The intent of this book is to present recent results in the control theory for the long run average continuous control problem of piecewise deterministic Markov processes (PDMPs). The book focuses mainly on the long run average cost criteria and extends to the PDMPs some well-known techniques related to discrete-time and continuous-time Markov decision processes, including the so-called average inequality approach'', vanishing discount technique'' and policy iteration algorithm''. We believe that what is unique about our approach is that, by using the special features of the PDMPs, we trace a...
