【正文】 roject cost of the basic concept, of the engineering bill pricing model under the cost structure, to accurately predict costs of the project provided the basis, considering the average cost of the social cost to individual enterprises and the tender stage of the cost estimates. Followed through on fuzzy math and technology for smooth indepth analysis, through closedegree, the concept of reasonable fuzzy math and exponential smoothing technologies, construction of the project cost vague prediction model, and in accordance with the relevant information and statistics Information and experience to establish a framework structure, the parison works Construction Cost Management from the quantityone price plan model to price of separation volume model of the market, and gradually establish a market pricebased price formation mechanism, the price of the decision in the hands of the parties involved in the market, and ultimately the allocation of resources through the market in order to realize through the market mechanism to decide on project cost. This will standardize the construction marketpetitive behavior and the promotion of project bidding mechanisms play an important role in innovation. It can be said that the implementation of the project bill of quantities is a project cost management system in our country a big step forward, but also in China39。s accession to the WTO, the global construction industry a powerful tool for peer petition. A healthy bidding system should be in accordance with the open, fair and justice and the principle of good faith, and establish a unified, open, petitive and orderly construction market. In view of the current problems existing in the bidding process, adopt regulations, and formulate and perfect the institution, strengthening process supervision measures, they can better regulate construction market order, prevent corruption from its source, purify construction market, promote the construction market order progressively toward standardization, institutionalized, and constantly improve the quality and level of the bidding work.
