The Study On Bidding Model And Strategy Based On Bill Of Quantity

The bidding plays an important role in the construction corporations and affects the survival and development of these corporations. The criterion of bill of quantities about construction project has been implemented in our nation on July 1, 2003, indicatinmg that the bill of quamtities has been spreaded and implemented in our country. Study on the bidding of tender companies has become a hot topic for the experts and professionals of construction based on the bill of quantities bidding. Basing upon the tender companies, the thesis studies the calculating method of bidding price and the separating method of measure cost. The bidding model based on bill of quantities, the bidding strategies and skills of tender companies.The thesis studies the calculating method of bidding price based on bill of quantities. A nonlinear separation cost model based on utilities and rationalities of the sub-items of bill of quantities is built up to the separation method of measure cost in bidding price. Then we have got the optimal solution by using the Kuhn-Tucker condition. By analysing the properties of the the optimal solution, we find that the optimal solution could be a benchmark of separation measure cost of bill of quantities and it will build strong foundation for calculating bidding price.Bidding price of tender company is more deeply studied more from non-cooperative bidding to cooperative bidding when the bidding model is built based on the bill of quantities. The non-cooperative bidding model of tender companies based on the sub-items cost distribution of bill of quantities is built up by using the first-price sealed auction of game theory in terms of the non-cooperative. So we have gained the bidding strategies of all kinds of cost tender companies by analyzing the model.The thesis analyses cooperative bidding model of tender company by using the basic principle of game theory. At first, we classify the cooperative bidding into two cases according to the costs differences among Construction Comnpanies and analyze them through both static game and dynamic game. If the construction cost of tender companies is same, author believes that the cooperative bidding model of tender companies is likely to be a prisoners'dilemma game. Although the cooperative bidding is not steady in static and finite dynamic game, it will be realized in some cases of infinite dynamic game, and the tender companies will obtain the collective rationality and reach the cap finally. The tender companies will collude and bid a high price,...
