摘要
工作流管理系统是信息系统领域最重要的研究内容之一 ,设计工作流管理系统是一个非常复杂的过程 ,要完成许多艰巨的任务。文中重点讨论了工作流管理系统中同步关系的实现方法 ,提出采用扩充的逻辑表达式来协调和控制工作流之间的同步关系 ,并给出了一个具体的例子来说明如何使用该方法。与其它方法相比 ,扩充的逻辑表达式具有方法简单、描述能力强。
The development of the workflow management system(WfMS) is one of the most important areas of research in information system. The design of the WfMS is a very complicate process, needing to accomplish many difficult tasks. In this paper, We discuss an implementation of synchronous relationship in workflow management system, propose to adopt the enhanced logical expression(ELE) to coordinate and control the synchronous relationship among workflows and give an example to illustrate how to use this method. Compared with other methods, the ELE has the characteristics of simple, easy to describe synchronous relationship, easy for implementation, practical for developing WfMS, etc.
