In recent years, business process reengineering popular at home and abroad, it certainly has its charm. Since the advent of BPR, the U.S. and Europe, many enterprises have tried, proved through practice BPR is indeed a feasible and effective method of change, reform to enhance the competitiveness of enterprises, optimizing the enterprise’s business model, so that enterprises can complex in an invincible position of market competition to maintain their vitality for sustainable development. In China, since the introduction of business process reengineering was after, many companies realize the importance of change and began to employ the relevant experts, combined with the particular circumstances of the enterprise, attempts to apply change management theory BPR methods, in order to enhance competition force, better survival and development.However, business process reengineering theory into practice when many companies have paid a high price, but did not succeed. BPR implementation of the high cost and long process, so many companies are discouraged. Information shows that European and American companies BRP, the failures are much higher than the success of reasons: on the one hand, employees including the leadership did not abandon the old concept of a fundamental, can not fully accept the new management concept; the other hand, , BPR implementation guidance on the lack of systematic approach, not very effective tools.Therefore required to find a systematic analysis of the implementation of appropriate BPR tools are important, both to ensure the implementation of the BPR process of systematic scientific methodology as a guide, but also can reduce the risk of implementation. Through analysis and comparison, select the method of Petri net modeling for BPR as a support tool. In the enterprise business process re-thinking changes, the view of the system and process reengineering theory, Petri net based modeling method for modeling and optimization process, is particularly concerned about the relationship between business activities, activities and efficiency of their response time, and the whole process of re-integration, in addition to integrated business processes for performance evaluation. Hope the business process reengineering methodologies play a certain reference.
