Abstract:In this paper, we introduce some relationships between Nash equilibrium, variational inequalities, and generalized equilibrium problem. We also investigate the relations among monotonicities of their corresponding mappings and bifunctions. The results of this paper would be the theoretical basis for further studying in Nash equilibrium and generalized equilibrium problems.

Abstract:This paper uses ISODATA and GA to construct the GA-ISODATA nestingly, in order to perform the optimization algorithms of the FCM at the same time. This method can not only complete the optimal partition on the promise of giving the number with pre-classification, but also directly get the optimal number with classification in FCM without people's

Abstract:Focusing on the ignorance of the flexibility of the agent's effort in decision, this paper biulds a model of agent's flexible effort decision model and a model of principle's design of sharecropping contract in the case of complete period-0 information, manages to prove the existence of the optimal sharecropping fraction, and compares the conclusions with those derived from the classical principle-agent models. The results show that the flexibility of an agent's effort in decision raises the threshold value...

Abstract:The auction company is induced as a third side in standard auction model which considers only bidders and seller. The auction company takes some commission from the winner of the auction. The main result is that the volume of the commission rate k has both effects on the bidder's bid strategy and the expected profits of the seller: bidder's bid becomes more passive but its expected profits is not dependent on the commission rate k; the seller's expected profit has really decreased. In fact, the commission o...

Abstract:The traditional vehicle routing problem with time windows (VRPTW) is expanded to the situation, where the time window is replaced by fuzzy due time which can represent the preferences of the customers. After asimple description of the fuzzy dial-a-ride problem, a multi-objective mathematical model for the problem is built up. Then, an insertion heuristic-based hybrid genetic algorithm is proposed to this kind of problem. In this algorithm, the modified push-bump-throw procedure is employed to handle the fuz...

Abstract:To the best of authors' knowledge there is no work done on the inventory problem with seasonal demand, shortages allowed, and resource constrainted.In this study, we propose an integer programming method to solve the problem.The proposed model not only can easily be applied to real life but also allow constraints to be added by decision maker to fit for the real world situations. Finally, some examples are included for demonstrating the usefulness of the proposed model.

Abstract:CSP (constraint satisfactory problem) has the advantage of solving complicated constraints to obtain satisfying solutions, but does not guarantee the quality of the solution. In contrast, OR (operation research) has the advantage of obtaining optimization solution or near optimization solution. But it is very difficult to solve the optimization problems with complicated constraints. CPT (constraint propagation technique) is the main search approach of CSP. BAB (branch_and_bound) is one of the optimization a...

Abstract:The paper used the Eclectic paradigm to analyze the competitiveness of MNCs. From the aspects of ownership advantages, locational factors and internalization advantages, the paper studied on factors which determined favored competitive status of Japanese MNCs in China. Based on the 230 responses of questionnaire investigation to 702 Japanese parent corporations, the authors concluded some findings. The competitive advantages of Japanese MNCs in China come from the ownership advantages and locational factors...

Abstract:The traditional evaluation methods usually depend on the market effectiveness, but it is not easy to achieve in bond market. This paper investigates the relationship between Data Envelopment Analysis (DEA) and Nash-equilibrium Theory in Game-Theory and builds game-DEA models from a Game-Theory perspective. The evaluation of investment funds via game-DEA models does not need to select market combinations, so it makes the results of evaluation more reliable.

Abstract:Based on the analysis of the characteristics of dealing between the firm and consumers as well as consumers' behaviors, a dynamic consumer choice model has been presented. Through the comparing of two methods determining discount factor in the models which take it as a constant or a parameter methods, the method of taking the discount factor as the function of consumers' heterogeneity is also presented. Results show that the functional method is better than the other two methods in applicability about the m...

Abstract:If cybermediaries support, manage and execute exchanges, transaction risk will be reduced efficiently in electronic commerce. Based on the relation among objective risk, expected risk, risk preference and risk control being discussed, the paper designs controlling mechanism of transaction risk, develops a control model for cybermediary, and proves the existence of the optimal solution. Finally, the paper analyzes the optimal controlling strategies for cybermediary under certain and variable mean risk prefer...

Abstract:The paper tries to put exchange rate pricing into the framework of whole macro economy and conducts general equilibrium research. The paper puts forward and constructs the General Equilibrium Sticky Exchange Rate Pricing Model(ESEPM) by using Keynes' classic theory as the macroeconomic framework, profit maximization of manufacturers as microeconomic foundation, strict mathematical deduction as logic link, Dornbusch's sticky price as ideological guideline, differential impact form of Purchasing Power Parity ...
