我们考虑一个库存，其中每个物品都有一个具有已知分布的随机现场使用寿命，该分布以一种已知的确定性方式随时间变化。问题是对物品进行发放排序，目的是使总现场使用寿命最大化。在现场使用寿命分布的单调似然比假设以及分布随时间变化的凸性和凹性假设下，我们表明后进先出（LIFO）和先进先出（FIFO）策略具有很强的最优性性质。
We consider a stockpile in which each item has a stochastic field life with known distribution, this distribution changing in time in a known deterministic fashion. The problem is to order the items for issuance to the field with the objective of maximizing the total field life. Under monotone likelihood ratio assumptions on the field life distributions, and convexity and concavity assumptions on the change in time of the distributions, we show that LIFO and FIFO policies possess a strong optimality property.
