Comparative analysis of multiattribute techniques based on cardinal and ordinal inputs

This paper compares multiattribute decision analysis under conditions of partial information and ordinal input. Difficult decisions based on partial information usually are dealt with through obtaining more precise input information. The purpose of this paper is to present a technique for systematically exploring the entire region within weight bounds established by ordinal input data. The centers of mass of the products of weights and utilities is used. Some consideration of sensitivity analysis for this problem is presented.
