Fuzzy approximate solution of general fully fuzzy linear systems based on GLR-fuzzy numbers

In this paper, a general m×n fully fuzzy linear systems **** is studied by using the GLR-fuzzy numbers. A sufficient condition for the solution being a non-negative (non-positive) fuzzy approximate solution or a strong (weak) fuzzy approximate solution is provided. Moreover, the fuzzy approximate general solution to FFLS(2) is obtained based on the generalized inverses of matrix. An example is presented to illustrate the proposed results.
