Maintenance Cost Analysis for Replacement Model with Perfect Minimal Repair
With the evolution of technology, the maintenance of sophisticated systems is of concern for system engineers and system designers. The maintenance cost of the system depends in general on the replacement and repair policies. The system replacement may be in a strictly periodic fashion or on a random basis depending upon the maintenance policy. At failure, the repair of the system may be perfor...
متن کاملReplacement Policies for Cumulative Damage Model with Maintenance Cost
This paper considers replacement polices for an extended cumulative damage model with minimal maintenance at each shock and minimal repair at failure: A system is replaced at time T or at shock number N , and undergoes maintenance or repair between replacements. The expected cost rate is obtained and each optimal T ∗ and N∗ to minimize the cost rate is discussed. It is shown that this model wou...
متن کاملOptimum preventive maintenance policies for systems subject to random working times, replacement, and minimal repair
This paper proposes, from the economical viewpoint of preventive maintenance in reliability theory, several preventive maintenance policies for an operating system that works for jobs at random times and is imperfectly maintained upon failure. As a failure occurs, the system suffers one of two types of failure based on a specific random mechanism: type-I (repairable) failure is rectified by a m...
متن کاملA Multivariate Cumulative Damage Shock Model with Block Preventive Maintenance
This paper is concerned with the dependence structure of a multi-component, cumulative damage shock model, in which a system of components is subject to correlated shock damages and group repairs. A component fails when its cumulative damage exceeds a given threshold, and is then replaced by a new component. We incorporate a block maintenance schedule that simultaneously performs imperfect repa...
متن کاملMaintenance Overtime Policy with Cumulative Damage
We propose an extended maintenance overtime policy for the cumulative damage model where an operating unit suffers some damage due to shocks. It is assumed that the total damage is additive, and the unit fails when the total damage has exceeded a prespecified damage level. It is supposed that we start to observe occurrence of shocks after time T, and the unit is replaced at Nth (N = 1, 2, ...) ...
