTRACT:

Dynamic systems, often described by coupled differential equations, are used in modeling diverse behaviors in a wide variety of scientific disciplines. In this talk we will consider their assessment and calibration in light of experimental/observational data. For the assessment, we explore how the deterministic dynamic system models reconcile with stochastic observations, using recent single-molecule experiments on enzymatic reactions as an example, where the single-molecule data reveal clear departure from the classical
Michaelis-Menten model. For the calibration, we will propose a new inference method for the parameter estimation of dynamic systems. The new method employs Gaussian processes to mirror a dynamic system and offers large savings of computational time while still retains high estimation accuracy. Numerical examples will be used to illustrate the estimation method.

SPEAKER: Ching-Shui Cheng

ABSTRACT:

Some useful templates for implementing design key construction of factorial designs with simple block structures, in particular those for the construction of unblocked and blocked split-plot and strip-plot factorial designs will be presented. The traditional method of constructing such designs is to use some independent treatment factorial effects to partition the treatment combinations into blocks, rows, columns, etc. One advantage of the design key construction is that a set of independent generators and the constraints imposed by the structures of the experimental units are built in the template, which facilitates a systematic and simple construction of the design layout and eliminates the need to check some conditions for design eligibility when the traditional method is used.

SPEAKER: Dr. Stephen Wright

ABSTRACT:

Optimization tools are vital to data analysis and learning. The optimization perspective has provided valuable insights, and optimization formulations have led to practical algorithms with good theoretical properties. In turn, the rich collection of problems in learning and data analysis is providing fresh perspectives on optimization algorithms and is driving new fundamental research in the area. After a brief survey, we focus on several problems --- signal reconstruction, manifold learning, and regression/classification --- describing in each case recent research in which optimization algorithms have been developed and applied successfully.

Despite numerous initiatives to reduce inventory, inventory levels for most companies have remained the same or increased. This may be due to inventory being held in multiple forms across a company's supply chain together with multiple transfer of ownership. This is not well understood by stakeholders who need the skills to analyze the tradeoffs between inventory costs and customer service levels.

The webinar will discuss maintaining levels of inventory necessary to provide customer service while minimizing inventory resulting from poor supply chain management.

<![CDATA[OR Colloquium]]> 27187 TITLE: Bridging Stochastic and Dynamic Programming: A Unified Framework for Sequential Decision Problems

SPEAKER: Warren Powell

ABSTRACT:

Stochastic programming and dynamic programming have thrived in different communities, largely motivated by different applications. Dynamic programming has long been associated with small-scale applications, plagued by the well-known “curse of dimensionality.” Stochastic programming, on the other hand, has been presented as a “richer framework” that scales to large-scale applications. In this talk, I will argue that both of these are myths. I will present a perspective that puts stochastic programming, “dynamic programming” and stochastic search into a common framework where all sequential decision problems are dynamic programs which can be solved using one of four classes of policies. I will offer a formal definition of a state variable (widely overlooked or even avoided in our community), and use this not only to show that “stochastic programming” is actually a form of dynamic programming, but also to show how widely used algorithmic strategies based on scenario trees can be streamlined. Ultimately, I hope to help provide students with a simple, easy-to-follow template for modeling stochastic dynamic problems which mimics the powerful language of mathematical programming.

SPEAKER: Kunter Akbay

ABSTRACT:

A multi-disciplinary team of engineers and scientist at GE Global Research Center (GRC) has been focused on the global need for improving the efficiency and the safety of patient care in the hospitals.  The unique systems approach is based on the integration of information systems, sensor technologies, and advanced computing and decisoning analytics.  The key analytics include simulation modeling, optimization, computer vision, sensor analytics, artificial intelligence, and advance software system design. The system approach is focused on answering three fundamental questions concerning design and real-time operations:  1) is the healthcare delivery system designed for efficiency or should it be re-designed?  2) Is the system operating well? Are there any near term bottlenecks? If so, can they be avoided?  3) Are the key safety protocols followed during the actual care delivery?  This seminar will provide an overview of the unique system approach to the complex problem and demonstrate some of the Industrial Engineering and Operations Research prototypes currently being validated in hospitals for Hospital Operations Management decision support.

