Flexible Workflow Modeling, And Dynamic Modification Of The Simulation Study

Workflow is a key technology in process integration of modernenterprises, it can make the process automatized. Because of diversifiedfactor, enterprise's process need to make some dynamic modifications toreact all kinds of requirements,but workflow productions in nowadays arenot allowed to change in run time. Therefore, the flexible workflow is oneof the most important technology that we need in order to improve theflexibility of WFMS.This paper does a elementary study of flexible workflowmanagement. After analyzing the business process of enterprise,we builda workflow model which desicrible from enterpriseprocess,organizing,role and aim-controlling.Process-modelling is thekernel of the whole model.It adopts the From-top-to-down modelingidea,denotes the business process based on tree-decomposed method byPetri-nets form.This hiberarchical decompose method is not onlypropitious to distinguish process ,sub-process and activity, but also help tocarry through dynamic modification.Based on the established workflow model, we analyze themanipulation of dynamic modification and some structure conflict whichmay be exist workflow-nets,and then discuss dynamic appending anddeleting activities, enumerate some feasible operation.After finishing dynamic modification,the workflow model have been changed.Forvalidating the changed model,we propose a arithmetic which can achievethe target.It affirms there is no structure confict mistake in the model.In the end we do a program to emulating the flexible workflow,confirming the correctness of flexible modification.
