| Abstract: | A unit (multiplexor, switch, terminal, processor, etc.) at a remote site is inspected occasionally from a central site to see if it is functioning properly. Two stochastic models are proposed for monitoring remote units whose operational status can be described by an alternating 0–1 process. Optimal inspection schedules are derived based on the objective of maximizing the overall steady state system availability while limiting inspections per-unit-time costs and customer inconvenience. |
