Design Of Distributed Intellectual Bidding System In Internet Based On Game Theory

The history of tender and auction is glorious. Far from the time of ancient Babylon, people had used the way of auction to sell their wives. In nearly 2000 years of development , the people have made the massive discussions to the auction theory and technology, specially with the rising of IT, causing the transition from the traditional auction tender to tender in Internet. This thesis make the correlation research on how to establish the system of bidding in Internet , building the intellectual system of bidding in Internet based on Agent;giving the Agent's strategy of bid and tender mechanism based on game theory , designing the corresponding distributed algorithm in view of the tender mechanism and bidding strategy;finally , giving the protocol of security transaction in Internet after having completed bids .First, in the system design, this thesis is to construct the frame of bidding in Internet based on Agent, elaborate each Agent's function and the overall system commercial flow in detail, designed the basic structure of Agents in bidding system on the foundation of discussing the theory of Agent and the method of cooperates and communication between Agents, discuss the method of cooperation between Agents , give the communication frame between Agents based on XML, KQML and the ORB;Second , the thesis also applies the basic principle of game theory to discuss the Agent's strategy of bid under the situation of convention and plot bids, corresponding to the strategy the bidding Agent may take , design the tender Agent's conventional mechanism and the counter- plot mechanism having retentional price, and carried on the analysis to correlated supposition in the game theory;Third, the thesis designs the distributed algorithm bidding in Internet corresponding to the frame of system and strategies Agents take . In this algorithm, using examined mechanism to solve the question of the data transmission mistake and data conflict, using secure mult-party computation to solve the problem of making decision of bids in secret, and using bit commitment to guarantee thegood faith of bidding Agent, guarantees the algorithm's reliability, secrecy and cheat against to the greatest degree;Finally, in the foundation of DAS S protocol, it designs the protocol of Agents' status recognition , the key exchange and how to use the key to carry on the consultation of the electronic contract , signature, bank account transfer and so on.This thesis conducts the systematic research to the model of the intellectual bidding system in Internet , based on mechanism of Agents and related algorithm of model, gives a good solution to the technique problems which the bidding in Internet is facing , and provides a kind of good solution to establish intellectual bidding platform in Internet...
