摘　　要：针对SOA实施过程中Web服务协商的需要,提出了一种Web服务协商协议.定义了通信原语,在服务提供者和服务消费者之间动态地协商服务信息,并采用Petri网模型对该协议进行了形式化描述,对Web服务组合进行建模及元素映射,给出了Petri网模型生成算法.In order to meet Web service negotiation requirements in SOA （Service- Oriented Architecture）, a service negotiation protocol is proposed to negotiate automatically quality of service budgets between possible service provider and service consumer. A Petri nets model is used to describe formally negotiation protocol. Based on Petri net theory, the forreal definition and graphic description were proposed for web services and their composition; the dement mapping process was also illustrated. Then an algorithm was proposed to construct the Petri net model for web services negotiation composition.
