虚拟企业中电子商务应用的工作流模型及实现

虚拟中企业中电子商务技术应用的一个关键点是实现要实现跨组织、多数据库、实时的数据集成和过程集成,基于角色和扩展的Petri网,设计了一个能够建立虚拟企业中电子商务应用的工作流模型,并给出了原型系统的体系结构,该模型在概念层上比较容易表示各伙伴企业在实现业务目标时的动态行为;在物理实现时比较容易基于分布对象结构实现对象的即插即用、互操作,为虚拟企业实现电子商务应用提供了新的思路。

A WORKFLOW MODEL AND ITS IMPLEMENTATION FOR E-COMMERCE APPLICATION IN VIRTUAL ENTERPRISES

One key to E-commerce applications in virtual enterprises is to realize real-time information integration as well as process integration cross organizations and among multi-databases. Based on the roles and the extended Petri-net, a workflow model is designed, that can be used to create E-commerce applications in virtual enterprises. The prototype system architecture is presented. In the concept level, the model is suited to present partners dynamic behaviors in the processes of realizing the business goals. And in the implementation level, the model is suited for objects to "plug and play" and interoperate based on the distributed object architecture. The result of the disscussion suggests a new concept for E-commerce applications in virtual enterprises.
