Sharing profits in formal fuzzy contexts
(Elsevier, 2023-08)
Cooperative game theory is concerned with situations where a group of agents coordinate their actions to get a common benefit. An allocation rule for these situations is a way to share the common benefit among the agents. ...

The cg-average tree value for games on cycle-free fuzzy communication structures
(Sociedad Española de Estadística e Investigación Operativa, 2019)
The main goal in a cooperative game is to obtain a fair allocation of the profit due the cooperation of the involved agents. The most known of these allocations is the Shapley value. This allocation considers that the ...

Rough Shapley functions for games with a priori unions
(Taylor and Francis, 2023)
A family of allocation rules for cooperative games with a priori unions is introduced in this paper. These allocation rules, which will be called rough Shapley values, are extensions of the well-known Shapley value for ...

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 ...

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 ...

Soft cooperation systems and games
(Taylor and Francis, 2018-04)
A cooperative game for a set of agents establishes a fair allocation of the profit obtained for their cooperation. In order to obtain this allocation, a characteristic function is known. It establishes the profit of each ...

Games on concept lattices: Shapley value and core
(Elsevier, 2015)
We introduce cooperative TU-games on concept lattices, where a concept is a pair (S, S′ ) with S being a subset of players or objects, and S ′ a subset of attributes. Any such game induces a game on the set of players/objects, ...

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 distance in graphs
(Elsevier, 2018-03)
A new distance in finite graphs is defined through a game-theoretic approach. This distance arises when solving the problem about the fair cost, for a node in a graph, of attaining access to another node. The distance ...
