Abstract:
Embodiments herein maintain an unscheduled maintenance rate of a first apparatus, of a group of apparatuses, based on a history of unscheduled maintenance service calls performed on the first apparatus. Other apparatuses in the group of apparatuses have different unscheduled maintenance rates when compared to the unscheduled maintenance rate of the first apparatus. The method/system herein replaces fully used components of the first apparatus that exceed a predetermined full service life, based on usage meters of the components and replaces partially used components of the first apparatus that do not exceed the full service life, based on the usage meters. When directing replacement of partially used components, the method determines the remaining amount of the full service life for each of the partially used components, estimates the occurrence of the next service call for the first apparatus based on the unscheduled maintenance rate for the first apparatus, compares the remaining amount of the full service life for each of the partially used components to the occurrence of the next service call to identify ones of the partially used components that will exceed the full service life before the next service call, and then replaces only the ones of the partially used components that will exceed the full service life before the next service call.
