Conditions for the Solvability of the Linear Programming Formulation for Constrained Discounted Markov Decision Processes
The following result has been obtained by F. Dufour (Inria CQFD) and T. Prieto-Rumeau.
We consider a discrete-time constrained discounted Markov decision process (MDP) with Borel state and action spaces, compact action sets, and lower semi-continuous cost functions. We introduce a set of hypotheses related to a positive weight function which allow us to consider cost functions that might not be bounded below by a constant, and which imply the solvability of the linear programming formulation of the constrained MDP. In particular, we establish the existence of a constrained optimal stationary policy. Our results are illustrated with an application to a fishery management problem.
