Cooperative fuzzy games arising from economic situations

E. Fukuda, S. Ishihara, S. Muto. Tokyo Institute of Technology

S. H. Tijs. Tilburg University

R. Branzei. Alexandru Ioan Cuza University

This paper deals with cooperative fuzzy games arising from two economic situations: a linear production situation and a labor-time availability situation. In both economic situations we derive cooperative fuzzy games and study conditions for nonemptiness of Aubin's core. Also, relations between reasona-ble (stable) payoff schemes for the economic situations and…

Multiobjetive evolutionary optimization for elman recurrent neural networks, applied to time series prediction

M.P. Cuellar, M. Delgado, M.C. Pegalajar. University of Granada

In previous works, we showed how Recurrent Neural Networks, trained with Genetic Algorithms, can achieve a good performance in Time Series Pre-diction problems. However, the problem of finding the optimal structure of the Network is still a tedious task, which requires several experiments and multiple tests. In this work, we…

A comparative analysis of the forecasting ability of classic econometric and fuzzy models

V. Profillidis, G. Botzoris. Democritus University of Thrace

The present paper analyzes the accuracy of forecasting ability that can be reached by the use of fuzzy techniques in comparison to classic econometric models. Following a brief presentation of the fuzzy technique, a revue of existing methods and models for forecasting rail passenger demand is presented. Based on data…

Models for analyzing purchase decision in consumers of ecologic products

L. Salgado Beltrán, A.M. Gil Lafuente. University of Barcelona

The consumer purchase attitude of product, in this case, an ecological product, can be marked by multiple factors. In this paper we pretend to obtain cause-effect relations that it takes to the consumers to make the decision of realize the purchase of these products. We apply a methodology based on…

Special lattice intuitionistic fuzzy sets and applications in management in non-profit organizations

A. Tepavcevic, A. Pešic. University of Novi Sad

A special kind of lattice valued intui-tionistic fuzzy sets is introduced and investigated. Connections with all the previously introduced definitions are shown. Properties of cut subsets are deduced. Hesitancy margin for such fuzzy sets is also introduced. Conve-nience of new notions in applications in management is demonstrated, in particular in…

Interval weights in AHP by Linear and quadratic programming

T. Entani. Kochi University

K. Sugihara. Fukui University of Technology

H. Tanaka. Hiroshima International University

Analytic hierarchy process (AHP) is proposed to give priority weights with respect to many items. The priority weights are obtained from the com-parison matrix whose elements are given by a decision maker as crisp numbers. We assume that the item's weights are intervals, because a comparison matrix based on human…
