Abstract

The measurement of consensus and discrepancy among groups of evaluators is an important issue in group decision systems. These measurements will enable us to analyze the effort that should be made to obtain closer positions among subgroups. This paper presents a new approach, on the basis of the absolute order-of-magnitude qualitative model, to decision-making problems. The concepts of qualitative distance and entropy are defined in the framework of the distributive lattice of qualitativizations over a set of magnitudes or features.
