提出一种基于随机Petri网的协同服务事务处理模型与分析方法,分析企业协同服务中几个最具代表性的事务处理流程。以电子商务系统中的物流系统为例,分别对加入事务处理前后的流程应用模型进行等价化简,从而得到2类流程模型,并利用随机Petri网的性能评价方法,对比分析加入事务处理前后系统业务响应时间和吞吐量。
A transaction processing of collaborative service model and analysis based on Stochastic Petri Net(SPN) is put forward. The enterprise collaborative services in a number of the most representative transaction processing is analyzed. The logistics system of E-commerce systems is taken as example, based on SPN modeling, the equivalent simplification and performance evaluation are used. The original model and transaction processing model of system performance and response time is compared.
