The purpose of this paper is to propose an interactive method, which is designed to select the optimal preferred alternative for the MLDM(Multiple-the Larger-the better type Decision-Making) proble- ms with the-larger-the-better quality characteristics. The basic idea of the paper is essentially to eliminate inefficient alternative based on the concept of Taguchi Signal-to-Noise Ratio and the cutting range instead of using UVF(Utility/Value Function) on the group of attributes that can be considered importantly by the decision makers. As a result, the method proposed in the paper for MLDM problems can be significant in that the change of characteristics is transformed into the size of Signal-to-Noise Ratio, which can be relatively easy to understand by decision makers.
