Research

Dr. Chen's interests cover a wide range of areas in discrete event systems modeling and simulation, Monte Carlo simulation, optimization, network management, and systems design under uncertainty. Recently, he has been engaged in the development of very efficient approaches for stochastic simulation and decision problems, and in their applications to air traffic systems, supply chain management, network design, logistics, manufacturing, scheduling, robot motion planning, stochastic equilibrium problems, and robust engineering design problems. Dr. Chen has developed very efficient simulation technologies, including Optimal Computing Budget Allocation (OCBA), which can dramatically improve simulation efficiency by orders of magnitude.

Selected Research Subjects
