Study On Decision-making Of Management Based On Game Theory And Rough Set Theory

Game Theory pays more attention to study the best choice on the condition of mutual action, and the best choice is influenced by other choices. Its conclusion fits for reality and is practical. It can discover many origins and rules of economy and help people to analyze the relationship of economy, recognize the phenomena, and instruct people to make scientific strategies. Game Theory is significant to the strategies of management. Rough Set Theory is a tool of Data Mining to solve obscure and non-accurate classification problems. It can refine attribute properties and find the results and rules by analyzing large numbers of data So it can help to discover asymmetric information of the games on a certain extent.The paper analyzes mostly the strategies of management based on Game Theory and Rough Set Theory, studies decision-making and equilibrium results by building games' models on the condition of decision-makers'mutual action. The content of the paper includes: firstly, the games of the manager and the owner, because the manager is apt to choose the departure action of the owner's will. The owner should inspirit and supervise the manager in order to gain more benefits. But the supervising cost is very large, so the owner gives more inspiration by maximizing the manager's benefits. It makes the games achieve two maximum benefits. Especially in the games of asymmetric information, the paper builds different reward contracts to reduce the extent of asymmetric information. Secondly, the games of the manager and the employee, because of the conversal choice and moral venture of the employee during applying for a job and working. The paper builds a signal game and repeated game models to avoid the employee's cheat and laze. Thirdly, the games of the manager's investment, the paper analyzes the conversal choice during selecting the investment items and several managers' strategies on drawing the output, the paper builds the game of manufacturers' noncooperation, the game of manufacturers' cooperation, the game of manufacturers' fake cooperation, the dynamic game of anticipative predominance and the game of repeated to analyze the investment strategies. Fourflily, the games ofmanager's sale, the paper builds a game model to analyze the harm of price war, which is a universal way that the manager adopts and gives the proposals of getting rid of the prisoners'dilemma.In addition, because the manager and the employee have asymmetric information, the paper builds Rough Set model to find the rules of the employee's real information, which helps the manager to select and evaluate the employee. In the strategies of investment and sale, the paper builds the Rough Set models to find the investment and the sale's rules, from the different point of view to analyze the strategies of investment and sale.
