Q. Hu, hu@enga.bu.edu Prof. Pirooz Vakili vakili@enga.bu.edu Research focuses on complex manufacturing and production systems and the pursuit of an enterprise integration environment for concurrent production planning and control. Means used in this pursuit include: -hierarchical decomposition of complex manufacturing systems -development of state of the art dynamic decision support systems and algorithms including manufacturing flow control, scheduling, and performance evaluation, as well as their interoperation with legacy software such as MRP, CAM, and shop floor tracking. -development of flexible information system software -communication-network related issues -Flexible design with dynamic redesign/reengineering capabilities of a system of autonomous decision making agents interacting for the dual purpose of planning and operating a complex production facility. Key words: Enterprise Integration, Hierarchical Production Planning and Control, Reengineering of Production Management Process, Software Architecture for Concurrent Production Control REFERENCES Fu, M.C., and Hu, J.Q., "Addendum to Extensions and Generalizations of Smoothed Perturbation Analysis in a Generalized Semi-Markov Process Framework," to appear in IEEE Transactions on Automatic Control, August, 1995.
