This paper studies the expected average cost control problem for discrete-time Markov decision processes with denumerably infinite state spaces. A sequence of finite state space truncations is defined such that the average costs and average optimal policies in the sequence converge to the optimal average cost and an optimal policy in the original process. The theory is illustrated with several examples from the control of discrete-time queueing systems. Numerical results are discussed.

Holding Cost

A Markov decision chain with countable state space incurs two types of costs: an operating cost and a holding cost. The objective is to minimize the expected discounted operating cost, subject to a constraint on the expected discounted holding cost. The existence of an optimal randomized simple policy is proved. This is a policy that randomizes between two stationary policies, that differ in at most one state. Several examples from the control of discrete time queueing systems are discussed.
