Banzhaf values for cooperative games with fuzzy characteristic function
(Taylor & Francis, 2021)
The Banzhaf value, which determines the power of each agent in a cooperative game, has been used in the literature to analyze fuzzy cooperative situations. In this paper, we propose two Banzhaf values for games with ...

A Value for Graph-Restricted Games with Middlemen on Edges
(MDPI, 2022-05)
In a cooperative game with a communication structure, a graph describes the communication possibilities of the players, which are represented by the nodes. We introduce a variation of this model by assuming that each edge ...

Cooperative games under augmenting systems
(Society for Industrial and Applied Mathematics, 2003)
The goal of this paper is to develop a theoretical framework inorder to analyze cooperative games inwhic h only certaincoalition s are allowed to form. We will axiomatize the structure of such allowable coalitions using ...

A real Shapley value for cooperative games with fuzzy characteristic function
(Elsevier, 2021-04)
There are cooperative situations in which the players have only imprecise expectations about the profit that can be obtained by each coalition. In order to model these situations, several families of games have been ...

A characterization of the Shapley value for cooperative games with fuzzy characteristic function
(Elsevier, 2020-11)
The characteristic function of a cooperative game determines the payment that each coalition can obtain when the players in the coalition cooperate. But there are cooperative situations in which the players have only ...

Games with fuzzy authorization structure: a Shapley value
(Elsevier, 2015-08)
A cooperative game consists of a set of players and a characteristic function which determines the maximal gain or minimal cost that every subset of players can achieve when they decide to cooperate, regardless of the ...

A Shapley measure of power in hierarchies
(Elsevier, 2016-12)
A method for measuring positional power in hierarchies is proposed. Inspired by models of cooperative TU-games with restricted cooperation, such as permission structures, we model hierarchies by means of a certain kind of ...

Fuzzy restrictions and an application to cooperative games with restricted cooperation
(Taylor and Francis, 2017-05)
The concept of restriction, which is an extension of that of interior operator, was introduced to model limited cooperation in cooperative game theory. In this paper, a fuzzy version of restrictions is presented. We show ...
