报告题目:动态排队网络的资源配置与优化

报告人:山东财经大学统计与数学学院戴洪帅教授

报告简介:Optimal staffing problems for dynamic queueing systems have been studied extensively. A common method for such problems is stationary analysis. However, only a “fixable” staffing decision can be made by using this method. At the same time, in some practical situations, a “flexible” staffing decision is more appropriate and can improve the quality of service efficiently. Motivated by this, in this talk, we propose a stochastic-stage stationary approximation to approximate such a dynamic system. Roughly speaking, firstly the control chart is applied to detect change points of the arrival rate . Secondly, based on these change points, the time interval is stochastically divided into some small subintervals, and then at each epoch, the corresponding stationary queueing system is used to approximate the dynamic queueing system. Finally the corresponding optimal staffing decision is made. The simulation and case study for call centers show that our method has excellent monitoring effect and can effectively improve the quality of service.
