## Abstract

Supplier selection problem is a specific problem of linear programming. Consider two objective functions, the first objective function is a function that minimizes the total purchase price of sack and the second objective function is a function that maximizes the total quality. This problem is a special case of multiobjektif linear programming.Coefficient functions of the total price and quality function declared with TFNs (Triangular Fuzzy Numbers). Consider three companies suppliers, will be determined number of sack for buying minimum of 10,000,000 pieces from the three suppliers that minimize the total price and maximize total quality simultaneously. Multiobjektif fuzzy linear programming problems are transformed into a single objective deterministic problem using fuzzy set theory decision. Deterministic single objective problem solved by using Branch and Bound method. The solution of Branch and Bound method using software WinQSB.
