A Faster-Than Relation for Semi-Markov Decision Processes [PDF]
Electronic Proceedings in Theoretical Computer Science, 2020 When modeling concurrent or cyber-physical systems, non-functional requirements such as time are important to consider. In order to improve the timing aspects of a model, it is necessary to have some notion of what it means for a process to be faster ...

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.

Energies, 2022 Oil tanker disasters have been a cause of major environmental disasters, with multi-generational impacts. One of the greatest hazards is damage to the propulsion system that causes the ship to turn sideways to a wave and lose stability, which in storm ...

A Hemimetric Extension of Simulation for Semi-Markov Decision Processes [PDF]
, 2018 Semi-Markov decision processes (SMDPs) are continuous-time Markov decision processes where the residence-time on states is governed by generic distributions on the positive real line. In this paper we consider the problem of comparing two SMDPs with respect to their time-dependent behaviour.

Application of the Pareto front for risk control in the transport system [PDF]
MATEC Web of Conferences, 2019 The article describes the developed model of controlling the process of means of transport operation, in which the choice of control strategy is carried out using non-deterministic methods.

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 ...

Towards Analysis of Semi-Markov Decision Processes [PDF]
, 2010 We investigate Semi-Markov Decision Processes (SMDPs). Two problems are studied, namely, the time-bounded reachability problem and the long-run average fraction of time problem. The former aims to compute the maximal (or minimum) probability to reach a certain set of states within a given time bound.

A survey on semi-Markov decision processes [PDF]
SCIENTIA SINICA Mathematica, 2015 This paper is a survey on semi-Markov decision processes (SMDPs). We present the background, the signi cance, and the research actuality of the in nite horizon expected discounted reward criterion, the long-run expected average reward criterion, the nite horizon expected reward criterion, the expected rst passage reward criterion, the probability ...

Reactive Reinforcement Learning in Asynchronous Environments
Frontiers in Robotics and AI, 2018 The relationship between a reinforcement learning (RL) agent and an asynchronous environment is often ignored. Frequently used models of the interaction between an agent and its environment, such as Markov Decision Processes (MDP) or Semi-Markov Decision
