New Modelling and Solution Frameworks for Multiple Objectives, Decomposability and Impulsivity in Continuous-time Markov Decision Processes
Luke Fairley, Rob Shone, Peter Jacko +1
Impulsive control, in the context of continuous-time Markov decision processes (CTMDPs), refers to actions that instantaneously update the state of the process, leading to theoreti…
Robust Patrol in a Dispersed Environment
Edward Mellor, Kevin Glazebrook, Kyle Lin +1
We consider a patrol problem in which a patroller moves among several geographically dispersed locations to detect attackers that arrive over time. Once the patroller arrives at a…
Dynamic Repair and Maintenance of Heterogeneous Machines Dispersed on a Network: A Rollout Method for Online Reinforcement Learning
Dongnuan Tian, Rob Shone
We consider a problem in which a single repairer is responsible for the maintenance and repair of a collection of machines, positioned at different locations on a network of nodes…
A Bi-Objective Markov Decision Process Design approach to redundancy allocation with dynamic maintenance for a parallel system
Luke Fairley, Rob Shone, Peter Jacko +1
The reliability of a system can be improved by the addition of redundant elements, giving rise to the well-known redundancy allocation problem (RAP). We propose a novel extension t…
