Modifying Weak Solutions of a Triangular Fuzzy Linear System to Strong Ones

Zengfeng TIAN


This paper is concerned with the structure of solution space of triangular fuzzy linear systems. The existence of non-triangular fuzzy number solutions for triangular fuzzy linear systems is proved. According to the structure of solution space, an approach of modifying a weak fuzzy number solution of the triangular fuzzy linear system to a strong solution is illustrated. Key Words: Fuzzy numbers; Solution space; Fuzzy linear system
