Research On The Project Integrated Management Mechanism

Implementation of the Project Integrated Management Mode can improve the construction project performance significantly, and be considered as one of useful influencing factors to promote the project management level and to enhance the core competence of the A\E\C industry in China. Successful implementation of the project integrated management mode is resulted from both integrated management technologies and integrated management mechanism. Hence, it is important for us to research and design the project integrated management mechanism which is considered as key factors to increase the success rate of the project integrated management mode implementation. Similarities and differences between economic system and the project integrated management system are analyzed. Results show that there are 3 main different aspects, including information cost, process controlling and environment-dependence. Thus, main contents of the project integrated management mechanism design can be divided into 3 categories: 1) Incentive compatibility constraint; 2) process controlling mechanism design and 3) environmental adaptability design. Furthermore, elements, principles and framework of the project integrated management mechanism design theory are concluded and constructed.Characteristics and dynamic mechanism of the project integrated management are analyzed, and the project integrated management mechanism system is designed by the project integrated management mechanism design theory. Results show that the project integrated management mechanism system can be divided into the following: the incentive mechanism, the restriction mechanism, the process performance regulation mechanism, the coordination mechanism, the decision-making mechanism and the adaptation and evolutionary mechanism.Based on the principal-agent theory and game theory, the incentive mechanism of the project integrated management is designed, results show that profit allocation and agent selection are two core problems in fitting the incentive compatibility constraint of the agent. Then, profits of the project integrated management which can be categorized into direct economic profits and intangible profits are identified, and a two stage model for the project integrated management profit allocation is established.The internal restriction mechanism of the project integrated management which is separated into the credit punishment mechanism, the guarantee mechanism and the reputation mechanism, as well as the external restriction mechanism of the project integrated management which is constructed by the market competition mechanism, the legal restriction mechanism and the social restriction mechanism, are designed and presented.The coordination mechanism and decision-making mechanism between participators of the project integrated management are designed, and the process performance regulation mechanism of the project integrated management is presented. Furthermore, a process performance evaluation index system of the project integrated management is established, and an evaluation method is constructed by using the modified analytic hierarchy process (AHP) method and the fuzzy comprehensive evaluation method.Based the self-organization theory, it is considered that the project integrated management system can be seen as a complex self-organization system, and there are 3 order parameters which are integrated objectives, information sharing and cooperative project culture. The adaptation and evolutionary of the project integrated management system in which catastrophe phenomenon may be emerging relies on the establishment of the dissipative structure. The catastrophe model and the dissipative structure model are constructed to simulate the adaptation and evolutionary path of the project integrated management system, and conditions which the dissipative structure could be constructed in are analyzed and presented.Achievements of the paper are tested by analyzing and researching the project integrated management mechanism of the Extension Project of Shanghai-Nanjing Expressway, which normally is seen as a successful implementation of the project integrated management technologies. Results show that: settings of the project integrated management mechanism of the Extension Project of Shanghai-Nanjing Expressway are basically correspond achievements of the paper, which means that achievements of the paper are supported by results of the case study preferably.There are 54 figures, 13 tables and 254 references in the paper.