Bio:  Kunter Akbay is a Principal Engineer at the GE Global Research Center in Niskayuna, NY.  He currently leads the hospital capacity and safety research initiatives.  He has 30+ years of experience in robust and smart process design using simulation and optimization technologies.  Prior to joining GE, Kunter had a simulation consulting business and before that he was an Associate Professor at Marquette University directing the Industrial Engineering Program.  He has B.S., MS., and Ph.D. degrees in Industrial Engineering.

<![CDATA[Faculty Candidate Seminar]]> 27187 TITLE:  High-Dimensional Change-Point Detection

SPEAKER: Yao Xie

ABSTRACT:

 How do we quickly detect small solar flares in a large video stream generated by NASA satellites? How do we improve detection by efficient representation of high-dimensional data that is time-varying? Besides astronomical imaging, high-dimensional change-point detection also arises in many other applications including computer network intrusion detection, sensor networks, medical imaging, and epidemiology. In these problems, each dimension of the data is obtained by a sensor, and there are multiple sensors monitoring the emergence of a signal---an abrupt change in the distribution of the observations. The goal is to detect such a signal as soon as possible after it occurs, and make as few false alarms as possible. 

Two key challenges in high-dimensional change-point detection are 1) how to extract useful statistics, 2) how to find an efficient representation of the data. Many high-dimensional data exhibit low-dimensional structures such as sparsity, or the data may lie on a low-dimensional manifold. The approach I take is to exploit these low-dimensional structures in change-point detection. I will describe a mixture procedure that exploits sparsity, and MOUSSE, an online algorithm for tracking the evolving data manifold and extracts efficient statistics for change-point detection. If time permits, I will also describe some recent work on low complexity change-point detection algorithms based on dimension reduction.

<![CDATA[Statistics Seminar]]> 27187 TITLE:  Inference and Optimalities in Estimation of Gaussian Graphical Model

SPEAKER: Harrison Zhou

ABSTRACT:

Gaussian graphical model has a wide range of applications. The study of Gaussian graphical model had attracted a lot of attention recently. In this talk we consider a basic question: when is it possible to obtain statistical inference for estimation of Gaussian Graphical Model? A regression approach will be proposed to obtain asymptotically efficient estimation of each entry when the precision matrix is sufficient sparse. If the precision matrix is not sufficient sparse, i.e., the sparseness condition fails, a lower bound is established to show that it is on longer possible to achieve a parametric rate estimation of each entry by a construction of a subset of sparse precision matrices and Le Cam's Lemma.

If time permits, we apply the asymptotic normality result to do adaptive support recovery, to obtain adaptive rate-optimal estimation of the precision matrix under various matrix
l_q norms, and to do inference and estimation for a class of latent variable graphical models, without the need of the irrepresentable condition and the l_1 constraint of the precision matrix, which are commonly required in literature.

This is a joint work with Zhao Ren, Tingni Sun and Cun-Hui Zhang.

<![CDATA[Guest Speaker]]> 27187 TITLE: Game Theory: A Modern Approach to Multiagent Coordination

SPEAKER: James Marden

ABSTRACT:

