一种基于PDM的工作流管理服务框架的研究

Reseaching for PDM-Based Service Framework of Workflow Management

工作流管理系统用来支持组织内部或组织之间的业务建模及业务过程的协作运行．在工作流过程定义及工作流实倒 运行时,针对系统中的数据流处理,提出一个支撑工作流管理系统运行的服务框架,框架中的服务相对独立,同时又互相协作． 描述了应用背景和服务的意义并对设计原理进行形式化描述,采用接口表示服务间的协作关系,并给出一个可扩展的实现模 式,用该框架设计实现了一个嵌入式工作流管理系统KE/PDM-Workflow．

Workflow Management System （WfMS） is used to support the modeling and coordinated execution of business processes within an organization or across organization boundaries. Aiming at the processing of data flow when we define and excute the workflow proceses,we propose a service framework that supports the running of the workflow management system. In this framework, the services are independent relatively and coordinate each other. First we expatiate the various application background and the meaning of all kind of services. Second formularize the design principles of the services. Then we use the interfaces to define the coordination relationship of the services and propose an extensible implementing model. Finally we design and implement an embedded workflow management system that is called KE/PDM-workflow based on this framework.
