Paper: Rating and ranking of multiple-aspect alternatives using fuzzy sets

摘要: A method is proposed to deal with multiple-alternative decision problems under uncertainty. It assumed that all the alternatives in choice set can be characterized by a number of aspects, and information available assign weights these aspects construct rating scheme for various each alternative. The basically consists computing weighted final ratings alternative comparing ratings. uncertainty inherent assessments accounted considering variables as fuzzy quantities, appropriate membership functions. Accordingly, evaluation degree ranking first. practical given compute functions sets induced mappings, applied problem at hand. examples are worked out. compared another one Kahne who approaches probabilistically.
