Research On The Whole Process Cost Management System Of Grid Project

Power grid project has a wide range of regional, design conditions, large differences in uncertainty and many other features, which has brought a high degree of difficulty for reasonable cost of the grid project. At the same time, the grid project in the design, bidding, implementation, completion and other aspects of the relatively independent.Using the existing theoretical results, have got a comprehensive analysis of the grid project, summed up the power grid project cost management status, to carry out the follow-up application practice laid the theoretical basis; at the same time, the characteristics of power grid project management, power grid project management Characteristics, to explore the targeted, strong operation of the power grid project cost management control methods, and ultirmately achieve the purpose of improving the project cost. Foreign power grid project for the cost of management have established a special management system. From the development of project cost,most of the developed countries based on the construction of the economy,management, technology integration, the project pricing and control fully integrated with the management of science, the establishment of a series of project cost control theory. Most domestic scholars in the project cost management research is based on some foreign research theory. In the course of the study, it is found that there are many problems such as imperfect law, imperfect system, and incomplete scope and so on. On the whole, the domestic scholars for the study of the project cost not only contains the problem of mining, but also includes the proposed countermeasures.According to the progress of power grid project in the implementation of the progress and management of the different focus, the project stage is divided into investment,the objectives of the various stages were set. Analyzing the important factors that affect the project cost, and picking out the key factors of controllability, and constructs the control index system. The overall goal and sub - goal of grid engineering cost are analyzed, and the basic level of control model is constructed with control stage and control index. Through achieve the overall goal, as well as for the overall goal and the realization of each sub-target, the importance of control indicators sort. With the aid of the weight of the AHP control model, the comprehensive score of the control efficiency is solved, and the validity of the cost control and the overall validity of the whole process cost control are evaluated.Through the empirical analysis, the efficiency control score of the control model is used to evaluate the cost control and management efficiency of the empirical project,and the key control index of the control failure is analyzed by means of reverse analysis to find out the important reasons leading to poor control efficiency.Through the analysis of theory and case, the paper discusses the applicability and concrete process of the whole process cost management in the cost management and the construction and application of the cost management system based on the whole process cost management, which provides the whole process cost for the power grid engineering. New research perspectives and methods, the research results will help to improve the level of power engineering cost management, reduce the possibility of the occurrence of the accident, and can provide reference for project management, safety management and maintenance management.
