Polish Maritime Research, 2020 The article presents the three-state semi-Markov model of the process {W(t): t ≥ 0} of state transitions of a ship power plant machine, with the following interpretation of these states: s1 – state of full serviceability, s2 – state of partial ...

Hierarchical dialogue optimization using semi-Markov decision processes [PDF]
Interspeech 2007, 2007 This paper addresses the problem of dialogue optimization on large search spaces. For such a purpose, in this paper we propose to learn dialogue strategies using multiple Semi-Markov Decision Processes and hierarchical reinforcement learning. This approach factorizes state variables and actions in order to learn a hierarchy of policies. Our experiments

Some work and some play: microscopic and macroscopic approaches to labor and leisure. [PDF]
PLoS Computational Biology, 2014 Given the option, humans and other animals elect to distribute their time between work and leisure, rather than choosing all of one and none of the other.

Optimal maintenance of deteriorating equipment using semi-Markov decision processes and linear programming [PDF]
International Journal of Industrial Engineering and ManagementThis paper considers a mathematical model analysing the deterioration of system equipment and available maintenance options. Under specific conditions on costs and transition probabilities of the model, the issue of ideal maintenance of the equipment by ...

Nonstationary Continuous Time Markov Decision Processes in a Semi-Markov Environment with Discounted Criterion [PDF]
, 1995 This paper deals with the nonstationary continuous time Markov decision process in a semi-Markov environment with discounted criterion. The model can describe a system that itself can be modeled by a countable state nonstationary continuous time Markov ...

Non-Stationary Semi-Markov Decision Processes on a Finite Horizon [PDF]
, 2012 We introduce and study a class of non-stationary semi-Markov decision processes on a finite horizon. By constructing an equivalent Markov decision process, we establish the existence of a piecewise open loop relaxed control which is optimal for the ...

Mixed Markov Decision Processes in a Semi-Markov Environment with Discounted Criterion [PDF]
, 1998 This paper presents a new model: the mixed Markov decision process (MDP) in a semi-Markov environment with discounted criterion. It describes a system which behaves like a MDP except that the system is influenced by its semi-Markov process environment ...
