The sensitivity analysis for multi-attribute decision making (MADM) problems is important for two reasons: First, the decision matrix as the source of the results of a decision problem is inaccurate because it sorts the alternatives in each criterion inaccurately. Second, the decision maker may change his opinions in a time period because of changes in the importance of the criteria and in the ...

Purpose This paper proposes a new multi-criteria decision-making method, called the vital-immaterial-mediocre method (VIMM), to determine weight of multiple conflicting and subjective criteria in problem. Design/methodology/approach The novel utilizes pairwise comparisons, vector-based procedures scoring approach weights criteria. VIMM compares alternatives by three crucial components, namely v...

Choosing the best option out of many available options is always goal to be achieved in all areas. However, parameters (criteria) each alternative are not same, sometimes contradictory. In this situation, choosing an extremely difficult decision for maker. Multi-criteria making (MCDM) ranking alternatives based on criteria alternative. More than one hundred multi-criteria decision-making method...

in most of the multi-criteria decision making problems, it is important to have necessary information about relative importance of each criteria. in this group of problems, weights measure the relative importance of preferences of each criteria in comparison with the other decision making criteria. in this research, the nise method has been used for mapping mean-variance efficient frontier. nis...

in the process of investment decision making, next to financial indicators many other aspects of investment projects are increasingly often considered. this leads to the multi-criteria evaluation of a project. the advantage of multi-criteria methods is the ability to take into account all (not only financial) aspects of the attractiveness of an investment project. the selection of criteria of p...
