基于Web服务的动态虚拟企业

On Web-Service-Based Dynamic Virtual Enterprise

由于 Web服务技术具有完好的封装性、松散的耦合、使用标准协议规范、高度可集成能力且是跨平台的和开放的 ,这些特性满足了构建动态虚拟企业的要求 ,因此必将成为动态虚拟企业今后发展的方向。本文提出了使用Web服务技术构建虚拟企业模型。给出了支持基于

Shorter Lifetime, loose coupling, dynamicall y changing partners, better scalability become new trends of Virtual enterprise. I n this kind of environment it is necessary to study methods for implementing dyn amic virtual enterprise which has these new characters. In this paper we present our vision of the Web-service-based dynamic virtual enterprise: a highly inte roperable, dynamical, service-oriented enterprise infrastructure for small busi nesses and large corporations. In this enterprise infrastructure, UDDI(Universal Description Discovery Integration) become the enterprise register center. Any s ervice provider can enable its business to be programmatically accessible on the Internet (it becomes a Web service) and registers their service to UDDI. Distri buted, heterogeneous partner can search dynamically accessible service by UDDI a nd interoperate with other partner using standard data exchange format XML(eXten sible Markup Language) and message interchange protocol SOAP(Simple Object Acces s Protocol ). We studied the life cycle of Web-service-based dynamic virtual e nterprise and point out three key technologies for its implementation: (1) dynam ic search service provider by UDDI; (2) Web service-based workflow; (3) Virtual enterprise portal.
