Alternatywna metoda określania preferencji decydenta w zagadnieniach wielokryterialnych / Alternative methods of decision-maker preferences identification in multicriteria issues

Subject and purpose of work: The aim of this work is to present the application possibilities of ECONOMIC AND REGIONAL STUDIES STUDIA EKONOMICZNE I REGIONALNE ISSN 2083-3725 Volume 14, No. 2, 2021 ECREG STUDIES Vol. 14, No. 2, 2021 the weights of criteria is proposed, which maximizes the similarity of the final ranking to the other ones. Materials and methods: PROMETHEE II method and taxonomic measure were used to create rankings of exchanges. Hierarchical clustering combined with the k-means algorithm www.ers.edu.pl PDF OPEN ACCESS eISSN 2451-182X available data published on the Internet were analysed. Results: There was a high consistency in the ordering of exchanges when a multi-criteria and a multi-dimensional approach were used. Four groups of exchanges with a similar level of the values of net flows were identified. Exchanges in group one were characterized by the highest average net flows. Conclusions: The multi-criteria approach can be used as an alternative to the multi-dimensional assessment of cryptocurrency exchanges. The proposed simulation method for determining the weights of criteria can be helpful in case the researcher has no information about the importance of the criteria.

Subject and purpose of work: The aim of the work is to present and compare the results of selected procedures for assessing linear ordering methods. The considerations were carried out on the example of taxonomic measures of the security of cryptocurrency exchanges. Materials and methods: Publicly available data published on internet portals were used to assess the security of cryptocurrency exchanges. Composite indicators were created using the standardized sum method. The selection of the final representative was made on the basis of the similarity of rankings, the choice of the measure from the so-called efficient frontier, aggregate measure of the correctness of linear ordering methods and the PROMETHEE II method. Results: According to the values of all selected composite indicators, the Gemini exchange was the best in terms of the adopted criteria. Conclusions: Each of the analyzed procedures for selecting the final linear ordering method has its own logic, advantages and disadvantages.
