Research And Implementation Of Modelingand Simulation Technology For Cross-organizational Workflow

In the era of economic globalization and information technology, with the rapid development of the extended enterprise business, and computer network technology, business processes involving multiple organizations, collaboration between enterprises are greatly increased. Workflow is the core technology of modern enterprise business process automation. Thus cross-organizational workflow technology is widely applied to the adjustment of enterprise business process, optimizing and reengineering. The purpose of this study is to analyze how cross-organizational workflow is used to participate in collaborative business process better.First of all, this thesis introduced the domestic and foreign research status of workflow technology. The existing problems of cross-organizational workflow are summarized in it. Furthermore, computer supported cooperative work technology, the concept of Cross-organizational workflow, workflow management system architecture and related key technologies are introduced.Secondly, with reference to the workflow reference model, combining with the industry on enterprise process modeling technology, an architecture of cross-organizational workflow model is constructed, which is composed of process model, organization model, resource model, behavior model and collaborative model and data model. Center with the process model and collaborative model we can realize synergy of cross-organizational workflow. A cross-organizational workflow visual modeling language COVPML is designed based on the visual process modeling language VPML, and the expression of language form and object primitives are also presented. To research cross-organizational workflow modeling method can help in using the enterprise process modeling system EPMS for business process modeling.The feasibility and effectiveness are validated through a case of study within cross-organizational workflow modeling.Finally, the simulation technology of the cross-organizational workflow is studied and implemented by using the cooperative rules and scheduling strategies to achieve the coordination across-organizational business process. In this way we can use it control the execution order of each business activity in cross-orgnizitional workflow.
