In this paper we consider the familiar bin-packing problem and its ass
ociated set-partitioning formulation. We show that the optimal solutio
n to the bin-packing problem can be no larger than 4/3[Z(LP)], where Z
(LP) is the optimal solution value of the linear programming relaxatio
n ration of the set-partitioning formulation. An example is provided t

worst-case bound on the performance of the well studied First Fit Decr
