A fuzzy inverse relation based on godelian logic and its applications

Fuzzy logic applicable to decision-making processes such as diagnostic expert systems and fuzzy controllers is the prime concern of this paper. In these applications, an inverse operation (or backward inference) plays an important role. In the current paper, a new backward inference technique based on Gödelian logic is proposed. The relation between the forward and backward inferences is established by introducing fuzzy joint and conditional relations.
