General trust management model that we present is adapted for ad-hoc coalition environment, rather than for classic client-supplier relationship. The trust representation used in the model extends the current work by using the fuzzy number approach, readily representing the trust uncertainty without sacrificing the simplicity. The model contains the trust representation part, decision-making pa...

In 2011, Mallozzi et al. [Fuzzy Sets and Systems 165(2011) 98105] introduced a core-like concept (called F-core) and a balanced-like condition for games in which the worth of any coalition is given by means of a fuzzy interval. They proved that a balanced-like condition is necessary but not sufficient enough to guarantee the F-core to be non-empty. In this paper, we study deeply on this problem...

This paper deals with the design of scalable, fuzzy adaptive, decision making systems constructed from sets of heterogeneous classifiers. We propose a multiclassifier architecture formed by sparsely connected coalitions of classifiers. Coalitions are defined by fuzzy integral operators on small, but not necessarily disjoint, subsets of classifiers. The small size constraint on individual coalit...

Owing to the fact that payoff of grand coalition is limited players’ allocation, what more, other players will not satisfy with allocation scheme if one possible coalitions allocate too much. Based on this fact, it better pursuit all in are as close coalition’s possible. In contrast, far from payoff, lead instability coalition. To address issue, several linear programming models constructed for...

For the last decades, research studies have been developed in which a coalition of Fuzzy Sets Theory and Statistics has been established with different purposes. These namely are: (i) to introduce new data analysis problems in which the objective involves either fuzzy relationships or fuzzy terms; (ii) to establish well-formalized models for elements combining randomness and fuzziness; (iii) to...

The seminal contribution of Debreu-Scarf [4] connects the two concepts of core and competitive equilibrium in exchange economies. In effect, their core-equilibrium equivalence result states that, when the set of economic agents is replicated, the set of core allocations of the replica economy shrinks to the set of competitive allocations. Florenzano [6] defines the fuzzy core as the set of allo...

We consider capacities and games whose value v(S) depend on the organization of N \ S, this organization being represented by a partition. Hence we deal with capacities and games depending on two arguments: a subset (coalition) S and a partition π containing S. We call embedded coalition any such pair (S, π). We first provide a suitable structure for the set of embedded coalitions, study its pr...

Cooperative autonomous agents form coalitions in order to share and combine resources and services to efficiently respond to market demands. With the variety of resources and services provided online today, there is a need for stable and flexible techniques to support the automation of agent coalition formation in this context. This paper describes an approach to the problem based on fuzzy coal...
