THE EFFECT OF DRAZIN INVERSE IN SOLVING SINGULAR DUAL FUZZY LINEAR SYSTEMS

The dual fuzzy linear system A˜x = B ˜x + ˜y where A, B are bothcrisp matrices, ˜x and ˜y are fuzzy vectors is called a singular dual fuzzy linearsystem while the coefficients matrix of the extended linear system of it be acrisp singular matrix. In this paper, on the solving the singular dual fuzzylinear system using Drazin inverse is discussed

Keywords:

Fuzzy number, Dual fuzzy system, Drazin inverse Singular matrices,
