This paper presents an approach for comparing the results of Web service rankings based on quality characteristics obtained using the multi-criteria decision-making method, Logic Scoring of Preference (LSP), with rankings obtained using several popular methods. Formulas were derived to calculate the sensitivity of the LSP composite aggregator to input criteria for the considered Web service selection problem. Sensitivity estimates were used to determine a rational range of changes in the values of input quality attributes when comparing the ranking results. Consistency measures and coefficients that consider the position of alternatives in the list of ranks were used to compare rankings. The obtained formulas and measures for comparing rankings were demonstrated through numerical experiments.
