Cooperative Games and Fuzzy Cooperative Games Arising from Mathematical Programming Problems

A TRANSITION FROM TWO-PERSON ZERO-SUM GAMES TO COOPERATIVE GAMES WITH FUZZY PAYOFFS

In this paper, we deal with games with fuzzy payoffs. We proved that players who are playing a zero-sum game with fuzzy payoffs against Nature are able to increase their joint payoff, and hence their individual payoffs by cooperating. It is shown that, a cooperative game with the fuzzy characteristic function can be constructed via the optimal game values of the zero-sum games with fuzzy payoff...

Cooperative fuzzy games extended from ordinary cooperative games with restrictions on coalitions

Cooperative games are very useful in considering profit allocation among multiple decision makers who cooperate with each other. In order to deal with cooperative games in practical situations, however, we have to deal with two additional factors. One is some restrictions on coalitions and the other is partial cooperation of players. In this paper we take both of these factors into account in c...

Cooperative Benefit and Cost Games under Fairness Concerns

Solution concepts in cooperative games are based on either cost games or benefit games. Although cost games and benefit games are strategically equivalent, that is not the case in general for solution concepts. Motivated by this important observation, a new property called invariance property with respect to benefit/cost allocation is introduced in this paper. Since such a property can be regar...

Cooperative Games

A coalitional (or cooperative) game is a model of interacting decision-makers that focuses on the behavior of groups of players. N denotes the set of players. A coalition is a group of players S ⊂ N . We refer to N as the grand coalition. Every coalition S has a set of available actions AS. An outcome consists of a partition of N (coalition structure) and one action associated with each coaliti...
