in this work, we define fuzzy soft ($fs$) matrices and theiroperations which are more functional to make theoretical studies inthe $fs$-set theory. we then define products of $fs$-matrices andstudy their properties. we finally construct a $fs$-$max$-$min$decision making method which can be successfully applied to theproblems that contain uncertainties.

E-businesses play a critical role in today's knowledge-based economies. Despite their ‎increasing portion, e-businesses experience high rates of failure. Therefore, it is of prime ‎importance to identify their decision-making activities encountering outer competitive forces ‎and their internal structural events. In this study, through using the Grounded Theory approach, we ‎analyze interviews c...

Abstract— In this paper, a new extended method of multi criteria decision making based on fuzzy-Topsis theory is introduced. fuzzy mcdm algorithm for determining the best choice among all possible choices when the data are fuzzy is also presented. Using a new index leads to procedure for choosing fuzzy ideal and negative ideal solutions directly from the fuzzy data observed alternatives.in this...

in this paper, a novel hybrid model based on neural network and game theory is proposed to support the analyzers in oil market. in this model, first the neural network is utilized to learn the oil prices associated with opec production level and usa imports level. then the learned neural network is applied by a game model. finally the nash equilibrium points of the game present the optimum deci...

The paper presents the author’s partial and personal historical reconstruction of how decision theory evolved to decision aiding methodology. The presentation shows mainly how “alternative” approaches to classic decision theory evolved. In the paper is claimed that all such decision “theories” share a common methodological feature which is the use of formal and abstract languages as well as of ...

rough sets theory is a mathematical approach for analysis of a vague description of objects presented by a well-known mathematician, pawlak (1982, 1991). this paper explores the use of rough sets theory in site location investigation of buried concrete water reservoirs. making an appropriate decision in site location can always avoid unnecessary expensive costs which is very important in constr...
