Dynamic vs static pricing in a make-to-stock queue with partially controlled production

We consider a capacitated make-to-stock production system that offers a product to a market of price-sensitive users. The production process is partially controlled. On the one hand, the decision-maker controls the production of a single facility. On the other hand, an uncontrolled flow of items arrives at the stock. Such a situation occurs in several contexts; for example, when there is a return flow of products or a fixed delivery contract. We model the system as a make-to-stock queue with lost sales. We address the static pricing problem and the dynamic pricing problem with the objective of maximizing the average profit over an infinite horizon. For both problems, we characterize the optimal production and pricing policy. We also obtain analytical results for the static pricing problem. From numerical results, we show that dynamic pricing might be much more beneficial when the production is not totally controlled.
