Whole Process Cost Management Based On The Concept Of The Construction Phase Construction Dynamic Cost Control Research

With construction projects of market economy, the project cost management directly affect the success or failure of development projects in the investment returns. The project's construction project cost management is not confined to after the clearing, the progressive advancement, pay attention to the whole process of the construction project cost management.Because of this project will cost management and the status of international cost management model to a detailed comparison of their respective characteristics and construction of a market economy, on China's cost management system and the impact of industry and the impact that the current system of cost management and the problems of the characteristics of China's construction cost management to the development trend, which refers to "promote the whole process of cost management and dynamic control."The entire process cost management thinking from our cost management person, and became the core of the project cost management guiding ideology. With this in the modern scientific management and cost accounting methods to control the cost of the entire process of management theory, based on the activity or the process of the entire process cost management principles and methods. The entire process cost management thinking, mainly on the construction cost management to be involved from planning to completion of the entire process, the reasonable cost of the project to identify and effectively control two aspects.Cost management and the whole process of project concepts for cost control in the construction phase, the construction phase establish the dynamic management of the entire process cost the thinking changed after "accounts" pattern, that process control. Use of the construction phase of project cost control principle, the investment control of the project, the actual cost will be regularly value compared with the plan to identify deviations, and the analysis of the reasons for the deviations and make appropriate corrective measures.According to the analysis of the current control methods, the writer finds that the current control of cost and schedule is separate. It is necessary to apply an integral control of the cost and schedule of a project. So this paper introduces the Earned Value Concept in dynamic cost control of a project in its operating period and establishes the applying steps.This writer introduces a numeric analysis method to convert the schedule variance based on cost variance to a real time variance so that the analysis outcome becomes more directive. To make the control more dynamic, the writer establishes a costs and schedule forecast model based on the Grey Dynamic Model GM(1,1)to enhance the approach's forecasting function.
