Designing And Realization Of Approval System Based On Flexible Workflow

In the process of manufacturing enterprise informatization, there is no technique can replace the workflow. It can realize the non-paper transfer of the document, information,data and so on and improve the efficiency of the manufacturing enterprise, and save the resource. The flow definition in traditional should define all the details, but It's hard to define all the details of the flow, Manufacturing enterprise have a strong demand for flexible workflow, The demand push the research of the flexible workflow.In this paper mainly research on the designing, realization and apply of the flexible workflow. The main content of this paper as below:Firstly, introduce the meta model which is build by WFMC, and point out the shortage of this meta model in express ability and flexible. To solve those problems, we import the ECA rules and Activity division rules into modeling.Use ECA Rules to describe the execution logic of four kind of modeling base structure, and use some graph to show all of those base structureImport the ECA rules and Activity division rules into modeling. Put forward one kind of modeling way which is based on ECA rules and Activity division, ECA rules is used to describe the execution logic of the flow, and Activity division create some container to constraint the logic that is expressed by the ECA rules, and organize the flow as a activity tree.Designing and realized the flexible workflow engine, ECA rule resolve module,visual workflow designer, Based on this we designing and realized the Approval System.
