Abstract:

In this paper, we consider the effects of deteriorating inventory on lot-sizing in material requirements planning systems. Five existing heuristics were extended to address the single-level lot-sizing problem with deteriorating inventory and evaluated via a large-scale simulation study. Three factors were taken into consideration for the simulation study, namely, rate of inventory deterioration, percentage of periods with zero demand, and setup cost. Our computational results, undertaken within a wide range of experimental conditions, indicate that one of the modified heuristics exhibits the best overall cost performance. We also provide insights in regard to the cost performance behavior of the five modified heuristics.
