Financial mangers bave to make decisions Ilnder many restrictions and often have to deal with vague and imprecise information. In multicriteria problems, the best solution is sought in a set X of alternatives under certain constraints with rates of contentment,ili : X ~ [0,1]. Considering these rates as membership fnnctions, the tools that fuzzy logic provides Is adeqll3te to solving a multicri...

In this paper, we consider the problem of bus selection for public transportation using a hybrid multicriteria decision making approach. The problem includes several conflicting factors which are economic, social, and technological factors. The integrated approach brings the flexibility of fuzzy AHP and simplicity of fuzzy VIKOR methodology together. To demonstrate the applicability of the meth...

Any decision is closely linked to the quality and availability of information. Innovative methodologies are proposed to help decisions based on imperfect information provided by more or less reliable and conflicting sources in uncertain context. These methods combine new uncertainty theories and multicriteria decision making. The ER-MCDA methodology associates the Analytic Hierarchy Process (AH...

Neutrosophic set is a powerful general formal framework, which generalizes the concept of the classic set, fuzzy set, interval valued fuzzy set, intuitionistic fuzzy set, and interval-valued intuitionistic fuzzy set from philosophical point of view. However, it will be difficult to apply in real science and engineering areas, while a simplified neutrosophic set (SNS) is a subclass of a neutroso...

The composition of fuzzy relations for their uniting in multicriteria decision making problems is considered. Some criteria evaluate a set of alternatives by fuzzy preference relations. The comparison between the criteria importance is given as a fuzzy preference relation too. Aggregation of these relations is made with the help of a composition of the couple of the relations by the criteria an...

A novel approach, based upon fuzzy logic and frames, for the creation of fuzzy expert shell is being proposed in this paper. The fuzzy logic effectively deals with the type of communication normally used by humans, whereas the frames have been used to store the correlated information in the form of a block. This shell uses a local inference mechanism within the frame with the help of a multicri...

with the complexity and amount of information in a wide variety of comparative performance reports in poultry production, making a decision is difficult. this problem is overcomed only when all data can be put into a common unit. for this purpose, five different decision making analysis approaches including  maximin, equally likely, weighted average, ordered weighted averages and technique for ...
