Statistical Comparison of the Evaluation Process Results of Location Alternatives in Case of Flat and Hierarchy Structure of Criteria

Abstract

The main directions in this research are focused mainly on the peculiarity and nature of the decision-making process. The desire is to develop and improve a multi-criteria approach to solve logistics and many real problems. The most common issues in the standard multi-criteria decision-making (MCDM) technique are obtaining criteria weights, the possibility to work with a large number of criteria and alternatives and ranking and selecting the most desirable alternative. Generally, the produced ranks obtained by different techniques would have different levels of similarities. Kendall's tau-b was selected to analyse the similarities of the produced ranks by proposed approach in a case with a flat and hierarchy structure of criteria. The study demonstrates the robustness of the proposed approach by changing a criteria number and highlights the significance of sensitivity analysis in assessing the reliability of MCDM outcomes.
