摘　　要：用经典Petri网对Web服务组合建模,其令牌类型的单一性不利于对模型的理解.针对这种不足,提出了一种基于着色Petri网的建模方法,给出了Web服务网系统结构的静态和动态特性,而且还给出了一个用着色Petri网建模的实例.应用结果表明,利用着色Petri网建立的模型具有较强的解释性和扩展性.Modeling in Web service composition by the classical Petri net is not suitable for understanding the model because of the single kind of its token. To solve the deficiency, a method of modeling based on colored Petri net （CPN） is developed. Based on this method the system＇ s structure of Web service nets in both static and dynamic conditions is provided. Moreover an application instance of the model is presented based on colored Petri net. The application results show that the modeling method in CPN can enhance the explanatory power and scalability.
