The Study On The Modes Of Project Cost Controlling

The project cost controlling is one of the cores of modern project management. The one-off and limited resources of project determine the difference of the modes between project cost controlling and product cost controlling. The first, quality, progress and cost make up of the basic elements of project, and the balance-off of cost and progress is the key points of cost controlling with unchanged quality. Cost will change if duration is guaranteed because of the specific duration. Duration cost is not paid enough attention .The second, project is surrounded by a complexity. The change of surroundings will bring about the change of project cost. The project cost controlling is based on the risk that makes the cost changed. Without effected measures of analyzing, weighing and monitoring the goal cost is also not achieved.To resolve the above-mentioned problems, the balance-off of progress and cost is put forward at the first. Work breakdown structure is the basis of project controlling and the model of duration-cost is put forward with the analysis of time and cost. AHP and FCE is used to weigh the risk of project cost, which is the basis of risk controlling. The second, in theory preceding controlling is brought forward and meanwhile the values for work performed and budgeted cost for work performed are used to control the project cost in practice. At the last, the model of performance evaluation based on cost, progress,quality and safe is brought and the standard of project success is discussed too, and the case of Liaoning power plant is applied.
