Project Cost Based On The Ahp Analytic Hierarchy Process "super" Risk Control Study

China's annual investment in the construction industry is increasing funding, the project has also kept the total amount of the increase in cost in recent years appeared more than 100 billion Yuan in the project, such as Beijing-Shanghai high speed railway, Shijiazhuang to Guangzhou Railway.The current of China's construction cost over remained relatively serious risk of project cost is relatively late start, and the lack of specific and practical, mostly to stay in the empirical analysis and qualitative analysis, did not form a well-established.The project cost risk management system.View of this, specifically construction cost premium for the study, explained the whole process of project cost management, and construction cost of the components are also introduced, but also introduces the risk identification, analysis, evaluation, estimated the risk of dealing with this 5the concept of the process and methods in.And the whole process for the project cost control project cost may occur in the risk premium on a detailed analysis.AHP subsequently introduced into the risk assessment process, to improve the accuracy of risk assessment model, will rate it with expert, which combined expert scoring method based on qualitative and quantitative model structure; seek to establish a with the whole process of project construction cost risk premium model, so that construction cost premium in the early stages of the project can be controlled.In addition, based cases, a detailed description of the model into use.This paper will focus on understanding the whole process of the project, based on analysis of project cost premium in the whole process possible risk factors.Then based on a hierarchical analysis of project cost premium to quantify the risk factors, the process we have introduced expert scoring method to improve the accuracy of our model, the final level of analysis to establish a project cost premium model.This method can overcome the past alone for a premium experience to the shortcomings of risk control, good maneuverability, let us know in advance the risk of project cost and risk premium level, and can take countermeasures in advance to minimize the cost premium place.
