Vlse Criterion Optimization and Compromise Solution in Serbian (VIKOR)

Abstract

From the Serbian language, VIsekriterijumska optimizcija i KOmpromisno Resenje (VIKOR) is a way of finding a compromise ranking created by Serafim Oprikovic. VIKOR is a method that determines the superior value in comparing two alternatives for a final set of other actions that must be ranked and selected between the criteria, and resolves a discrete multicriteria problem with disparate and conflicting aspects. VIKOR pays more attention to demanding and choosing one of the best from the set of variables and determines compromise difficulties with conflicting aspects that can help decision makers to show the best alternative. A compromise conclusion is the final conclusion among the alternatives, closer to ideal solution. The VIKOR and TOPSIS methods are based on distance calculation to ideal solution of the decision matrix, but the compromise solution in VIKOR is guided by mutual concessions, while in TOPSIS the best conclusion is guided by the minimum distance from positive ideal solution (PIS) and the farthest distance from negative ideal solution (NIS). PIS is considered to be a type that consists of the best ratings between all considered criteria or attributes. On the other hand, NIS is considered a candidate that does not contain the best ratings between all the criteria considered. In this study the detailed information of the VIKOR technique will be presented.
