On the base of the nature of Shapely Value, the construction of Shapely Value in cooperative game is analyzed in this paper, and it is concluded that Shapely Value is made up of two parts, one part depends on individual itself, and the other part depends on the state of individual in alliance. Then the construction of Shapely Value is used to discuss the enterprise alliance and the rent of enterprise...
In real life, because of the limited rationality and lack of information, it is difficult for experts to give accurate judgments. A grey number is such a number whose exactly value is unknown but a range within which the value lies is known. Therefore grey number from grey system theory provides an important and useful tool to help describe the judgments of experts. The typical grey numbers include...
The core of establishment of enterprise alliance is the profit allocation of the member, and enterprise alliance is the result of group decision-making of all members. The paper advances a method combined with Shapley value and group decision-making model to solute the problem that how to get the function of enterprise alliance in Shapley value model. On the basis of these, the solution of model is...
A gray input-output model based on the standard interval grey number, the condition of convergence of M steps grey matrix and the solution method were given, then produced the corresponding mathematics proof in this paper. The model and solution method obtained a good result in the solution process of the gray input-output model. Finally, the validity and feasibility of this model was confirmed when...
In this paper Grey Graphical Evaluation Review Technique (GERT in brief) Network is put forward and its model is built up, for the method of GERT Network requires accurate parameters of action, and however, people usually cannot find out exact value of parameters because of limited information of real life. By Grey GERT Network, many actions are easier to be described and discussed. This paper defines...
One category chain model of evolutionary game is proposed to study the process of some economic conditions. It could be used to describe some real life conditions that the income of some one is in strong correlation with the stage at that time he makes decision, and also condition that decision maker is with bounded rationality and limited knowledge. This paper discusses its evolutionary stable strategy...
The most fatal flaw of the classical Cournot oligopoly model as well as the related oligopoly output-making competition model is the supposition on the purpose of game players. It thinks that the only game goal is to make the present profit maximum. Based on this supposition, most game model structures are optimal structures. In this article, some new suppositions of duopoly game are established,...
