There is no doubt that the Analytic Hierarchy Process is in itself a remarkable contribution to the field of decision making.  In this paper, I have tried to point out what I consider to be Tom Saaty’s three most important contributions within his Analytic Hierarchy Process: group decision making, conflict resolution and the fundamental equation of pairwise comparisons.  The third contribution occupied him most of his life in an attempt to connect pairwise comparisons with brain activity related to cognitive processes.
