Study Of Inter-Enterprise Workflow Modeling Based On Object-Oriented Petri Net

Workflow management is a technology which used widely and developing rapidly, it is the core technology which can be used for enterprise business process modeling, simulation analysis and management optimization. The workflow technology can separate logic relationship of business process from the application system to the purpose of modeling, restructuring and reusing the business's process, and work flow modeling is the basis of workflow technology. The focus of workflow modeling research is on internal business process modeling now and the research about inter-enterprise workflow modeling is less. Through inter-enterprise workflow research can use the resources of different enterprises effectively and improve productivity, so it has been used more and more widely. In this paper, the method of inter-enterprise workflow modeling and analysis is studied on the basis of the Petri net theory.The contributions of this paper are as follows:1. In order to describe the relationship between object abstractly and simply, we integrated the object-oriented technology with Petri net, provided the expansion definition of object-oriented Petri nest which based on the analysis and comparison of the different existing definitions.2. We used the definition of object-oriented Petri net proposed previously to analyze and model the business process of a common system in economic operations which including the consumer, marketing companies, production enterprises and enterprises of the production supply of raw materials, got the object-oriented Petri net model of single system object and the whole system.3. According to the object-oriented Petri net model of single system object and the whole system built before, we analyzed the systematic nature about the model, including the structural liveness and the structural boundedness. The method of object-oriented Petri net model structural liveness analysis is similar to the general Petri net model, in order to analyze the structural liveness of the whole system, document [88] use the object communication network for analysis. This pear analyzed the insufficient of the object communication network and proposed the method of merging the information place with the specific transition which is responsible for communication between objects. Then we used the incidence matric and the S-invariant to analyze the structural liveness of each object so as to analyze the structural liveness of the whole system. Finally, verified the structural liveness and the structural boundedness of two objects in the actual system.4. The competition for resources is the major concern of workflow modeling, and the main task of the workflow engine is to allocate the resources, but the resources allocated by the workflow engine are computers, personnel and other resources within the enterprise. In this paper, we proposed that there are not only the resources competition inside the enterprises, but also market resources competition among enterprises, and so proposed the factors that affect the customer purchasing decision and the calculation method of decision coefficient aiming at the competition for client resources.
