Solution of interval valued fuzzy relation equation

Interval Valued Fuzzy Sets play a very important role in the fuzzy set theory. In this paper solutions of fuzzy relation equation x · A = b are studied, where A is an interval valued fuzzy m × n matrix, b is an interval valued fuzzy n-vector and the · operation is a Max-Min operation of matrices. The solution x is an interval valued fuzzy m-vector. Computer function scripts in MATLAB are developed to facilitate these computations. A survey was conducted by Rover Scouts of Bangladesh and one Solution to the fuzzy relation equation obtained in this research matches with the survey results.
