主讲提纲：

1. To fill this gap, we formulate the problem as a two-stage Markov Decision Process (MDP), where component substitution and inventory replenishment decisions are made in the first and second stages, respectively.

2. We will show that under a mild increasing component inventory level condition, the optimal substitution policy is a Nested-subset Base-Stock (NBS) policy. And explain why we chose this policy.

3. Then we will introduce the NBS policy in detail. Specifically, the NBS policy first finds the largest nested-subset of components whose inventory levels are all below the subset's associated base-stock level, and then substitutes only components in the largest nested-subset following the base-stock policy. The optimal replenishment policy of the component with the shortest leadtime is the base-stock policy. But other component's optimal replenishment policies are no longer base-stock policies except when the substitution costs are sufficiently large.
