# Optimality of (s, S) Policies in Inventory Models with Markovian Demand

@article{Sethi1997OptimalityO, title={Optimality of (s, S) Policies in Inventory Models with Markovian Demand}, author={Suresh P. Sethi and Feng Cheng}, journal={Oper. Res.}, year={1997}, volume={45}, pages={931-939} }

This paper is concerned with a generalization of classical inventory models (with xed ordering costs) that exhibit (s; S) policies. In our model, the distribution of demands in successive periods is dependent on a Markov chain. The model includes the case of cyclic or seasonal demand. The model is further extended to incorporate some other realistic features such as no ordering periods and storage and service level constraints. Both nite and innnite horizon nonstationary problems are considered…
