Maintenance policy under multiple unrevealed failures

Qüestiió: quaderns d'estadística i investigació operativa, 2002
The unrevealed failures of a system are detected only by inspection. In this work, an inspection policy along with a maintenance procedure for multiunit systems with dependent times to failure is presented. The existence of an optimum policy is also discussed.