The central goal in multiagent systems is to design local control laws for the individual agents to ensure that the emergent global behavior is desirable with respect to a given system level objective.  Game theory is beginning to emerge as a valuable set of tools for achieving this goal. A central component of this game theoretic approach is the assignment of utility functions to the individual agents. Here, the goal is to assign utility functions within an “admissible” design space such that the resulting game possesses desirable properties, e.g., existence and efficiency of pure Nash equiibria.  Our first set of results focuses on ensuring the existence of pure Nash equilibria for a class of separable resource allocation problems that can model a wide array of applications including facility location, routing, network formation, and coverage problems.  Within this class, we prove that weighted Shapley values completely characterize the space of utility functions that guarantee the existence of a pure Nash equilibrium.  That is, if a utility design cannot be represented as a weighted Shapley value, then there exists a game for which a pure Nash equilibrium does not exist.  One of the interesting consequences of this characterization is that guaranteeing the existence of a pure Nash equilibrium necessitates the use of a game structure termed “potential games”.  To conclude this talk, we will discuss some preliminary results pertaining to characterizing the efficiency of pure Nash equilibria for such resource allocation problems. Here, we provide an analysis of two utility/cost sharing methodologies: the Shapley value and marginal contribution.  Somewhat surprisingly, it turns out that the Shapley value provides better efficiency guarantees than the marginal contribution for a broad class of systems.  This result suggests that performing a distributed gradient ascent on the true system level objective functions, which can be viewed as a marginal contribution design, may lead to inefficiencies in the resulting system behavior.

<![CDATA[OR Colloquium]]> 27187 TITLE: Quadratic Programs with On-Off Constraints

SPEAKER:  Dr. Jeff Linderoth

ABSTRACT:

We study optimization problems that involve both quadratic functional relationships between decision variables and 0-1 indicator variables that turn on and off these relationships. Problems of this class occur in many areas, including statistics, financial engineering, and engineering design. After reviewing earlier work on a reformulation technique applicable to the case when the quadratic functions are separable, we discuss on-going research aimed at attacking the non-separable case. We introduce an important set to study in this context that generalizes both the BoxQP set, studied by Burer and Letchford, and the well-known Boolean Quadric Polytope. We discuss the relative importance of families of valid inequalities for this set, and we show how one important class can be separated in polynomial time if the dimension is fixed. We conclude with computational results to demonstrate the utility of these inequalities on practical portfolio optimization instances. This is joint work with Hongbo Dong.

<![CDATA[Faculty Candidate Seminar]]> 27187 TITLE: Joint Optimization of Sampling and Control for Failing Systems Under Partial Observations

SPEAKER: Michael J. Kim

ABSTRACT:

Stochastic control problems that arise in condition-based maintenance typically assume that information used for decision-making is obtained according to a pre-determined sampling schedule. In many real applications however, there is a high sampling cost associated with collecting such data. It is therefore of equal importance to determine when information should be collected as it is to decide how this information should be utilized for maintenance decision-making. This type of joint optimization has been a long-standing problem in the operations research and maintenance optimization literature, and very few results regarding the structure of the optimal sampling and maintenance policy have been published. In this talk, we formulate and analyze the joint optimization of sampling and maintenance decision-making in the partially observable Markov decision process (POMDP) framework. We prove the optimality of a policy that is characterized by three critical thresholds, which have practical interpretation and give new insight into the value of condition-based maintenance programs in life-cycle asset management.

SPEAKER: Dr. Zhigang Peng

ABSTRACT:

Seismology is a relatively new scientific field that uses seismic waves to study the interior of the Earth or other solid bodies and the seismic sources. Thanks to the recent advancement in sensing technology and data storage devices, seismic data are now routinely recorded in continuous mode. This has opened up many exciting new research directions in seismology, including identification of deep tectonic tremor along major plate-boundary faults around the world, and imaging of subsurface structures based on cross-correlations of continuous ambient noise signals. In this talk, I first summarize updated research results from these directions, followed by several case studies that utilize a waveform matching technique to identify new seismic events from continuous data. Finally, I will provide a list of future directions in earthquake seismology and possible areas for collaborations.

