Abstract: | A component has time to failure X with density f(·). Opportunities arise as a Poisson process of rate λ. At an opportunity the component may at choice, be replaced at cost c2. At failure the components can either be minimally repaired at cost c1 or replaced at cost c4. Finally the component may be replaced at any time at an ‘interrupt’ cost of c3. We derive expressions for the long-run expected cost rate, and give examples of numerical optimisation with respect to control limits on age at an opportunity, and at an interrupt replacement. |
