Virtual enterprise has been considered as one of the most promising business strategies in the 21 Century owing to its capability to integrate resources from various enterprises to meet the rapid market changes. The implementation of virtual enterprise highly depends on the nature of business processes and involves technologies of management, reengineering and information. Due to the complexity, there is no commonly acceptable methodology for implementing virtual enterprise. Therefore, the goal of virtual enterprise is still far from reached. The objective of this research is to develop a methodology for business process virtualization to facilitate the implementation of virtual enterprise and thus help achieve the goal of virtual enterprise. To obtain the research goal, tasks conducted in this research include business process modeling, virtual enterprise analysis, process virtualization methodology development, system integration planning, and methodology verification. Since the key idea of virtual enterprise is enterprise integration, the proposed methodology includes the phases of process integration and system integration. In the phase of process integration, a process is first configured based on the characteristics of product to develop or to manufacture. The methods of dimensional analysis, matrix analysis and dynamic programming are then used to determine capable partners and build an initial “virtual process”. The initial virtual process is evaluated using PERT method based on the time. In the phase of system integration, a material flow model, a process control configuration, a system configuration, an information flow model, and a relational data model are created for system implementation according to the virtual process model.
