【摘要】 工作流应用目前一个很大的瓶颈就是工作流管理系统在集成方法上没有统一的标准,很大程度上要受到外部应用的限制。现有的工作流系统需要提出一种独立于不同企业应用的集成框架。通过引入W eb服务及企业应用集成两项技术,提出有效支持W eb服务应用及其他异质异构企业应用的工作流扩展模型;介绍基于该扩展模型的工作流管理系统原型及其在某虚拟企业管理信息系统中的应用。更多还原

【Abstract】 Workflow systems now face a difficulty that most Workflow Management Systems (WfMS) only support few enterprises’ existing applications and this problem has been the supreme bottleneck. Without uniform standard of integration, deployments of WfMS must be limited by exterior applications. So bringing a new application-independent integration framework forward becomes an urgent affair of WfMS. This paper imports Web Service and Enterprise Application Integration (EAI) into the reference model of WfMC and introduces our extended workflow model which can support Web Service and other heterogeneous applications. A WfMS prototype based on the extended workflow model and its deployment into the Management Information System of a virtual enterprise are also presented.更多还原
