一个基于Web的工作流管理系统

Internet/Intranet/WWW技术的日渐成熟以及资源、应用的日益丰富,为工作流管理系统的构造提供了一个理想的计算环境.在这种易于访问、无处不在的计算环境中,人们可以通过工作流管理系统将各种分布式的信息资源有效地集成、协调起来,以促使企业业务目标的高效实现.文章描述了一个基于Web而构造的通用工作流管理系统Wowww!(workflow on the world wide web),详细讨论了其体系结构的设计、工作流模型及过程实例的执行算法,并讨论了Wowww!为提高其可用性和灵活性而实现的工作

A Web-based Workflow Management System

As the Internet/Intranet/WWW technologies become more and more mature and web-based applications become richer and richer, the application developers are provided with an ideal computing environment to construct WfMSs (workflow management systems). Web-based WfMSs can help business goals to be achieved effectively by means of integrating various distributed resources in an easy to access environment. A web-based general purpose workflow management system named Wowww! is described in this paper, detailing its architecture, the workflow model and the algorithms used for workflow instance execution, the self-learning algorithm for automatic process definition generation, and the strategies to support synchronous cooperation.
