Fuzzy relational equations: Bridging theory, methodology and practice

This study delivers a general overview of the theory and practice of fuzzy relational equations. We discuss various methods leading to the solutions o f these equations starting from analytical approaches, moving through semi- analytic methods and finally elaborating on the neural-like style of findin g solutions to relational constructs. The paper addresses important aspects of knowledge representation worked out by these equations and proposes a n umber of structural enhancements of the existing relational architectures.