<![CDATA[Seminar]]> 27187 TITLE:  Cloud computing: survey of optimization problems

SPEAKER: Ilyas Iyoob

ABSTRACT:

The term ‘cloud’ is becoming increasingly popular in the IT world, and in spite of all the skepticism, a large number of early adopters are working with us to test and validate the feasibility of cloud computing.  The complexity of the cloud combined with the extensive amounts of data collected, causes it to be a very attractive candidate for stochastic modeling and optimization, but little has been done in this field because of (1) the immaturity in cloud technology, and (2) the lack of standardization.


In this talk, we first introduce cloud computing from an OR perspective, followed by a classification of optimization problems in this space using a supply chain analogy.  We list the different stochastic modeling and optimization problems to be solved by each echelon in the cloud IT supply chain: cloud providers, cloud consumers, and cloud brokers. Finally, we describe a case study from the State of Texas that shows that the true benefits of cloud computing can be acquired only through rigorous application of analytics and optimization to the planning and execution of the cloud.

<![CDATA[Guest Speaker]]> 27187 TITLE: Gradient-based Adaptive Stochastic Search

SPEAKER: Enlu Zhou

ABSTRACT:

Gradient-based adaptive stochastic search (GASS) is an algorithm for solving general optimization problems with little structure. GASS iteratively finds high quality solutions by randomly sampling candidate solutions from a parameterized distribution model over the solution space. The basic idea is to convert the original (possibly non-continuous, non-differentiable) problem into a differentiable optimization problem on the parameter space of the parameterized sampling distribution, and then use a direct gradient search method to find improved sampling distributions. Thus, GASS combines the robustness feature of stochastic search by considering a population of candidate solutions with the relative fast convergence speed of classical gradient methods. The convergence and converge rate properties of the algorithm are analyzed. The performance of the algorithm is illustrated on a number of benchmark problems and a resource allocation problem in communication networks.

<![CDATA[Manufacturing Brown Bag Seminar]]> 27187 TITLE: Innovation in Food and Poultry Processing

SPEAKER:  Doug Britton

ABSTRACT:

With the world population estimated to grow by 30% to 9.1 billion by the year 2050, and the realization that arable land is actually decreasing as a result, the old adage of “doing more with less” is a distinct reality when it comes to the world’s food production systems. And within this conundrum lies an opportunity for transformational innovation in a domain that has been around as long as life itself – Food! Agriculture and Food are not often the subject of traditional engineering or manufacturing educations, but given the challenges associated with feeding a growing world, the opportunities will fall in the collaborative spaces between the modern agricultural sciences and the core engineering disciplines. This talk will present the variety of research activities ongoing in the Agricultural Technology Research Program at Georgia Tech. We will also discuss the unique challenges of meeting food safety requirements, the manipulating food and poultry products that are not uniform, as well as some of the environmental impact considerations for a modern food manufacturing facility.  Finally, we will define and discuss transformational innovation with respect to the food and agriculture space, and talk about the opportunities for reinventing the animal agriculture production and processing facilities of the future.  What should they look like, and how do we get there?

SPEAKER: Todd McDevitt

ABSTRACT:

The McDevitt Laboratory for the Engineering of Stem Cell Technologies is focused on the development and application of engineering principles to translate the potential of stem cells into viable regenerative therapies and in vitro diagnostics. Biomaterials-based approaches are used to engineer the microenvironment of stem cells in order to improve the efficiency and homogeneity of directed stem cell differentiation strategies.

In addition, the McDevitt laboratory’s research focuses on development of novel regenerative molecular therapies from natural biomaterials produced by stem cells. The combination of directed stem cell differentiation and development of stem cell-derived biomaterials is expected to yield fresh insights into stem cell biology, facilitate new regenerative therapies and create novel cell diagnostic platforms. The McDevitt laboratory research is supported by funding from the National Institutes of Health, National Science Foundation, American Heart Association and the Georgia Research Alliance, among others.

