讲坛主题:

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.
