Invers dan General Invers Untuk Matriks Bilangan Fuzzy Trapezoidal
This thesis discusses the inverse and general inverse of a trapezoidal fuzzy number matrix. Suppose u = (a, b, α, β) an arbitrary trapezoidal fuzzy number which is converted into fuzzy intervals to determine the mean or m(u) of the fuzzy number. The middle value is used to construct the arithmetic of multipli-
Furthermore, the constructed arithmetic is used to determine the inverse of the trapezoidal fuzzy matrix using the elementary row operation method which pro- duces U U −1 = I and to determine the general inverse of the trapezoidal fuzzy matrix.
Keywords: Trapezoidal fuzzy number, arithmetic of fuzzy number, Inverse method and Generalisized Inverse
