Study On The Theory And Method Of Integrated Control Of Construction Project Cost

Whether the control progress of the project is effective, it will decide the final benefit of society and economy on the protect. However, it's the key of the success or failure whether we could validly and accurately fix the control goal and effectively command the project according to it during the project implementation. In the light of cybernetics, a construction project is a goal system composed of many goals and inherent interaction, among which cost, progress , quality are three essential goals. During the project implementation, these objects emerged as the total control object of the whole project. Thus, research on the theory and method of project cost integrated control is essential and necessary.The dissertation will put forward the basic theory and method of project cost integrated control based on the theory of integration and management, economic and cybernetics.Fist, we analyzed the theory and method of project cost control and integrated management ,introduced it in project management and put forward the connotation and characteristic of project cost integrated control which being defined as the project cost integrated control is the entire and whole mode of project management: Its guideline is the integrated management. Its core is the system of cost, progress and quality. Its base is the theory of integration of qualitative analysis and quantitative analysis. Its characteristic is comprehensive, general and systematic. Its principle is whole, timely, dynamic and practical.Second, we introduced the conception and the principium of the earned value management, on the basis of which, the quality parameter is incorporated and project cost integrated management come into being.Third, this paper presents the cost-progress-quality integrated control mode using multi-attribute utility theory. Applying network planning techniques and improved genetic algorithm, the most satisfied result can be obtained.Last, we focused on typical case to show the effect of integrated control mode.
