Finite-horizon piecewise deterministic Markov decision processes with unbounded transition rates

摘要

This paper is concerned with the problem of minimizing the expected finite-horizon cost for piecewise deterministic Markov decision processes. The transition rates may be unbounded, and the cost functions are allowed to be unbounded from above and from below. The optimality is over the general history-dependent policies, where the control is continuously acting in time. The infinitesimal approach is employed to establish the associated Hamilton-Jacobi-Bellman equation, via which the existence of optimal policies is proved. An example is provided to verify all the assumptions proposed.
