The other four finalists chosen at the fall 2015 Capstone Expo were the \u003Cstrong\u003ERaceTrac\u003C\/strong\u003E team, which was the ISyE winner at the Expo (the first time the award has been given), and teams that worked with the \u003Cstrong\u003ECenters for Disease Control\u003C\/strong\u003E (CDC), \u003Cstrong\u003EEmory Surgical\u003C\/strong\u003E, and start-up company \u003Cstrong\u003EMonsieur\u003C\/strong\u003E.\u003C\/p\u003E\u003Cp\u003EEmory\u2019s Department of Radiology performs over 68,000 MRI procedures annually, making it one of the busiest MRI practices in the U.S. In order to improve \u003Cstrong\u003EEmory MRI\u2019s\u003C\/strong\u003E patient flow and patient experience, the Senior Design team designed and evaluated alternative scheduling strategies using a computer simulation model. The recommended strategy is expected to increase throughput by 1.55 patients per day, on average, thus generating an extra $470K in annual profits. Importantly, the recommended strategy is also expected to increase patient satisfaction: it decreases the average waiting time per patient by 2 minutes, primarily by reducing the longest waiting times.\u003C\/p\u003E\u003Cp\u003E\u201cWe at Emory are proud to have worked with the Georgia Tech ISyE Senior Design Emory Radiology MRI team. Their work will enhance our ability to drive forward value for patients and the health system concomitantly in the MRI radiology space,\u201d said Dr. Gregory J. Esper, the director of New Care Models at Emory Healthcare. \u201cThe team exhibited a tenacious desire to identify the true problem in MRI flow, and they implemented a test of change that has already shown operational improvement. Experiences with teams like this fuel the desire at Emory to continue our involvement in the Georgia Tech ISyE Capstone projects.\u201d\u003C\/p\u003E\u003Cp\u003ETeam members included \u003Cstrong\u003EMartin Restrepo\u003C\/strong\u003E, \u003Cstrong\u003EPaola Lopez Mantilla\u003C\/strong\u003E, \u003Cstrong\u003EAyda Sawaf\u003C\/strong\u003E, \u003Cstrong\u003EEmilio Jose Munoz Leone\u003C\/strong\u003E, \u003Cstrong\u003EArmida Mariana Arcaraz Vazquez\u003C\/strong\u003E, \u003Cstrong\u003EFelipe Martinez\u003C\/strong\u003E, and \u003Cstrong\u003EAlberto Nogueira Vazquez\u003C\/strong\u003E. They were advised by Professor\u003Cstrong\u003E Natashia Boland\u003C\/strong\u003E.\u003C\/p\u003E\u003Cp\u003EThe \u003Cstrong\u003ERaceTrac\u003C\/strong\u003E team introduced a new inventory management policy for RaceTrac Petroleum. RaceTrac, one of America\u2019s largest private companies, operates over 650 gas stations across the Southeast. Due to incentive misalignments with their 3PL fuel carriers, RaceTrac carries more inventory than necessary and experiences too many costly express or on-demand deliveries. The Senior Design team proposed the introduction of a new contract type that allows for better inventory management and delivery coordination. Expected benefits include an average inventory reduction of 40 percent and elimination of most on-demand deliveries, resulting in estimated savings of $500,000 per year.\u003C\/p\u003E\u003Cp\u003ETeam members included \u003Cstrong\u003EAnubhav Jain\u003C\/strong\u003E, \u003Cstrong\u003EMatthew Petersen\u003C\/strong\u003E, \u003Cstrong\u003EXiaoxin Yu\u003C\/strong\u003E, \u003Cstrong\u003EJustin Haffad\u003C\/strong\u003E, \u003Cstrong\u003EVignesh Ramesh\u003C\/strong\u003E, \u003Cstrong\u003EAnthony Robert Graziano\u003C\/strong\u003E, and \u003Cstrong\u003EJulie Deng\u003C\/strong\u003E.

Edenfield Chair and Professor \u003Cstrong\u003EMartin Savelsbergh\u003C\/strong\u003E.\u003C\/p\u003E\u003Cp\u003EThe \u003Cstrong\u003ECDC\u003C\/strong\u003E Senior Design team worked with the CDC\u2019s National HIV Epidemic Model and its corresponding calibration process. The model\u2019s purpose is to inform decision-making related to policy, research, and allocation of funding. Using a combination of parameter analysis, optimization formulation, and machine learning algorithms, the team delivered a comprehensive and flexible model calibration solution to the CDC. This implementation, which is packaged in a user-friendly interface, cuts calibration time from three months to as little as one day and saves the CDC at least $70,000 per year.\u003C\/p\u003E\u003Cp\u003ETeam members included \u003Cstrong\u003EAlison Burton\u003C\/strong\u003E, \u003Cstrong\u003EGregory Miller\u003C\/strong\u003E, \u003Cstrong\u003EElise Watson\u003C\/strong\u003E, \u003Cstrong\u003EMatthew Farkas\u003C\/strong\u003E, \u003Cstrong\u003ELaura Trube\u003C\/strong\u003E, \u003Cstrong\u003EMadison Rodenstine\u003C\/strong\u003E, \u003Cstrong\u003EMary Titus\u003C\/strong\u003E, and \u003Cstrong\u003EDaniel Brachey\u003C\/strong\u003E.

The \u003Cstrong\u003EEmory Surgical\u003C\/strong\u003E Senior Design team utilized linear regression to increase estimation accuracy and developed bin-packing based heuristics to create an improved scheduling policy. The two tools that were delivered will help Emory increase their surgery length estimation accuracy by 27% and reduce overtime by 54%. This translates to a $340,000 savings in overtime costs and $4.8 million in potential increased profits annually.\u003C\/p\u003E\u003Cp\u003ETeam members included \u003Cstrong\u003EAlivia Rumbaugh\u003C\/strong\u003E, \u003Cstrong\u003EMelissa Mondello\u003C\/strong\u003E, \u003Cstrong\u003EMichael Ehmann\u003C\/strong\u003E, \u003Cstrong\u003ERebecca Bishop\u003C\/strong\u003E, \u003Cstrong\u003ESarah Kiefer\u003C\/strong\u003E, \u003Cstrong\u003EMohit Jasani\u003C\/strong\u003E, \u003Cstrong\u003ENellie Wong\u003C\/strong\u003E, and \u003Cstrong\u003ELogan Moore\u003C\/strong\u003E.

The Monsieur Senior Design team designed a drink menu optimization that allows users to create custom menus based on drink demand and profitability, as well as an inventory control model that takes in historical demand data and adjusts that data throughout an event to produce optimal ingredient refill times.
