Study On The Construction-agent System In Railway Construction Project

Railway is an important part of comprehensive transportation system in China. In recent years, China is carrying out large-scale railway construction. To improve the management level of railway construction, strengthen the construction management of the railway construction project, the search for the appropriate management model of railway construction project is of great significance. In view of the disadvantages of traditional management model, the State Council put forward the construction-agent system for non-operating government investment project in 2004. This dissertation discusses on the theory and application of the implementation of construction-agent system in Chinese railway construction project in order to guide the practice of railway construction better.The management model of the domestic and foreign government investment project is summarized, and the traditional management model and its characteristics for Chinese railway construction are analyzed especially. The concept, theoretical basis, origin and development of the construction-agent system are introduced. The necessity and feasibility of the implementation of construction-agent system in Chinese railway construction project is demonstrated. Based on the practical experience and theoretical analysis, the operation mechanism of the construction-agent system in railway construction project is established. That is, socialized project management enterprise qualifies as agent by competition, and takes the responsibility of whole procedure management of the construction project. The agent and the supervisor all conclude a contract with principal directly.The implementation of construction-agent system in railway construction project is an institutional transition. This needs the relevant supplementary measures to give full play. The theories and the methods of the construction-agent system in Chinese railway construction project are systematically investigated. The relevant supplementary measures such as the methods for selecting agent, the risk aversion measures and performance evaluation system are comprehensively analyzed according to the project construction procedure.The appropriate method of bid evaluation in construction-agent system is the key step towards success. The pattern of selection for agent is analyzed. The conclusion is that agent selection should adopt competitive bidding. The index system of bid evaluation is presented. The evaluation method which based on DEA is put forward.As a new management model, construction-agent system should not bring new risks for railway construction project. The risk in construction-agent system is analyzed by establishing mathematical model. Several measures to avoid those risks have been derived from the analysis.As one of the measures to avoid risks, the performance evaluation system is established. The index system of performance evaluation is obtained. The mathematical model of performance evaluation is proposed based on extenics. The measures which the agent may take to supervise other relative construction companies, especially for the performance of construction company are studied. The fuzzy comprehensive evaluation model for green construction is constructed.Finally, the research work and research results of the full text are summarized. The paper's innovation and the inadequacies are pointed out. The further work for further study is expected.
