This paper puts forward the concept of incentive utility, which converts value each attribute in multi-attribute decision-making into a unified index for measurement, thus simplifying decision-making. In this paper, comprehensive evaluation model based on TOPSIS utility is established. Through establishment index, and calculation ideal point disadvantage "ideal not ideal" overcome. It can bette...

the concept of  -semihyperring is a generalization of semiring, a generalization of semihyperring and a generalization of      -semiring. since the theory of ideals plays an important role in the theory of  - semihyperring, in this paper, we will make an intensive study of the notions of noetherian, artinian, simple and   regular      -semihyperrings. the bulk of this paper...

in this paper a fuzzy analytical network process model for supporting the vendor selection process in strategic situations is suggested. first, the vendor evaluation problem is putting together by use of the multi-criteria decision-making (mcdm) approach and a five-step hybrid process, which incorporates the technique of fuzzy analytical network process. then the modified topsis (technique for ...

the aim of this paper is to introduce and study set- valued homomorphism on lattices and t-rough lattice with respect to a sublattice. this paper deals with t-rough set approach on the lattice theory. the result of this study contributes to, t-rough fuzzy set and approximation theory and proved in several papers. keywords: approximation space; lattice; prime ideal; rough ideal; t-rough set; set...

The article is devoted to the problem of multi-criteria decision making. As application used equipment selection problem. analysis existing methods for solving this given. a method fuzzy TOPSIS (The Technique Order Preference by Similarity Ideal Solution) proposed. This based on ideal solution approach. issues practical implementation are discussed in details. results test at all stages present...
