Study On The Process Integration And Key Questions Of Virtual Enterprise

On the basis of analysis of the research status and shortage of virtual enterprise process integration (VEPI), this dissertation discusses VEPI methodologies and enabling technologies. It puts emphasis on virtual enterprise (VE) modeling methodology, process integration methodology, and implementation methodology and information framework..Chapter 1 is introduction. It expounds the concept of VEPI, introduces the VEPI developing background and relative theory; it also summarizes the VEPI research status and shortage, and points out the meaning and the main work of the dissertation. In the end, It summarizes the content and structure of the dissertation.Chapter 2 builds the VE modeling theory and methodology. It expounds VE basic concept, analyses VE architecture and main process; it studies VE modeling architecture and integrated multiple-view model, set forth an object oriented model methodology to support VE modeling for lifetime. In the end, it gives the process model and partner-choose reference model.Chapter 3 builds VEPI theory and methodology. At first, on the view of value chain, the dissertation brings out a set of process integration methodology based on value chain combining BPR thoughts, set up the virtual enterprise value chain framework and mathematics model. Secondly, the dissertation optimizes process model and simulates the key problem based on the value analysis. In the end, the dissertation designs the software integration platform for the methodology.In chapter 4, the dissertation studies process management and correspond. The appropriate implementation methodology is the guarantee of process integration project. Aim at the character of process implementation of VE, the dissertation combines the project management with workflow management tightly. It uses the project dissolution and task programming method to plan the project implementation schedule, uses workflow management system to allocate the task and watch the schedule of process implementation, and it also executes the task by project control and workflow adjusting. In the end, it studies the project schedule optimization based on Genetic Algorithm.In chapter 5, based on the theory and methodology above, it builds up the VE information frame (VEIF). At first, it studies the application encapsulation technologies based on CORBA and Agent technologies. Then, it describes the cooperation architecture by multiply agent system (MAS) based on common intent, studies how the MAS to support process integration and the key technologies among it. In the end, it gives the main function modules. To sum up, it solves the distributed and different application integration problem and gives an instance.Chapter 6 summarizes the work of the dissertation: the shortcomings and further work are also sketched out.
