An Introduction to Fuzzy Inference in Economics

Whenever decision makers are confronted with probabilistic uncertainty and imprecise information, inference methods which claim crisp inputs may not be used efficiently. Fuzzy inference is a new and promising inference approach, which can internalize fuzzy information in an inference procedure. The purpose of this paper is to give an introduction to techniques of fuzzy inference for applications in economics. By using methods of fuzzy inference, it is shown how to infer a conclusion from a set of fuzzy if-then rules and one or more conditions.
