摘要
提出了一种基于随机Petri网的协同服务模型与分析方法,选择了企业协同服务中几个最具有代表性的流程,利用随机Petri对这些代表流程进行了建模以及模型简化和证明。然后,以电子商务系统中的物流系统为例,在随机Petri网模型建模的基础上应用模型等价化简和性能评价方法,对模型化简前后的系统性能和计算时间进行了对比分析。
A model and analysis method of collaborative services based on Stochastic Petri net were put forward,a collaborative enterprise service in several of the most representative process was selected. We used stochastic Petri net to model these processes. Then, we took the logistics system of e-commerce systems as example, based on stochastic Petri net modeling, used equivalent simplification, and performance evaluation and compared the original model and simplified model of system performance and computing time.
