Sensitivity analysis of the compromise variant to changes in weights within selected methods of Multicriteria evaluation of alternatives

This bachelor's thesis focuses on the sensitivity analysis of the compromise variant to changes in weights within selected methods of Multi-criteria Decision Analysis (MCDA), specifically the Weighted Sum Approach (WSA) and the Basic Variant Method. The main objective is to examine how changes in criterion weights affect the results and the final ranking of evaluated alternatives. To achieve this goal, an application was developed on the Excel platform using VBA, allowing the analysis of result sensitivity to changes in input parameter weights. The thesis includes a theoretical introduction to multi-criteria decision-making, a detailed description of the methods used, and an analysis of data obtained through application testing. It also provides an overview of the results, demonstrating how different weight settings can influence the final decision. Emphasis is placed on the practical use of the developed application and its potential to facilitate the decision-making process, thereby contributing to a better understanding of the importance of criterion weights in multi-criteria evaluation.
