Title:	Optimality of (s, S) Policies with Nonlinear Processes
Time & Venue:	2018.12.26 13:30 S813
Abstract:	It is observed empirically that mean-reverting processes are more realistic in modeling the inventory level of a company. In a typical mean-reverting process, the inventory level is assumed to be linearly dependent on the deviation of the inventory level from the long-term mean. However, when the deviation is large, it is reasonable to assume that the company might want to increase the intensity of interference to the inventory level significantly rather than in a linear manner. In this talk, inventory replenishment is modelled as a nonlinear continuous feedback process. Both infinite horizon discounted cost and the corresponding optimal (s, S) policy are derived.
