چکیده
A comparison is made between the most commonly used decision-making method (AHP), and two methods developed by the authors (APM and CSM). It is shown that the newly developed methods do not change the correlations and types of inequalities between the global priorities of the alternatives when the number of alternatives changes. This differentiates them from the AHP, which does change them. Also, unlike the AHP, which uses pair comparison matrices of criteria relative to goals and alternatives, the developed methods use the creation of pair-comparison matrices of criteria relative to alternatives and of alternatives relative to criteria. In order to obtain a result, it is enough to perform an expert analysis of all the alternatives and one criteria, or otherwise of all the criteria and one alternative. The other pair-comparison matrices are obtained either from the conditions of inverse symmetric matrices, or from the proportionality of weight correlations. The results of the developed methods fully coincide.

متن کاملComparison of FAHP and FANP Decision-Making Methods in Determining the Appropriate Locations for Constructing an Underground Dam for Water Harvesting
The recent droughts in Iran made a decline in groundwater table and the migration of villagers to cities was hindered supplying drinking water for the current population. Therefore it should be considered as an important issue. In this regard, it is possible to achieve this goal by constructing underground dams that recently have been suggested to replace by medium and small overland dams. The ...
متن کاملHorizontal representation of a hesitant fuzzy set and its application to multiple attribute decision making
The main aim of this paper is to present a novel method for ranking hesitant fuzzy sets (HFSs) based on transforming HFSs into fuzzy sets (FSs). The idea behind the method is an interesting HFS decomposition which is referred here to as the horizontal representation in the current study. To show the validity of the proposed ranking method, we apply it to solve a multi-attribute decision-making ...
