Abstract:

Requirements of opportunistic replace ent inspecti n policies are examine the expected number per unit time OF OPPORTUNISTIC joint REPLACEMENTS OF THE UNIN PECTED PART AN NE OF THE MONIT RE PARTS THE EXPECTED NUMBER PER UNIT TIME OF PLANNE REPLACEMENTS OF THE UNINSPECTED PART THE PROBABILITY OF A CERTAIN NUMBER OF FAILURES OF A MONITORED PART IN A SPECIFIED INTERVAL OF TIME THE EXPECTED NUMBER PER UNIT TIME OF OPPORTUNISTIC INSPECTIONS -- INSPECTIONS OF THE NON-MONITORED PART WHICH ARE TRIGGERED BY FAILURES OF THE MONITORED PART AN THE EXPECTED NUMBER per unit time of planned inspections of the non-m nitored part. As an example the opportunistic replacement policy is applied to the rocket engines of a hypothetical ballistic missile. This illustrative anal si indicate that b th the expected number per nit time of opportunistic joint replacements of the rocket engines and re-entry vehicle and the expected n mber per unit time of replacements of the rocket engines due to mandatory replacement are hig ly sensitive to changes in the rocket engine failure rate. The expected number per unit time of opportunistic joint replace ents of the rocket engines an the guidance and control system is relatively unaffected by change in the engine failure rate.
