A method for solving fully fuzzy linear system

Abstract

In this paper, a numerical method for nding minimal solution of a m n fully<br />fuzzy linear system of the form Ax = b based on pseudo inverse calculation,<br />is given when the central matrix of coe cients is row full rank or column full<br />rank, and where A~ is a non-negative fuzzy m n matrix, the unknown vector<br />x is a vector consisting of n non-negative fuzzy numbers and the constant b is<br />a vector consisting of m non-negative fuzzy numbers.
