Generating consensus priority point vectors: a logarithmic goal programming approach

The analytic hierarchy process (Saaty, The Analytic Hierarchy Process: Plan ning, Priority Setting, Resource Allocation, New York: McGraw-Hill 1980) is a popular technique for addressing multiple-criteria decision-making probl ems (MCDMs). Various techniques have been proposed for using the AHP in gro up situations. Fundamental to the AHP is the generation of priority point v ectors from matrices of pairwise comparison data. In this paper, we present a logarithmic goal programming model for generating the 'consensus' priori ty point vector from the set of individual priority point vectors. (C) 1999 Elsevier Science Ltd.