McDevitt was named the 2010 Society for Biomaterials Young Investigator from the Society of Biomaterials. He was appointed as a Petit Faculty Fellow in the Institute for Bioengineering and Bioscience in September 2009 and named the Director of the new Stem Cell Engineering Center at Georgia Tech, which launched in 2010. It is the first center of its kind in the United States will bring together expertise from different engineering disciplines to address key technical challenges that currently limit the translation of stem cells and to innovate new technologies that will enhance basic stem cell research.

SPEAKER: Stephen Wright

 

ABSTRACT:

Problems of packing shapes with maximal density, sometimes into a container of restricted size, are classical in discrete mathematics. We describe here the problem of packing a given set of ellipsoids of different sizes into a finite container, in a way that allows overlap but that minimizes the maximum overlap between adjacent ellipsoids. We describe a bilevel optimization algorithm for finding local solutions of this problem, both the general case and the simpler special case in which the ellipsoids are spheres. Tools from conic optimization, especially semidefinite programming, are key to the algorithm. Finally, we describe the motivating application - chromosome arrangement in cell nuclei - and compare the computational results obtained with this approach to experimental observations.

This talk represents joint work with Caroline Uhler (IST Austria)

<![CDATA[OR Colloquium]]> 27187 TITLE: On the Structure of Reduced Kernel Lattice Bases

SPEAKER: Karen Aardal

ABSTRACT:

Lattice-based reformulation techniques have been used successfully both theoretically and computationally. One such reformulation is obtained from the lattice $L_0=\{x\in Z^n\mid Ax = 0\}$. Some of the hard instances in the literature that have been successfully tackled by lattice-based techniques, such as market split and certain classes of knapsack instances, have randomly generated input $A$. These instances have been posed to stimulate algorithmic research. Since the considered instances are very hard even in low dimension, less experience is available for larger instances. Recently we have studied larger instances and observed that the LLL-reduced basis of $L_0$ has a specific sparse structure. In particular, this translates into a map in which some of the original variables get a ``rich'' translation into a new variable space, whereas some variables are only substituted in the new space. If an original variable is important in the sense of branching or cutting planes, this variable should be translated in a non-trivial way. In this paper we partially explain the obtained structure of the LLL-reduced basis in the case that the input matrix $A$ consists of one row $a$. Since the input is randomly generated our analysis will be probabilistic. The key ingredient is a bound on the probability that the LLL algorithm will interchange two subsequent basis vectors. It is worth noticing that computational experiments indicate that the results of this analysis seem to apply in the same way also in the general case that $A$ consists of multiple rows. Our analysis has yet to be extended to this general case. Along with our analysis we also present some computational indications that illustrate that the probabilistic analysis conforms well with the practical behavior. This is joint work with Frederik von Heymann.

<![CDATA[Faculty Candidate Seminar]]> 27187 TITLE: New Approximations and Algorithms for Stabilizing Time Varying Queues

SPEAKER: Jamol Pender ABSTRACT: 

We develop two new algorithms for stabilizing time varying queues delay probabilities by expanding the queue length in terms of Hermite polynomials.  The first algorithm uses the mean and variance of the queue length.  The second algorithm uses the mean, variance, and skewness of the queue length.  We show that the skewness helps in stabilizing the queue length at positive target values, especially when the queue is critically loaded.  We illustrate through several simulation studies the added benefit of using higher moments of the queue length distribution.

<![CDATA[Faculty Candidate Seminar]]> 27187 TITLE: Filtered Likelihood for Point Processes and Applications in Credit Risk

SPEAKER: Gustavo Schwenkler

ABSTRACT:

We develop likelihood estimators of the parameters of a marked point process and of incompletely observed explanatory factors that influence the arrival intensity and mark distribution. We provide conditions guaranteeing consistency and asymptotic normality as the sample period grows. We also establish an approximation to the likelihood and analyze the convergence and asymptotic properties of the associated estimators. We apply these estimators in an empirical study of the sources of corporate default clustering in the United States. Both frailty and contagion, by which the default by one firm has a direct impact on the health of other firms, are significant sources of default clustering between 1970 and 2010. These findings have important implications for risk management and the regulation of financial markets.

