Research

Dr. Chen's interests cover a wide range of areas in discrete event systems modeling and simulation, Monte Carlo simulation, optimization, network management, risk analysis, and decision making 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, semiconductor systems, supply chain management, network design, logistics, and robust design problems. Dr. Chen is the inventor of the novel simulation idea, called Optimal Computing Budget Allocation (OCBA), which can dramatically improve simulation efficiency by orders of magnitude. Sponsored by NAF, NASA and FAA, Dr. Chen has worked on several critical research issues in the analysis and management of US air traffic network with the Center for Air Transportation Systems Research.  For a list of recent funded projects, please click here.
