At present, complex evaluation of medical devices is very topical. The methods of pharmacoeconomics and cost analyses appear to need some modifications caused by a different character of medical devices [1]. One of the approaches to this task is utilization of multi-criteria decision making [2]. In this study, a methodology for medical devices evaluation is suggested based on the multi-criteria...

This paper considers two distinct procedures to lexicographically compose multiple criteria for social or individual decision making. The first procedure composes M binary relations into one, and then selects its maximal elements. The second procedure first selects the set of maximal elements of the first binary relation, and then within that set, chooses the maximal elements of the second bina...

This study is intended to improve the lack of recruitment processes as well as reduce individual senses of supervisory level by fuzzy logic and Analytic Hierarchy Process methods. This study tries to identify appropriate personality traits and key professional skills through the information statistics and analysis of Analytic Hierarchy Process in order to expect the recruitment process be more ...

  Multiple criteria decision making (MCDM) problem is one of the famous different kinds of decision making problems. In more cases in real situations, determining the exact values for MCDM problems is difficult or impossible. So, the values of alternatives with respect to the criteria or / and the values of criteria weights, are considered as fuzzy values (fuzzy numbers). In such conditions, th...

one of the most important steps involved in mining operations is to select an appropriate extraction method for mine resources. after choosing the extraction method, it is usually impossible to replace it with another one because it may be so expensive that implementation of the entire project could be economically impossible. choosing a mining method depends on the geological and geometrical c...

the expansion of major cities regardless of the scientific planning principles has led to theemergence of negative urban development impacts in iran such as the degradation of natural resources andvarious forms of pollution. undoubtedly, urban rivers can enhance the ecological value of the earth to anoptimal extent. however, to benefit from these potentials, appropriate planning looks inevitabl...

Deriving efficient variants in complex multiple criteria decision making problems requires optimization. This hampers greatly broad use of any multiple criteria decision making method. In multiple criteria decision making Pareto sets, i.e. sets of efficient vectors of criteria values corresponding to feasible decision alternatives, are of primal interest. Recently, methods have been proposed to...

Multiple attribute decision-making theory under uncertainty is an important part of decision making theory. In this paper, by using optimal plan, the optimization weight model is established. Then, based on formulas of possibility degree, a new attribute decision making approach is proposed to study multi-criteria decision making problems under uncertainty in which criteria values are interval ...

The increasing complexity of decision making in a severely dynamic competitive environment of the universe has urged the wise managers to have relevant strategic plans for their firms. Strategy is not formulated from one criterion but from multiple criteria in environmental scanning, and often, considering all of them is not possible. A list of criteria utilizing Delphi was selected by consu...

Sourcing addresses critical decisions of what to buy, how much to buy, whom to buy from, and how to manage relationship with suppliers. Decision making in sourcing can involve a few hundred offerings each of which is described by several dozen attributes. When using traditional decision analysis techniques, sourcing specialists are often having difficulties in assigning appropriate weights to a...