SPEAKER:  Otis Jennings

ABSTRACT:

Consider a firm whose heterogeneous customer base is sensitive to delays and has demands that exceed the firm’s currently unadjustable processing capacity. One example is an urban emergency department; another is an airport's landing strip during extended intervals of inclement weather. We model such settings as multiclass, overloaded queueing systems with customer abandonment. In such settings, quality of service (QoS) – and indeed whether service takes place at all – is highly dependent upon the order in which customers are processed. We consider two service disciplines. Under FIFO, whereby sufficiently patient customers are served in the order of their arrival, customers receive approximately the same QoS, measured in terms of delay until service initiation, regardless of customer type. We also consider Generalized Round Robin, a family of policies that allows the scheduler to provide differentiated QoS across customer types. This latter policy can be used, for example, to ensure high levels of service for critical customer segments, such as high acuity patients, while not neglecting other segments entirely.

<![CDATA[Statistics Seminar]]> 27187 Statistics (Student) Seminar

SPEAKER:  Matthias H.Y. Tan

ABSTRACT:

Although traditional quality improvement methods have been successfully applied in numerous contexts, they are not applicable to many modern manufacturing systems. Two recent manufacturing trends that pose significant challenges to the quality engineering community are production of small batches of high value products and the use of computer simulations for product design. This talk consists of two parts.

In the first part, I will present generalized selective assembly, which is a quality improvement method for small batches of high value products. Selective assembly has traditionally been used to achieve tight specifications on the clearance of two mating parts. We develop a generalized version of selective assembly, called GSA, for improving the quality of assemblies with any number of components and any known assembly response function. Two variants of GSA are introduced: direct selective assembly and fixed bin selective assembly.

In the second part, I will present a statistical methodology for robust design with computer experiments. Gaussian process (GP) models are widely employed in computer experiments to model quality characteristics as functions of control and noise factors. These models enable the average loss to be estimated without time-consuming simulations. However, robust design optimization performed as if the GP predictor were the true response function can give misleading results. We propose expected quadratic loss criteria that take into account uncertainty about the true function, and methods based on the Lugannani-Rice saddlepoint approximation for constructing accurate credible intervals for the average quadratic loss.

TITLE: Non-stationary and non-Gaussian surrogate models

SPEAKER: Rui Tuo (visiting Dr. Jeff Wu)

ABSTRACT:

Emulators are central in the modeling of computer experiments. As the development of the computational techniques, we are able to simulate complex physical systems more accurately. Existing methods, specifically the stationary Gaussian process models, may be inadequate to meet the demands of modern computer simulations when the computer code has tunable precision or the response surface is highly fluctuated. This talk consists of two parts.

In the first part, I consider deterministic computer experiments with real-valued tuning parameters which determine the accuracy of the numerical algorithm. A prominent example is finite element analysis with its mesh density as the tuning parameter. The aim is to integrate computer outputs with different tuning parameters. Novel non-stationary Gaussian process models are proposed to establish a framework consistent with the results in numerical analysis. Numerical studies show the advantages of the proposed method over existing methods. The methodology is illustrated with a problem in casting simulation.

In the second part, I discuss the conditional inference for ?-stable processes. We introduce a new class of ?-stable processes. The finite dimensional distributions of these stochastic processes can be represented using independent stable random variables. This representation allows for Bayesian inference for the proposed statistical model. We can obtain the posterior distributions for the untried points as well as the model parameters through an MCMC algorithm. The computation for the representation requires some geometrical information given by the design points. We propose an efficient algorithm to solve this computational geometry problem. Two examples are given to illustrate the proposed method and its potential advantages.

