报告摘要：This talk concerns with optimal stopping problems on semi-Markov processes [SMPs] with finite horizon, and aims to establish the existence and computation of optimal stopping times. We first establish the existence of an optimal policy of the semi-Markov decision processes (SMDPs] with additional terminal costs and finite horizon. Based on the optimal stopping problems, we give an explicit construction of SMDPs, which are proven to be equivalent to the optimal stopping times of SMPs. Then,using the results of SMDPs developed here, we not only prove the existence of an optimal stopping time of SMPs, provide an algorithm for computing them, but also find that the optimal stopping times can be characterized by the hitting time of some special sets.Finally, we give an example to illustrate the effectiveness of our conclusions.
