EDUCATION
Cornell University Ithaca, NY Ph.D. OPERATIONS RESEARCH 1990
Dissertation: "A New Approach to Production Planning, Scheduling, and Due-Date Quotation in Manufacturing Systems." Studied the mathematical structure of the schedule used in a cyclically scheduled manufacturing facility. Exploited this structure in developing a method for the calculation of operation start times, batch sizes, and projected completion time for a given demand. Developed an efficient algorithm based on Dantzig-Wolfe decomposition to solve the problem of finding the least cost combination of additional resources needed to meet the demand by a given due-date. Advisor: Professor John A. Muckstadt
Minors: Probability and Statistics, Business Administration (Operations Management)
Naval Postgraduate School Monterey, CA M.S. OPERATIONS RESEARCH 1980
