This paper proposes a method to solve the group decision making (GDM) problems with multi-granularity linguistic assessment information. In the method, the multi-granularity linguistic information provided by experts is firstly expressed in the form of fuzzy numbers. In order to make the collective opinion close to each expert’s opinion, a linear goal programming model is constructed to integra...

A comparative study of ranking river basin planning and development alternatives under a multi-criterion environment, including both qualitative and quantitative aspects using ELECTRE and RANFUW methodologies, is presented in this paper. The purpose is to find the most suitable planning for reservoirs with their associated purposes aimed at the sustained development of one of the major peninsul...

suitable supplier selection is the most important factor in supplier chain management; so that correct decisions in this phase, caused to reduce costs, make permanent relationship with suppliers and strong competitive strategy in market. in this paper, by reviewing the past articles, important related criteria found and then weighting of criteria and evaluation of alternatives were done with fu...

This paper suggests ranking alternatives under fuzzy MCDM (multiple criteria decision making) via an centroid based ranking approach, where criteria are classified to benefit qualitative, benefit quantitative and cost quantitative ones. The ratings of alternatives versus qualitative criteria and the importance weights of all criteria are assessed in linguistic values represented by fuzzy number...

In this paper, we present a model allowing to determine the weights related to interacting criteria. This is done on the basis of the knowledge of a partial ranking over a reference set of alternatives (prototypes), a partial ranking over the set of criteria, and a partial ranking over the set of interactions between pairs of criteria.

This paper deals with the problem of ranking several alternatives on the basis of a valued preference relation. A system of three independent axioms is shown to characterize a ranking method based on "net flows" which contains as particular cases the rules of Copeland and Borda and is used in one of the PROMETHEE methods. IIntroduction Suppose that you want to compare a number of alternatives t...

This paper considers the ranking problem of candidates for a certain position based on ballot papers filled by voters. We suggest a ranking procedure of alternatives using cooperative game theory methods. For this, it is necessary to construct a characteristic function via the filled ballot paper profile of voters. The Shapley value serves as the ranking method. The winner is the candidate havi...

Consider the problem of ranking social alternatives based on the number of voters that prefer one alternative to the other. Or consider the problem of ranking chess players by their past performance. A wide variety of ranking methods have been proposed to deal with these problems. Using six independent axioms, we characterize the fair-bets ranking method proposed by Daniels [4] and Moon and Pul...

In this paper we address the problem of nding the simulated system with the best (maximum or minimum) expected performance when the number of alternatives is nite, but large enough that ranking-and-selection procedures may require too much computation to be practical. Our approach is to use the data provided by the rst stage of sampling in a ranking-and-selection procedure to screen out alterna...

The purpose of this paper is to evaluate and select consulting firms by suggesting a centroid ranking approach based fuzzy multiple criteria decision making (MCDM) method, where ratings of alternatives versus qualitative criteria and the different importance weights among criteria are assessed in linguistic values represented by fuzzy numbers. Criteria are categorized to qualitative, benefit qu...
