In such a design assessment process, different criteria need to be evaluated, which can be of both of a quantitative and qualitative nature, and the knowledge provided by experts may be vague and/or incomplete. The overall evaluation is based on a hierarchical analysis of a state’s nuclear activities on the basis of the IAEA physical model. Furthermore, the steps of the proposed interval-valued fuzzy group decision model are implemented to an application case from the recent literature of the FMS scheduling. SAGE remains majority owned by our founder and after her lifetime will become owned by a charitable trust that secures the company’s continued independence. www.sagepublishing.com, This item is part of JSTOR collection Recognize that a number of solutions used in previous decisions may be an innovation for the choice you are trying to make now.Here are three categories to consider when looking for known decision alternatives: 1. Safety is not only an eternal topic in coal mining but also is fundamental in the process of coal mine production, so it is important to establish a scientifically justified evaluation system and aggregate the decision information with the linguistic values. This paper presents a novel method for multiple attribute decision making problems, in which interval numbers are used to assess the weights of attributes, and fuzzy linguistic variables are utilized to evaluate the suitability of alternatives versus various attributes. As-, representative of radar signals is transformed into a. fuzzy multi-criteria decision making problem. All Rights Reserved. According to Proposition 7, we adopt the following method to understand why, The proposed algorithm for fuzzy group decision-, weighted difference of membership values between, In this section, we use two examples to illustrate the, proposed method for handling fuzzy group decision-, of the weighted difference of membership val-, average operator to aggregation element of equi, of them is more representative of radar signals. Decision-making is the process of identifying and choosing alternatives based on the values, preferences and beliefs of the decision-maker. Then the linguistic 2-tuple that expresses the equiv-, usual rounding operation, ordering of linguistic in-, formation is processed by the linear ordered struc-, ture of linguistic values, and its natural number in-, dexes is used to explain the ordering, which can be, expressed as follows: for any 2-tuple linguistic val-, on the above mentioned ordering, any decision re-, sults represented by 2-tuple linguistic values is or-, dered, and the best alternative for the experts can be, tuitionistic fuzzy sets, Li developed a methodology, for solving multiattribute decision making problems, cision results are represented by intuitionistic fuzzy, sets, and ordering is depended on score and accuracy, Recently, Chen and Niou proposed a method for, fuzzy multiple attributes group decision-making, in which, evaluation values and decision results are, represented by fuzzy sets on a finite and ordered lin-, ture about decision making problems, ranking meth-, ods are an important aspect to select the best alterna-, ation in a decision making problem correspond with. In the end, the corresponding conclusions about interval-valued fuzzy sets can be obtained similarly. Firstly, we propose the unbalanced linguistic weighted geometric operator, which can be used to deal with aggregation of unbalanced linguistic values with numerical weights. By ranking the defuzzification values of effective fuzzy synthetic ratings of alternatives, the best alternative selection can be determined. Generally, ordering is an important method to. In this paper, we analyze some algebraic properties of a kind of ranking method in fuzzy multiple attributes group decision-making, and prove that the ranking method is pre-ordering, its'drawback in fuzzy decision making is no unique alternative to be best alternative.
