Modeling And Analysis Of Military Procurement System Based On Petri Nets

With the military procurement information and the development of information resources need to be addressed also will be rapid growth in military procurement process more complex, how to use computers on the procurement process for automatic and effective organization and management, become an urgent military procurement need to address the significant practical problems. Workflow technology can provide to support the business process automation, in recent years has been extensive research and development, integration has become a complex enterprise information environment, business processes to achieve the necessary tools to run automatically. Therefore, this work flow from the technical point of view to study the military procurement System, hope for the procurement of military information to provide new ideas.According to military procurement-related legal provisions of the ordinance, give out the overall military procurement WF-net business model. The model has a universal. Military procurement from region to region and different organizations have different and therefore this paper layered Petri Net technology will be the overall business processes according to levels of refinement and decomposition, the formation of bidding and purchasing system and emergency procurement system. This method can hide sub-network of internal structure and a detailed description, so that the whole model has a good level of the structure.In the nature of the analysis, using a net reduction of system rules, complex network system after the reduction of the analysis of simple methods to verify the military procurement system WF-net model is correct. In the performance analysis, the use of performance-time equivalent formulas, the emergency procurement subsystems WF-net model of time performance analysis, and to improve the existing military emergency procurement process to reduce the system's average execution time.In this paper, a unit of the military procurement system work flow for the project background, and other related work full investigation on the basis of design modeling techniques based on Petri net with the actual needs of military procurement work flow model, and the nature of verification and performance analysis, the next step of the system for business process optimization and provide a basis for project development.
