AN APPROACH TO USING THE ANALYTIC HIERARCHY PROCESS FOR SOLVING MULTIPLE CRITERIA DECISION-MAKING PROBLEMS

In this paper we present a procedure for solving multiple criteria decision making problems. Our procedure, which is an extension of the Analytic Hierarchy Process, addresses the issue of fuzziness in the weighing information provided by the decision maker, the consequent stability of the AHP ranking of the alternatives and the sensitivity of such rankings to small perturbations. These issues are especially important when the concept of optimality incorporates parameters or weights that reflect subjective preferences. The procedure provides a consistent and systematic method for carrying out goal-seeking sensitivity analysis that captures the decision maker's preference structure using his/her indifference region.
