A critical problem in decision analysis is how to evaluate the difference between two or more different rankings of a set of alternatives. In this paper it is assumed that a group of decision makers has already established a ranking for each one of a set of alternatives. Then, the problem examined here is how to evaluate the differences among these rankings. This problem does not have a unique solution and thus we consider a number of alternative approaches. The analysis presented here illustrates that this problem is not trivial and, moreover, it is associated with many counter-intuitive issues.

Key Words:
Decision analysis, ranking of alternatives, combinatorics, conflict resolution, group decision making.
