摘要
Inventory control implies dynamic decision making. Therefore, dynamic programming seems an appropriate approach to look for order policies. For finite horizon planning, the implementation of service level constraints provides a big challenge. This paper illustrates with small instances the implementation of stochastic dynamic programming (SDP) to derive order policies in a straightforward way for systems with non-stationary demand and service level constraints. The small instances allow to perform a full enumeration of possible policies and show that the SDP derived policies are not necessarily optimal.
