  摘要:  

  We analyze a tiered airport security checkpoint at an international airport. In such a system, passengers can be classified into three categories based on the security intelligence. A two-dimensional Markov process and a Markov modulated Poisson process (MMPP) are utilized to model this type inspection systems. We first develop the formulas for the performance evaluation under a given passenger allocation policy with conditional capacity sharing in the tiered security-check system. Due to the complexity of the system and the multiple decision variables, a near-optimum inspection policy is determined by the simulated annealing method.  By comparing the proposed system with the two conventional security-check systems (non-tiered and tiered without capacity sharing), we find that the tiered system with conditional capacity sharing could improve the customer service without compromising the security quality.

  This is a joint on-going research project with Paul Hsing Luh and P.K. Huang of National Chengchi University.

 

  摘要:  

  Professor George Zhang holds a joint appointment between College of Business and Economics (Department of Decision Sciences) at Western Washington University and Beedie School of Business (Management Sciences) at Simon Fraser University. He received a BSc degree in computer science, an M.A.in economics from Nankai University, an MBA from Schulich School of Business at York University, and a Ph.D from the University of Waterloo.

  Professor Zhang's research interests include queueing theory, stochastic programming, and probability models in reliability, and operations and service management. Currently, he is particularly interested in the quantitative and economic analysis of the congestion problems in urban/mass transportation networks, health care systems, and public service systems with both customer service quality and security concerns. His publications have appeared in journals such as Management Science, Operations Research, Manufacturing & Service Operations Management, Production and Operations Management, Queueing Systems, Journal of Applied Probability and many other international journals in operations research and applied probability.

  Co-authored with N. Tian, his research monograph entitled Vacation Queueing Models-Theory and Applications has been published in 2006 by Springer Science. This is the first book that discusses both single and multiple server queueing systems with vacations. Professor Zhang is an associate editor of INFOR and is on the editorial board of several international journals
