事件驱动的工作流管理方法及执行引擎

Management Methods and Execution Engine of the Workflow based on Event Driven

随着经济的飞速发展,企业业务流程构成复杂、多变,而传统的工作流所建立的流程模型只能按照线性的路由执行,已不能满足现实需要。通过引入事件驱动机制,对事件进行建模,并采用事件的发布与订阅机制实现不同流程之间的事件关联,其后详细介绍了事件驱动的工作流系统实现原理。最后,采用工作流服务平台进行仿真和验证。

With the rapid development of economy, the business processes are complex and variable, but the traditional workfiow process model established is only in accordance with the linear routing implementation, which could not meet the practical needs. This paper introduces event-driven mechanism, defines event modeling and adopts event publish and subscribe mechanism for event＇s correlation between the different processes, with detailed descriptions of the principle of event driven Workflow system. Finally, the paper uses the work- flow platform for simulation and verification.
