The accurate selection of a processing plant site can result in decreasing total mining cost. This problem can be solved by multi-criteria decision-making (MCDM) methods. This research introduces a new approach by integrating fuzzy AHP and gray MCDM methods to solve all decision-making problems. The approach is applied in the case of a copper mine area. The critical criteria are considered adja...

The main purpose of this paper is to present a fuzzy multi-criteria decision making (FMADM) model for appropriate location selection of a health center. Therefore, we identify sixteen criteria and sub-criteria for selecting a health center location. These criteria and sub-criteria have been obtained from literature reviews and practical interviews. This paper proposes a method which combines th...

The PROMETHEE is a significant method for evaluating alternatives with respect to criteria in multi-criteria decision-making problems. It is characterized by many types of preference functions that are used for assigning the differences between alternatives in judgements. This paper proposes a preference of green suppliers using the PROMETHEE under the usual criterion preference functions. Comp...

the use of value engineering (ve) methodology in construction industry has grown significantly, mainly in view of its extensive benefits. the main task in evaluation phase of ve workshop is to assess alternative ideas, proposed for each function. this phase of ve, hence, could be deemed as a multi criteria decision making (mcdm) problem. this paper presents a fuzzy decision support system (dss)...

Most of data in a multi attribute decision making (MADM) problem are unstable and changeable, and thus sensitivity analysis can effectively contribute to making proper decisions. Here, we offer a new method for sensitivity analysis of multi-attribute decision making problems so that by changing one element of decision making matrix, we can determine changes in the results of a decision making p...

An important phase of human resource management is personnel selection, which is concerned with identifying an individual from a pool of candidates suitable for a vacant position. As with many decision problems, personnel selection problem is very complex in real life. Some of the techniques in decision making are multi criteria decision making (MCDM) which can be applied for personnel selectio...

Decision making in an uncertain environment is a complex task for decision makers. Fuzzy multi criteria decision making methods are proposed in the literature where the subjective criteria and the weights of all criteria are assessed in linguistic variables since conventional methods cannot take into consideration the subjectivity and uncertainty in the decision process. Fuzzy ELECTRE I (Elimin...

Multiple criteria decision making (MCDM) is one of the most important fields of management science. It is related to several different goals or criteria that are to a certain extent in conflict with each other. The purpose of the decision making is to find the best or the most desirable alternatives. The complexity of the decision-making problem makes it impossible for a single decision maker t...
