Research On The Total Cost Management For The Highway Based On WSR Methodology

In the last few years, invested the massive funds to carry on the highway construction in china. But, according to the statistical data analysis, the highway construction cost rises continually, restricted the investor to carry on the highway construction investment the enthusiasm. Therefore, the development highway construction cost management's research, enhances the investment and the social efficiency of highway project, completes the Eleventh Five-year Plan of highway construction development targets smoothly in china, has the very vital significance.This article analysis the highway project implements the total cost management existence in our country present situation the limitation, proposed that the total cost management materially is an advanced management system management system project. The total cost management system management system is a typical complicated system, by many essential factor constitutions, the concrete manifestation for the human, the machine, the material, the method, the environment and so on, between the essential factor has the complex misalignment relations. Because the total cost management's implementation is a complex systems engineering, must use the systems science and the systems engineering theory and the method instructs, but the Wuli - Shili - Renli (WSR) the methodology is instructs the total cost management implementation one efficacious device. This article discussed has instructed the international advanced management with East's systems engineering thought in the Chinese highway project the implementation situation.This article to implements the total cost control law"the Wuli","the Shili","the Renli"to conduct the research separately. The key point is"the Wuli"construction cost definite formula, controlling index system, information system;"the Shili"construction cost control method model and tool;"the Renli"the organization pattern and the role explanation , the cooperation promotes the person and the construction cost engineer's responsibility and the intelligence request, training and the education. Proposed that based on the WSR total cost management implementation's step, and carries on the analysis and the proof through the project example operation.The total cost control is the process which improves unceasingly, proposed that the multistage dynamic fuzzy assessment methods carry on the achievements appraisal to it, control which the implementation continues, the promotion achievements improvement. Establishes the continual appraisal quantity and the evaluating indicator system, determined that the evaluating indicator the zero dimension processing method, and obtains the fuzzy assessment method through the example in the highway project construction cost control feasibility and the serviceability.
