The article discusses the problem of solving a fully fuzzy linear system of equations with a fuzzy rectangular matrix and a fuzzy right-hand side described by fuzzy triangular numbers in a form of deviations from the mean. A solution algorithm based on finding pseudo-solutions of systems of linear equations and corresponding software is formed. Various examples of created software application for arbitrary fuzzy linear systems are given.

Keywords: fuzzy numbers, fully fuzzy linear system of equations, triangular numbers, pseudo-inverse matrix, pseudo-solution

Column: Numerical Methods
