SOLVING DUAL FULLY FUZZY LINEAR SYSTEM BY USE FACTORIZATIONS OF THE COEFFICIENT MATRIX FOR TRAPEZOIDAL FUZZY NUMBER

Abstract

This article discusses the solution for a dual fully fuzzy linear system in the form of ˜ A˜x˜b = ˜B ˜x ˜ d is then transformed into the form ˜ A ˜x = ˜B
˜x ˜ f. Then the coefficients of the matrix A˜ and C˜ each of us form into a factorization of LU and then we will construct a simple algorithm to solve the system
