Abstract In this paper we have investigated a fuzzy linear programming problem with fuzzy
quantities which are LR triangular fuzzy numbers. The given linear programming problem is
rearranged according to the satisfactory level of constraints using breaking point method. By
considering the constraints, the arranged problem has been investigated for all optimal solutions
connected with satisfactory level of quantities on all intervals that constituted from breaking points of
the constraints. Optimal solution could be obtained on the constructed [ p-1 , p] intervals for
p=1,2… Here the fuzzy primal simplex algorithm is designed based on revised TSAO’s ranking
method.
