PDM环境下构件技术与工作流技术集成研究

摘要

In recent years ,it has already acquired a great deal of successful application in MIS by using the workflow technique and Component-Based Software Development(CBSD)technique ,but the integration of the both is lacked very much.It defines the related concept of workfiow technique and component technique based on workflow technique in PDM environment,puts forward an application integration frame of workflow based on component technique ,gives the realization relationship of component and workflow activity and also puts forward the model and detailed algorithm of workflow engine assembled component.The result shows that this integration frame can separate application logic and process logic and provide the agile assembly ability of business process.It is helpful to reorganize an enterprise business process ,raise the maintainability、reusability and flexibility of enterprise information system.%近年来,利用工作流技术、构件开发技术(CBSD)已在企业信息系统中获得大量的成功应用,而两者的有机集成在系统开发应用中还很缺乏.以工作流技术为基础,在PDM环境下,定义了工作流技术与构件技术的相关概念,提出了基于构件技术的工作流应用集成框架,给出了构件与工作流活动的实现对应关系,提出了工作流引擎组装构件的模型及详细算法.研究实例表明基于构件的工作流集成技术不仅能分离应用逻辑与过程逻辑,而且能提供业务流程的灵活定制能力,有利于企业进行业务流程重组,提高企业信息系统的的可维护性、可重用性和柔性.
