摘　　要：为获得消息组件性能评价指标,基于离散时间休假排队模型Geom/G/1,建立了服务线程生命周期性能模型;采用嵌入Markov链方法,推导出具有单服务线程的消息驱动组件消息队列长度与响应时间概率分布;基于单线程循环调度与多态转移算法,实现了对多服务线程消息驱动组件的性能仿真.To acquire performance assessment of the magnet-driven component,based on discrete time vacation queue Geom/G/1,a life cycle performance model of service threads is created by analyzing embedded Markov chain and distributions of message response time and length of message queue are inferred.A simulation algorithm that is characterized by single thread schedule and multi-status shift is developed.Based on the algorithm,a performance simulator for message-driven component that support multiple service threads is designed.
