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.

Application of Generator-Electric Motor System for Emergency Propulsion of a Vessel in the Event of Loss of the Full Serviceability of the Diesel Main Engine

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 ...

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 Management
This 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 ...

A Fast-Pivoting Algorithm for Whittle’s Restless Bandit Index

Mathematics, 2020
The Whittle index for restless bandits (two-action semi-Markov decision processes) provides an intuitively appealing optimal policy for controlling a single generic project that can be active (engaged) or passive (rested) at each decision epoch, and ...

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

Research of reliability and efficiency of technological processes of mechanical assembly production on the basis of the common semi-Markov model

MATEC Web of Conferences, 2018
In the article a common semi-Markov mathematical model is considered that allows one to investigate the productivity and reliability of various technological processes of mechanical assembly production.

Learning to maximize reward rate: a model based on semi-Markov decision processes

Frontiers in Neuroscience, 2014
When animals have to make a number of decisions during a limited time interval, they face a fundamental problem: how much time they should spend on each decision in order to achieve the maximum possible total outcome.
