A Note on the Effect of Sudden Obsolescence on the Optimal Lot Size
探讨了传统上将过时成本计入持有成本的方法是否适用于需求寿命呈指数分布的物品，结论是该方法对突然过时的物品是合适的。
ABSTRACT In most management situations, the decision to hold inventory involves some element of obsolescence risk The traditional approach to this problem, in both theory and practice, is to incorporate obsolescence costs in the inventory holding cost. This note explores this issue and demonstrates that the traditional approach is appropriate for items subject to sudden obsolescence; that is, for items with demand lifetimes that are exponentially distributed.
