Abstract :
A novel model based on the synergy of fuzzy multi-criteria group decision making technique and case-based reasoning is proposed for building a reliable rating system. Both fuzzy numbers and linguistic terms are applied for knowledge expression by experts. A measurement of knowledge validation is developed to evaluate the quality of experts´ judgments at a consistency level, which serves as a proper weight for achieving consensus in the knowledge integration process. Consequently, the obtained consensus reveals an ideal solution. Experimentation for fuzzy performance rating is presented to validate the proposed model.
