基于Petri网的动态Web服务组合建模

Web Service Dynamic Composition Modeling Based on Petri Nets

基于广义随机Petri网,提出了一种动态Web服务组合建模的方法。利用广义随机Petri网(GSPN)以及OWL-S组合过程对Web服务组合过程构建动态组合模型,实现Web服务的动态组合。并通过一个实例证明该方法的可行性。与现有的方法相比,该方法可以更有效地描述动态Web服务组合。

This paper presents a method to compose Web service dynamically based on generalized stochastic Petri nets.At first,the generalized stochastic Petri nets（GSPN） and OWL-S composition process are used to model dynamic modeling of Web Service automatic Composition process,and then realize the Web service dynamic composition.Finally,the feasibility of this method is demonstrated though analysis of an example.Compared with existing methods,this method can describe Web service dynamic composition more effectively.
