摘要： 电子商务服务的分布式模型中,服务供应链的建立过程可使用多种算法,针对广度优先算法,该文设计了一套形式化的过程原语对其进行描述,完整表达出整个服务供应链的建立过程。该文定义的过程原语适用于在同一个分布式模型中多个服务请求者同时对同一服务发起的服务供应链,最后用Petri网对具体模型中服务供应链的建立过程进行建模。

Abstract: In the distributed e-commerce service model, service supply chain(SSC) can adopt many algorithms to build. According to the rule with which user launches SSC in Web service, depth-fist expansion search is proposed. The set of primitive operations for the algorithm is designed, which describes every possible step in the complete process about SSC. Through the primitive operations, the dynamic presentation of SSC and relationship between service entities that coexist in the distributed system can be accomplished, and thus influence each other. An analytic model of Petri net for the process of SSC is presented.
