On the Optimality of(s,S)Inventory Policies: A Quasivariational Approach

[摘要] This paper revisits the classical discrete-time stationary inventory model. A new proof, based on the theory ofquasivariational inequality (QVI), of the optimality of(s,S)policyis presented. This proof reveals a number of interesting properties of the optimal cost function. Further, the proof could be used as a tutorial for applications of QVI to inventory control.
