A Study On Workflow Condensed Modeling For Enterprise Application

The workflow technology shows strong function and broad application prospect in the field of realizing the business process reengineering and process orientation application. At present, there is still no systematic theoretical system in the aspect of the modeling measure in existence and the research on the workflow modeling theory is backward compared with achieving technology and developing speed of the workflow product. Meanwhile a lot of modeling measure is still in the process of the experiment and the merchandised workflow product only provides limited modeling support, which results in an urgent need of a set of suitable workflow modeling and analysis measure, because the enterprise users, as the real end operators of the workflow management system, are not fully equipped with the special modeling skills. Aiming at this current research situation of the workflow technology together with the requirement of the enterprise users, this paper tries to establish a set of theoretical system including workflow meta model, the graphic workflow process modeling language, the formalization method of workflow model analysis, organizational model, the assignment of the activity participants and so on to instruct the workflow modeling.Aiming at the lack of the workflow model formalization definition and analysis measure, this paper puts forward a workflow meta model core group and the corresponding model transfer measure which has a good expansibility to solve the problem of the share of the workflow model and the interoperation among different workflow management systems. Next, the paper also brings forward a set of method to workflow modeling and the model qualitative analysis, which includes the graphic modeling measure that has user-friendly interaction, the mapping arithmetic from the graphic model to formalization model, model modularization measure, and two formalization methods based on the behavioral coverability graph and the reduction to verify the soundness and prove the function of workflow process model etc. This paper also points out a simulation method of workflow model performance analysis based on the mechanism of ant colony found food to provide scientific foundation for the business process reengineering of the enterprise.Because the frequent change of the organization model will lead to the uselessness of the workflow process model, to this model integration problem, this paper puts forward an organization meta model based on the knowledge and the definition measure of the participants, and discusses the matching policy of the participants based on knowledge and the entities relationships description in organization model based on regular expression to ensure the process model need no or little modification when the enterprise organization of different levels changes. This paper also presents the XML schema of resources requirement definition, and provides the full-length support to the complicated resource requirement in the workflow process model.The automatic optimize assignment of user task is the key of improving the efficiency of the workflow management, and the important function of the workflow management system as well. After analyzing in detail all the influencing factors and their linguistic fuzzy of user task assignment, this paper puts forward a multilevel model of the task assignment that can be combined andthe corresponding task assignment measure.After then, the design method of the weight with self-adapt ability of the affect factors also are discussed in the paper. The comparison in the experiment proves that multilevel model has very good comprehensive performance under the circumstances of the different resources configure.It is unrealistic to achieve all the requirements because there are comparatively big differences among the requirements of the users faced by the workflow management system. On the basis of this, this paper points out the design of a distributed workflow middleware FlexFlow base on CORBA, and analyses in detail the realization of the engine scheduling mechanism based on the Petri net in the FlexFlow.
