COMPENSATORY LOGIC: A FUZZY NORMATIVE MODEL FOR DECISION MAKING

Abstract

Fuzzy Logic is a convenient approach for decision making. Its capacity to incorporate verbal statements into formal modeling is advantageous for a systematic treatment of actual situations. This vantage comes from a proper interaction between decision-maker’s information and expert reasoning. Many revealing studies deal with multi-valued logics, covering the examination of a variety of operators. However, the real possibility of incorporating “expert knowledge” and the subjectivity inherent to decision makers in practical situations remains limited. This paper proposes an alternative axiomatic multi-valued logic system to
overcome such limitation. The system disregards the classical concepts of norm and co-norm. Existential and universal quantifiers are defined consequently, and propositional bivalent classic calculus is also introduced within the logical structure
