Workflow process model and resource distribution analysis based on Petri net
基于Petri网的工作流过程模型及资源分布分析

According to the characteristics of workflow system,extended the Petri net model.This paper provided a new method of workflow modeling,i.e. extended ETdPN,presented formal definition of extended timed Petri net.Thereafter,this new method of time expression could be used to analyze four basic workflow models,i.e. the sequence,parallel,choice and iteration model. This paper provided a new calculation method of workflow response time by using queuing theory and stochastic Petri nets theory. The proposed method...
