TITLE: Applications of Sensitivity Testing Methods to US Army TechnologiesABSTRACT: This presentation will discuss some applications of sensitivity testing to US Army products and systems, analytical approaches, and some common issues encountered in this unique approach to testing.   The US Army Armament Research, Development and Engineering Center is located at Picatinny Arsenal, in northern NJ.  The ARDEC strives to support the Army's efforts to ensure Soldier survivability and enhance platform and area protection by providing engineering, design and development support. This support is essential to the rapid delivery of critical technologies to our Warfighters.  ARDEC's Statistics Group's applied statisticians provide project consultation and support on test design and statistical analysis to ARDEC's nearly 3,000 engineers and scientists.  Much of this support focuses on systematically designed experiments (DOE).   Army technologies deal with a lot of destructive testing with binary response data, where efficient test methods are required.  There are a variety of test approaches tailored to these test problems and their unique test requirements.  One of the test approaches often used by the Statistics Group is fully adaptive sensitivity test methods, including the 3pod (three phase optimal design) recently developed by C. F. Jeff Wu.   This presentation will focus on the unique needs inherent to destructive sensitivity test using a number of ARDEC technology case-studies as a backdrop.  We will discuss approaches being used in test design, statistical analysis of the test data, and resulting reliability, safety, and performance predictions.  We will also highlight the need for future research in the area of sensitivity test methods to support DoD test activities.
