Solution of different multi-criteria decision making engineering problems by PROMETHEE II and VIKOR

Abstract

In our day to day life we come across situations in which we have a number of choices available in front of us and it is difficult to choose among them on the basis of a single criterion. Different alternatives have different attributes related to them so it is important for the decision maker to weigh all the alternatives and come up with a common index on the basis of which he can compare his alternatives. Here in this thesis, to encounter with such problems, multi criteria decision making methods have been used to come up with the best alternative. Two methods namely PROMETHEE II (preference ranking organization method for enrichment evaluation) and VIKOR (višekriterijumsko kompromisno rangiranje) have been used to solve different engineering problems ranging from selection of machining parameters to choosing a supplier for an industry. PROMETHEE II uses the outranking method for the ranking of alternatives and VIKOR is a compromise solution method. Problems have been solved by both the methods and the results have been compared with each other.
