THE EFFECTS OF APPLYING OBJECTIVE CRITERIA WEIGHT DETERMINATION IN TRACTOR SELECTION

Abstract

In this paper, the authors used multi-criteria decision-making to select among the offered types of tractors with the aim of determining the possible effects of certain weight coefficients on the final ranking of alternatives. For the purpose of determining the weights of the given criteria, three objective decision-making methods were used (Entropy, MEREC, and CRITIC), while the MABAC (Multi-Attributive Border Approximation Area Comparison) method was used for the final ranking. The results of the research show that different weights were obtained for individual criteria, but this did not significantly affect the choice of the best alternative. In all three cases of objective criteria evaluation, the X8 660 tractor was the best alternative in the final ranking. The results are important as they confirm the effective use of the mentioned methods. However, future research should compare these methods with a group of subjective methods to make the final decision in this field as rational as possible.
