Research On Multi-item Double Auction Mechanism Design And Fuzzy Game Theory

It is obvious to all that the Web and E-commerce developed rapidly. Many of the key part of business transactions, such as search capabilities, security, authentication, and payment processes, have been supported. However, the negotiation reached a contract agreement is still an expensive process, requiring manual process. It is difficult with the network and e-commerce support. As an effective resource allocation and pricing mechanism, auction shows a fair, just and open principle. It achieves a rational and effective allocation of resources, and achieves the efficient operation of e-negotiation phase, just to make up for lack of other forms of e-commerce pricing part. Therefore, online auction in theory and practice have arosen widely attention of scholars. However, due to its rapid changes and the complexity and diversity of its mechanism, the research and application of auction mechanism is faced with higher and higher challenges. Also, because the auction is asymmetric multi-stage game in uncertain environment, auction theory research bristles with difficulties, and theory application has a bumpy ride. Most of researches current are based on some assumptions and constraints strict and far from practical use. Compared to the rapid development of online auctions, auction theory, evidence and application are relatively backward, urgent needing extensive deep researches. The major work of this paper mainly includes:1、After reviewing a large number of domestic and international journals, books, conference papers, research reports and other relevant literature, theory researches, experimental studies, practical applications of auction are reviewed. Analyze in a networked environment, the developments and expansions of auction application, and the new features appearing. Analyze of online auctions and e-commerce and development process of promoting each other’s.2、Design the mechanism of multi-item double auction. The mechanism can determine the clearing price and match between multiple sellers and multiple buyers involving multi-item. It’s proved that the clearing price reflects the true relationship of demand and supply, and the mechanism follows the principle of incentive compatibility. So, the mechanism is the price discovery mechanism realized fair, just, and public. There are four principles in matching:pro rata average principle, first bid first win principle, amount priority principle, and user grade priority principle. If extended, it is also fit for the classic auctions, which proves the validity and broad applicability of the mechanism.3、Analyse and design the mechanism of B2T(Business to Team). Analyse the formation and character of B2T. Based on B2T, research the sellers’ strategy, and determine the optimal discount strategy based on analyzing the buyers’ types and their distribution combined with market informations.4、Propose English auction model based on fuzzy game, and analyse the mechanism of online English auction. Define fuzzy sets to represent the auction participants’ bid wills and win possibilities. Study auction participants’ actions and decisions using Bellman and Zadeh’s concept of confluence of fuzzy decisions instead of the game theoretic Nash equilibrium. Propose static equilibrium and dynamic model for English auction based on fuzzy game theory. The simulation-based Particle Swarm Optimization (PSO) approach is applied to solve the problem, which proves the validity and efficient of the model. The dynamic model simulates the human behaviors and decisions with the network environment full of information, which should be used as theoretical basis of high intelligent auction agent. Analysis and design the mechanism of online English dynamic auction based on theoretical model.5、Propose double auction model based on fuzzy game. It’s very difficulty in modeling and anylyzing for auction, because auction is dynamic game with multi-person multi-phases and information asymmetry. Multi-item double auction is one of the most complicated mechanisms of acution theory. The double auction model combines double auction mechanism and fuzzy bidding equilibria models.6、Analyse online auction business process management based on process algebra. Networking demands auction business process to be more flexible to adapt to the changing envieonment. Implement quantitive analyse and management for business process based on process algebra, and flexible business process management for online auction with high adaptability.
