Finite approximation for finite-horizon continuous-time Markov decision processes

Abstract

In this paper we study the continuous-time Markov decision processes with a denumerable state space, a Borel action space, and unbounded transition and cost rates. The optimality criterion to be considered is the finite-horizon expected total cost criterion. Under the suitable conditions, we propose a finite approximation for the approximate computations of an optimal policy and the value function, and obtain the corresponding error estimations. Furthermore, our main results are illustrated with a controlled birth and death system.
