The Research On Cost Allocation And Partial Of Cooperation Method In N-Person Game Theory

With the economic globalization deepening and extend of network economic, more and more enterprises realizes that it is very difficult to adapt to complex competitive environment. The enterprises need to cooperate with each other to fit in rapid change of science and technology and run environment. Only that can the enterprises have a space in the keen competition. The thesis introduces the era background of cooperation, and gives the thesis's point of departure and meaning. Cooperation is the theme of the thesis.The article consists of two aspects content:One is the issue of cost allocation. First, the thesis gives the cost allocation model of cooperative game, and introduces some ways to solve the problem of cost allocation at present. Second, it illustrates that a method's proved exists the matter. Then, it advances a new method of solving the problem of cost allocation, and proves it. Third, it gives an example for comparative analysis, brings out its feasibility, rationality, fairness to the best advantage. Last, it discusses the solution of the problem of cost allocation in cooperative game, which exist necessary requirement.Another is partial of cooperation in n -person game theory. This article is based on the game theory of basic knowledge, dominant strategy and iterated elimination of dominant strategy definition and application of partial cooperation background, in theory examines the issues what in many players game theory, some of them formed a strategic alliance Whether or not have the strategic choices and equilibrium manner results to influence for players. Through discussion the following conclusions can be drawn: If partial cooperation former strategic approach to dominant strategy selection, after cooperation, dominant strategy changed into iterated elimination of dominant strategy, dominant-strategy equilibrium is also changed into iterated dominance equilibrium; If the players choose strategies in the former partial cooperation is the way to iterated elimination of dominant strategy, But Only in certain Union, after the players in cooperation, iterated elimination of dominant strategy is not changed, iterated dominance equilibrium is maintained; However, there are also some strategic alliances in ways that do not have any choice of law, correspondingly equilibrium is unpredictable. Last it talks over a problem that in the many players game theory, if two players make up an alliance, refer to cooperation engendered payoffs, they are how to distribute it fair and reasonable among two players.
