Optimal Deployment of Irreparable, Multi-component Systems

We consider the problem of optimally timing the deployment of individual components in a multi-component system with the objective of maximizing the overall system utility over a finite planning horizon. The condition of each component, and its priority level, evolve stochastically over time while d...

Summary:We consider the problem of optimally timing the deployment of individual components in a multi-component system with the objective of maximizing the overall system utility over a finite planning horizon. The condition of each component, and its priority level, evolve stochastically over time while deployment decisions are subject to availability constraints. We formulate a Markov decision process model for this problem, discuss an application in satellite constellation management and present preliminary results. [PUBLICATION ABSTRACT]
