Abstract: Analytical relationships were obtained for the chances of preference of the compared objects within pairs of fuzzy polyinterval alternatives of different localization as well as the associated risks. Collective risk estimating method is used in the work to compare the alternatives. The obtained results are of independent importance and also supplement the relationships established earlier for comparing fuzzy polyinterval alternatives with using the “mean-risk” method. This makes it possible to use a multimethod complex approach for comparing polyinterval objects that increases the validity of the comparison results.

Keywords: pairwise comparison of fuzzy polyinterval alternatives, collective risk estimating method, analytical relationships for calculating chances of preference and risks.
