| الملخص: | Title screen Multidimensional ordinal measurement in aform of problem of a single consensus rankingdetermination for m rankings of n alternatives is consideredin the paper. The Kemeny rule is one of deeply justifiedways to solve the problem allowing to find such a linearorder (Kemeny ranking) of alternatives that a distance(defined in terms of a number of pair-wise disagreementsbetween rankings) from it to the initial rankings is minimal.But computational experiments outcomes show that theapproach can give considerably more than one optimalsolutions what argues instability of the measurementprocedure. Hence, special efforts to avoid this phenomenonare needed. |
