Workflow Flexible Technology Research And Design

To acquire preponderance over global competition, enterprise must rapidly response the market's requirements, constantly adjust their organization mode and their business process. Workflow management is a tool to realize Computer Support Collaboration Work, it can realize the management of workflow entirely or partially automatically. It is convenient for reasonable disposition of personnel and resource, the supervision, examination of workflow to improve working efficiency.To make the workflow management system carry out the work to flow ,the change of logic according to the actual circumstance flexibly, to adapt the new changes in the process of enterprise running, to respond to the requirements of market, we are forced to improve the flexibility of workflow management system.The flexibility of workflow means, with the help of definition of workflow model and the engine of workflow, that workflow can adapt to the new changes of the enterprise business process without redefinition.This paper is about the researching of the technology of flexible workflow. Its content mainly is:First, we propose a workflow model FWFMS(Flexible Workflow Management System) which supported dynamic changes and set up a correctness restriction of workflow model. According to the scope in which the dynamic changes influence the workflow, we divide the workflow model into four sub-model: process model,resource model,organization model,information model. We show the flexibility of the workflow model by its four sub-model.Second, we propose the dynamic changes plan. This plan contains: dynamic changes of process instance and dynamic changes of process model. We discuss the" edition change" in dynamic changes of process model specially.At last,we use popular software technology to realize the flexible workflow management system and make a confirmation by a example.
