Reorder Levels for Lumpy Demand
T. M. Williams
Abstract
If demand for a product occurs in a few large orders, classical techniques are not suitable for setting the reorder level. When gamma-distributed sized orders arrive stochastically, with usually no more than one during a lead-time, approximate expressions for the optimum reorder level and resulting expected stock-out are derived. Experimental results suggest that this is a good approximation.
