WebMany heuristics exist for the single-item dynamic lot-size problem, for example, the Silver-Meal, the part period balancing and a simple variant of the part period balancing. The worst case performances of these heuristics have been shown to be zero, 1/3 and 1/2 respectively. These heuristics can be generalized to the