<![CDATA[Statistics Seminar]]> 27187 TITLE: Nonparametric Maximum Likelihood Approach to Multiple Change-Point Problems

SPEAKER: Changliang Zou (visiting Dr. Jeff Wu)

ABSTRACT:

In multiple change-point problems, different data segments follow different distributions where changes may be in the mean, scale or the entire distribution from one segment to another. Without the need to know the number of change-points in advance, in this talk I will introduce a nonparametric maximum likelihood approach to detecting multiple change-points. Our method does not impose any parametric assumption on the underlying distributions of the data
sequence, which is thus suitable for detection of any changes in the distributions. The number of change-points is determined by the Bayesian information criterion and the locations of the
change-points can be estimated by using the dynamic programming algorithm and further taking advantage of the intrinsic order structure of the likelihood function. Under some mild conditions, we show that the new method provides consistent estimation for both the
locations and magnitudes of the change-points with a rate, the square of log n. We also suggest a pre-screening procedure which is capable of excluding most of the irrelevant points. Simulation studies show that the proposed method has outstanding performance of
identifying multiple change-points in terms of estimation accuracy and computation time compared with existing methods. The new methodology is illustrated with two real data examples.

<![CDATA[ISyE Guest Speaker]]> 27187 TITLE: Dynamic Programming Approximations for Deterministic and Stochastic Routing Problems

SPEAKER: Dr. Alejandro Toriello

ABSTRACT:

We discuss the application of approximate dynamic programming techniques to several versions of the traveling salesman problem (TSP), with the goal of obtaining tractable lower bounds and high-quality solutions. The first half of the talk focuses on deterministic problems, including a new family of polyhedral lower bounds for the TSP and heuristic techniques that combine ideas from integer and dynamic programming. The second half extends our approach to stochastic models in which information is revealed dynamically; the motivating application is real-time vehicle routing. For a dynamic TSP with stochastic arc costs, we discuss how our bounding techniques extend, when they are efficiently solvable, and how to derive policies from them with performance guarantees and good empirical results.

<![CDATA[Faculty Candidate Seminar]]> 27187 TITLE: Principles of Design for Computer Experiments and Non-Communicable Disease in Pakistan

SPEAKER: Dr. Ben Haaland

ABSTRACT:

This talk will will consist of two parts as follows.

Simulations are used to study real systems for which real experimentation is not feasible. In the usual situation where runs of the simulation take a non-negligible amount of time and
computing, experimental design is extremely important in gaining high quality information from simulations. Principles of experimental design will be proposed and justified which ensure
high numeric accuracy, high nominal accuracy, and accurate parameter estimates for deterministic simulations. Specific situations addressed include non-stationarity, effect sparsity, non-trivial functional ANOVAs, and simplified functional representations, as well as the worst case scenario where the unknown function or mean function is highly non-linear with no low-dimensional representation.

Non-communicable disease (NCD), such as cardiovascular disease, cancer, and respiratory disease, have become the major cause of mortality in Pakistan. Estimates for 2010 and projections for 2025 of cause-specific mortality are presented along with estimates and
projections of deaths attributable to several important risk factors, such as tobacco use and hypertension, and deaths avertable through feasible interventions. We project that Pakistan can reduce NCD deaths by 20% in 2025 by implementing largely cost-neutral interventions.

<![CDATA[OR Colloquium]]> 27187 TITLE:  Fabrication-Adaptive Optimization and Its Application to Photonic Crystal Design

SPEAKER: Robert M. Freund

ABSTRACT:

It is often the case that computed solutions of many optimization problems cannot be implemented directly (irrespective of data accuracy) due to either (i) technological limitations (physical tolerances of machines or processes), (ii) the deliberate simplification of a model to keep it tractable (ignoring certain types of constraints that pose computational difficulties), and/or (iii) human factors (getting people to "do" x). Motivated by these observations, we present a modeling paradigm called "fabrication-adaptive optimization" for treating issues of implementation/fabrication, develop computationally-focused theory and algorithms, and produce computational results for incorporating considerations of implementation/fabrication into constrained optimization problems that arise in application settings. The proposed fabrication-adaptive optimization framework stems from the robust regularization of a function (Lewis 2002). We show how to do computation with fabrication-adaptive optimization in spite of challenges of non-convexity, and we apply our methodology to compute fabricable designs of two-dimensional photonic crystals with a variety of prescribed features. This is joint work with Abby Men, Jaime Peraire, Joel Saa-Seoane, and Ngoc C. Nguyen.

