The ordinal consensus ranking problem with uncertain rankings
Result description
In the ordinal consensus ranking problem (OCRP) a set of k decision makers rank a set of n alternatives with regard to one overall criterion (or a set of criteria) from the 1st place to the nth place. The goal is to find a consensus ranking expressing anopinion of a group. The aim of this article is to present a model for OCRP solution with uncertain rankings. This approach is more suitable than classic approach with certain rankings, as the latter case doesn't allow for imprecise information or uncertainty often involved in real decision-making processes. In this paper uncertain ranking gij is defined as a decision maker's confidence that an alternative i is ranked at the jth position. In the model for OCRP solution with uncertain rankings generalized means operator is used for ranking aggregation and the final consensus ranking is obtained by the use of a binary dominance relation. The model can be extended to multiple criteria or different weights of decisi.
