The Research On The Cost's Dynamic Control Of Engineering Project's Operation System

The engineering project has the single unit, the disposable characteristic. The engineering project work is based on the scene of produces. The scene of produces is referred to the place where products are produced , it is the foundation spot which the intensive production and the transform of the growth way are based on, namely where the worker utilizes the means of labor, affects to the object of labor, completes the certain production work task . However, the scene of produces cost is the divert value of materialized labor which is consumed in the production process and the currency performance which is equal to wages that part of human labor creates the value. The enterprise scene materialized labor and the human labor consume the production cost which forms the enterprise most foundation level cost. This article embarks from science development view, utilizes the best production method analyzing characteristic of the cost management. Therefore according to the eleventh five-year plan about the transforming of economical growth way. It has the vital significance to the enterprise, including controlling the cost forming process of the product and the service, the improvement of the movement mechanism of the scene of produces, the excavating the potential of enterprise's scene of produces, constructing the harmonious enterprise . Therefore, it is necessary to conduct the research to the controlling of the cost of project scene.Langfang prevention engineering firm which was just founded in recent years was leaded by China petroleum. It is engaged in the construction of fire project. The set of cost controls method which carried out now already slowly demonstration its malpractice, and it was seriously affecting the company's profit volume, some problems which was in its job location cost control has affected its development.This article first obtains from the engineering project scene management and the cost control concept, has carried on the description to the job location cost control situation, conducted the investigation and studied the Langfang prevention engineering firm scene cost control present situation, according to the company cost management at present, applying the cost of operation ,the target cost management pattern as well as several steps which has carried on the multianalysis to the fire company's scene cost. In addition, has summarized the firm's some engineering projects cost situations, improve prevention engineering firm experiences to theory level. Then, has studied the questions which was existenced in the prevention engineering firm scene cost management , has established the job location cost control model,has proposed the consummation and deepened the prevention engineering firm scene cost control pattern conception, provides the model and the reference take to other construction enterprises' cost controls, and makes the further research forecast.This article has the innovation on these two part, embarks from the engineering construction project foundation level (namely the scene of produces),conducts the research to the cost control; conducts the entire journey dynamic control research to the project work cycle from setting up the item to arriving objection.
