Optimal Maintenance For Stochastically Degrading Satellite Constellations, Timothy J. Cook
Optimal Maintenance For Stochastically Degrading Satellite Constellations, Timothy J. Cook
Theses and Dissertations
This thesis develops a methodology to determine an optimal policy for maintaining a satellite constellation that degrades over time. Previous work has developed a methodology to compute an optimal replacement policy for a satellite constellation in which satellites were viewed as binary entities, either operational or failed. This research extends the previous models by developing an optimal maintenance policy for satellite constellations in which each satellite may operate in a finite number of degraded states. The constellation is assumed to consist of a finite number of satellites, each with a finite number of functions with distinct failure mechanisms. Assuming each …
