The Cost Of Construction Enterprises To Predict The Integrated Study Of Methods And Control

Under the condition of market economy, project cost control has the consequence not only in the project management but also in the building business management. The economic benefit of building firms is accomplished usually via the economic benefit of project, and the economic benefit of project is accomplished by maximizing payoff and minimizing cost. The complexities of modern project and competitive impetuosity between building firm require building firms to renew the cost supervision logos and strengthen course integration supervision of cost control. So the building firm can possess the incincible position through that approach only. The text make the cost process control as the prior study at this background and the main job is as follow:1 .The text put forward the viewpoint that cost is a system and cost possess the vivid systematicness. Through the analyses about project cost and allsidedness and operability decomposition about the project cost from multitude angle. And then, cost management should be a system and possess the vivid systematicness too. At the same time, cost sort form should be a system at some length also and possess the favorable homography with the basic tool of cost planning —Work Breakdown Structure.2. According to the deficiency of lag of building firm's cost prediction and estimation method and the time consuming course, the text put forward the exponential smoothing cost prediction model base on fuzzy mathematics, and introduce GM(1,1) of grey theory to predict cost, and do the optimized combination about this two models at last. We can use the optimized peg model to distribute weight about the cost prediction outcome through this two method and minimize the cost prediction error.3.Throught the comprehensive discuss about project cost control and analyses about the relation of cost prediction and cost planning and cost control, the text put forward that integration management is a kind of idea and principle above all, and then integration management is practical activity with the help of the idea and principle. We claim all sidedness and entirety and procedure of cost control, and the text put forward that cost prediction and cost planning and cost control in the cost process control should take turns as well as a rolling closed loop movement.