<![CDATA[SIAC Seminar]]> 27187 TITLE:  Funding Opportunities at the National Science Foundation in Manufacturing and Service Enterprise Systems

SPEAKER: Dr. Edwin Romeijn

ABSTRACT:

The Manufacturing and Service Enterprise Systems programs at NSF support research on strategic decision making, design, planning, and operation of manufacturing and service enterprises, respectively. Topics of interest include new models as well as analytical and computational tools for optimal planning, monitoring, control, and scheduling of operations in manufacturing and service enterprises that offer the prospect of implementable solutions. In this talk we will provide an overview of the two programs and describe particular focus areas as well as new research directions. In addition, we will discuss characteristics of successful proposals. Finally, we will address related programs and new initiatives at NSF that can provide funding for research in these areas.

The conference, which was initiated and organized by the Georgia Tech Health and Humanitarian Logistics Center since 2009, will be hosted by the Malaysia Institute for Supply Chain Innovation (MISI), a member of the MIT Global SCALE Network. The mission of the conference is to stimulate innovation and build capacity to manage humanitarian supply chains around the world. It brings together high level speakers from across the health and humanitarian sectors, including non-governmental organizations (NGOs), industry, government, etc.

The conference, now in its fifth year, is being held for the first time in Asia, where humanitarian response is especially critical. In 2011, Asia accounted for 86.3% of reported disaster victims worldwide.5 In addition, Malaysia is the hub for humanitarian logistics in Asia, hosting key facilities such as the United Nations Humanitarian Response Depot (UNHRD) and the Red Cross (IFRC) Regional Logistics Unit. Activities will encourage discourse among participants through plenary panels, interactive workshops, educational workshops, innovation posters and facility tours. Discussions will focus on the role of logistics in areas such as disaster response, health systems and food security as well as highlight the unique logistical challenges for humanitarian response in Asia. Ideas will be shared around emerging themes such as extending the reach of specialized nutrition products, exploring the role of social media and big data during crises, and examining the unique challenges for logistics in urban settings. You are welcome to email your ideas for panel themes, workshop topics, and potential speakers/facilitators to humlog2013@mit.edu or humlogconf@gatech.edu.

<![CDATA[Faculty Candidate Seminar]]> 27187 TITLE: Incomplete Information and Large Dimensionality in Decision Making

SPEAKER: Marco Molinaro

ABSTRACT:

This talk explores from different perspectives two main sources of difficulty in decision making: incomplete information and large dimensionality. In the first part, I will talk about optimization under uncertainty, more specifically resource allocation with item uncertainty. I will focus on the Online Packing IP model, where columns of the IP (i.e. items) come one-by-one in random order. This, and related models, have wide application in revenue management, e.g. airline booking and online advertisement allocation. Combining ideas from learning theory and geometric insights, we provide a strategy that is able to better cope with uncertainty and the first with guarantees that do not degrade as the number of items increases.

In the second part of the talk, I will address other perspectives on decision making. I will briefly discuss sublinear algorithms, which tradeoff the amount of information used to perform a computational task and the quality of the solution obtained. These are crucial in an increasing number of applications that involve massive data, ranging from biology to network analysis. Finally, I will discuss some of my work on Integer Programming, a classical tool for dealing with large decision spaces of combinatorial problems. Here, I will highlight our advances on the construction and analysis of cutting planes, a crucial piece of solving Integer Programs in practice, where we (partially) resolve several questions raised in the literature.
