摘要: 为估计串联服务系统中业务实例在特定负载及负载动态变化条件下的完成时间,提出了使用Monte Carlo仿真求解的方法。分析了对该问题进行数学求解的不可行性;根据问题特征,给出了业务实例排队系统的Monte Carlo仿真体系结构,设计了串联排队网络仿真软件,并对业务实例在特定负载下的完成时间进行了大量仿真。结果表明,Monte Carlo法可较快速地逼近业务实例的完成时间。

Abstract: To estimate completion time under specific load and dynamic load for business process instances in tandem service system, an approach based on Monte Carlo simulation was proposed. Infeasibility of solving the problem by mathematical analysis was demonstrated, and a Monte Carlo simulation system structure for tandem queue network was given according to the problem feature. Tandem queue network simulation software was designed to compute completion time for business process instances under specific load. Simulation results showed that Monte Carlo simulation could approximate completion time of business process instances rapidly.
