Multi-Criteria Decision-Making (MCDM) is one of the most widely used decision methodologies in the sciences, business, and engineering worlds. MCDM refers to screening, prioritizing, ranking or selecting the alternatives based on human judgment from among a finite set of alternatives in terms of multiple usually conflicting criteria. In this paper, we develop a new methodology for solving multi...

objectives: this study aimed to evaluate and analyze the ergonomic behaviors order to select the best work shift group in an iranian petrochemical company, in 2010. methods: the methodology was based on the ergonomic behavior sampling (ebs), and performed using electre method. in this study 1147 behaviors were observed. results: the results indicated that 43.6% of workers’ behaviors were unergo...

AbstractThe purpose of this paper is to implement a methodology based on stakeholder’s judgment with assistance of fuzzy Multi-Criteria Decision Analysis (MCDA) methods to assess the environmental impact. Fuzzy Analytic Hierarchy Process (FAHP) is used as a multi-level decision-making tool taking into consideration human evaluation; it captures the vagueness in ordinal judgments obtained from s...

The former method starts by numerically estimating the adequacy and the inadequacy (with respect to the initial data) ofeach statement "the alternative i appears in on aggregate hierarchy on the j-th place* and constructs a preorder which maximizes the ratio of total sum of adequacy values by the total sum of inadequacy values for the associated hierarchy. The latter method involves usual conco...

<abstract><p>Many real-world decision-making issues frequently involve competing sets of criteria, uncertainty, and inaccurate information. Some these require the involvement a group decision-makers, where it is necessary to reduce various available individual preferences single collective preference. To enhance effectiveness multi-criteria decisions, popular technique that makes pr...

In this paper, the evaluation of customers’satisfaction is investigated by using group decision making method under uncertainty. Here, we have used the Zadeh’s fuzzy concept to model and measure the satisfaction. For this purpose, we have firstly applied the Delphi method with fuzzy Likert scales. Then, the fuzzy ELECTRE technique was used in order to ordering the index and questionnaires. For ...

OBJECTIVE The aim of this paper is to apply an informatics tool for dealing with a medical decision aiding problem to help infertile couples to become parents, when using assisted reproduction. METHODS A multiple criteria decision aiding method for sorting or ordinal classification problems, called Electre Tri-C, was chosen in order to assign each couple to an embryo-transfer category. The se...
