Research On The Management And Controlling Model Of The Cost In Electric Power Construction Project

In recent years, electric power industry in china is developing rapidly, as one of the most important energy, electric power is the motive force source of economic growth and social stability, so electric power industry is always the focal point of the national economic development strategy. According to the electric power industry in the12th Five Year Plan, in the next few years, power system will get rapid development, constantly optimize the power structure and increase investment of the power grid construction. As the key link of the traditional project management, cost management is also the important part of electric power construction project management. Effective management to project cost, is directly related to the project cost, project profit and the economic benefits of the electric power construction enterprise, moreover, makes indirectly impact on project quality and project duration. So that, Strengthening the cost management of construction project is an effective way to adapt to the development of the industry, meet the market demand, enhance the competitiveness of their own and improve enterprise efficiency, for the electric power construction enterprises.The constitution of the electric power construction project cost is complex and diversified, throughout the project construction process. In general, distinguished from the overall schedule of the construction project, it includes up-front cost, running cost and subsequent cost; If distinguished from the resources, it includes material cost, labor cost and equipment cost, and so on. Cost classification from various angles is different, but they crossed each other, which might get the management and control to cost into trouble.In the fierce market competition environment, construction project cost management, for the electric power construction enterprise, is related to the enterprise profit. At the same time, with the steadily rising of the labor cost and raw materials prices, the cost pressure increases gradually, so that electric power construction enterprise need to enhance the capabilities of management and control about project cost in order to enhance their market competitiveness. For one thing, we should strengthen overall control to project cost, and enhance profit space of project; for another, we also should optimize cost structure, strengthen cost control evaluation, improve cost efficiency. But due to the lack of adequate guidance and practice experience, it is difficult for electric power construction enterprise to grasp the scientific methods of project cost management, The corresponding management is also lack of systematic and comprehensive.Based on the characteristics of electric power construction project and analysis of its cost control, this paper put forward some ideas and proposals for building a systematic system of construction project management and cost control. And on this basis, this paper is devoted to theoretical research, method study and example analysis from all kinds of cost control modules. The main contents are as following:(1) Build a systematic system for cost management in electric power construction project. Which makes the cost management in construction project more systematic, This system explains the methods of cost management and cost control in construction project from following aspects:organization system, labor cost, material cost and the equipment cost and other aspects(2) Establish organizational system of project cost management. From the point of organization and post setting, introduce the organization foundation and corresponding responsibilities of project cost management; optimize process of project cost management, control cost four aspects:cost plan, cost implementation, cost accounting and cost evaluation.(3) Establish the "four demension" controlling model of labor cost in electrical power project. In this research, firstly do some research on the labor cost decision, the price of overall labor cost in project are fixed, based on the theory of equilibrium price, and get research results about labor cost plan; secondly, from multiple dimensions, analysis labor cost in project with many indicators; at last, based on above research, establish the four-dimensional control model on labor cost in construction project, control system on overall labor cost is established from four angles as following: Investment allowance, marginal benefit, flexible elasticity, process management.(4) In the research on how to control the material cost, firstly, analysis the constitution of material cost in the construction project, definite the main content of the material cost in the construction project; secondly, do some research on material cost control from three aspects:material price, material quantity, circulation of material, at last, Material cost accounting and assessment are proposed based on above research.(5) Establish the machine cost control model based on the TOPSIS method. In the research on equipment cost control, first of all, do overall analysis about equipment cost from the perspective of life cycle of equipment, and give a resolution to how to control equipment cost from the angle of equipment scheme decision; Then, establish the multi objective decision-making model, and analysis the index weight with the method based on triangular fuzzy number; at last, do some research on program decisions with TOPSIS model.(6) Finally, establish the cost controlling evaluate model based on fuzzy evaluation method. This paper assess the effects of cost control from the perspective of overall project. Firstly, Cost evaluation index system of cost evaluation is established, which is complex and comprehensive, index weight is laid down with ANP method; secondly, the comprehensive fuzzy evaluation model is established in order to evaluating project cost management.
