Performance Evaluation and Optimization of Complex Systems
Discrete Event Dynamic Systems (DEDS) are wide-existed systems in the world. In practice,
many man-made systems can be modeled as DEDS, such as manufacture system, communication
network, and transportation system. This kind of systems is driven by events and cannot be
described through differential equations. We can only evaluation the performance through
simulation. Thus, it is a practical and valuable research direction to combine the
simulation and optimization effectively. My current research is based on schedule problem in
manufacture system.
Stochastic Optimization
Optimization through simulation can be modeled into stochastic optimization. In other words,
the objective function and the constraints relate to some stochastic variables, which
furthermore can only be observed through simulation and the probability characteristic of
which is unknown. Prof. Xi-Ren CAO and Prof. Yu-Chi HO developed Perturbation Analysis (PA)
in 1980s, which helps to extract the gradient information from one simulation. Prof. Ho
developed Ordinal Optimization (OO) in 1990s, which helps to lessen the computation burden
in stochastic optimization through exponential convergence of the order and goal softening.
My current research efforts are mainly focused on the perturbation analysis and its
combination with Markov decision processes (MDP), event-based optimization, and schedule
problem in manufacture system.
