![]() Decisions on the basis of multiple criteria are gaining in popularity, and the application of this method can be found in various areas of the public and private sectors. We can also state that the degree of concurrence in the order of application of the TOPSIS technique, in combination with both approaches expressed by the Jaccard index, is relatively low.Īt a time of increasing global competition, which we do not identify as just the 21 st century, it is necessary to pay increasing attention to the effective expenditure of funds or the identification and selection of alternative sources. ![]() ![]() The obtained results indicate that the order of the assessed subject (alternative) is not directly influenced by the method of determining the variability of the assessed criteria. The goal of the presented research is to quantify the differences (symmetry) in assessment using selected MCDM methods (Technique for Order of Preference by Similarity to Ideal Solution–TOPSIS), while applying an absolute and relative variability of the assessed criteria to a determination of their importance. The issue of which of these should be favoured during their use involves a specification of the importance of the assessed criteria. Selection of a suitable solution on the basis of this data represents a problem that multi-criterial methods (MCDM) are applied to. In the real world, acceptance of a decision is conditional on the availability of a great volume of data.
