Note—Optimal Inventories Based on Job Completion Rate for Repairs Requiring Multiple Items
构建了一个多项目库存优化模型，以持有成本和维修工作不因缺货而中断的概率为目标，发现最优策略与标准边际分析解形式相同。
A model is formulated for optimizing multi-item inventories for repair of field equipment based on holding costs and the probability of job completion without stockout. This results in a different type of objective function from those found in most inventory problems in that the contributions of different line items are not separable. It is shown, however, that the optimal policy has the same form as the one that results from standard marginal analysis solutions in which the objective function is separable.
