Fuzzy Structural Modeling using Repertory Grid based on FISM/fuzzy

Abstract

Fuzzy Structural Modeling is a problem of how to efficiently fill the fuzzy reachability matrix. To do it effectively, there are needs to supports of eliciting a set of elements and generating a fuzzy relational matrix. In this paper, support-methods with a repertory grid for generating the fuzzy reachability matrix are proposed. First, an algorithm of generating a fuzzy matrix from a repertory grid is proposed. Use of the repertory grid help the user to recognize important factors in his problem domain. Second, an algorithm to make a fuzzy reaczhability matrix from a user's fuzzy matrix using the transitive inconsistency is proposed. The algorithm makes a structural model that is not different from user's model. Use of the methods makes it possible to do a flexible and an efficient modeling for complex and fuzzy systems.
