Bid Quote Price Game Model

Actting as an important method of construction projiec, bid problem gives rise to attration. People gradually reconginze this researhch' value.Since the bid method is so important that the theory about it is being developed quickly. Combines the thought of game-theory and the cognition of bidder's quoted price, the first-price sealed game-theory based ,this paper investigates the cognition game model of bidder's quoted price .The key problems as follows: First of all, while in the progress of the bidding making, its not reasonable to consider that the bidder's quoted price would be one forever. The classed models analyzed the game phenomenon under the hypothesis that bidder's quoted price should do so. Obviously ,this hypothesis is too far away form the reality. In order to conquer this weakness, we took on the research of the cognition of bidder's quoted price while he in competitive environment. Second, considering the un-cognition between the bidders' quoted price, we adopt the method of Luna which is using the single-lay perceptron to achieve XOR function. Just for this kind of net couldn't do that ,so Luna map this un-cognition to all un-cognition phenomenon. Based above thoughts, we build the cognition game model of the bidder's quoted price, and adopt the benchmark table of Luna to choose the ability of the bidders. By the method of geometry and logic analysis we bring out the theory under the benchmark table. On the other hand, to revise the parameters of our special double-lay perceptron, adopt the method put forward by Luna that is called gradient vector method. While we simulate this model, adopt the ERA scheme, and carry out on the Swarm software frame. In the result figure, we probe the win-PROB and the proportion figure of the bidder's quoted price, and from those figures we choose the winner. Finally, illustrating the example of two bidders, and explaining the reason of hidder order's production exactly, we apply the first-price sealed game to get the same result, open out the essential characteristic of the bid game theory. This paper make great efforts form the point of cognition of bidder's quotedprice, to profoundly research the progress of the quoted price how it comes into being. On the other hand, our work has no precedent ,so the success of this model would pioneer the research of the bid problem, bring new thought and methods for the bid researchers.In one word, our work has the profound value, and the model we've build move forward the bid research.
