Data-driven predictive maintenance scheduling policies for railways

Transportation Research Part C: Emerging Technologies, 2019
Inspection and maintenance activities are essential to preserving safety and cost-effectiveness in railways. However, the stochastic nature of railway defect occurrence is usually ignored in literature; instead, defect stochasticity is considered ...

Aircraft line maintenance scheduling and optimisation

, 2020
With the advent of new technologies and more modern aircraft, many of the maintenance jobs traditionally scheduled for periodic block checks can now be performed in the ‘‘line maintenance” environment, i.e., during layovers between scheduled flights of ...

Scheduled Reference Collection Maintenance:

The Reference Librarian, 1990
In early 1989 a questionnaire was sent to forty-eight public and twelve academic libraries in Rhode Island to ascertain the use of and attitudes toward schedules for reference collection maintenance. The great majority of libraries favored this approach, although the individual schedules varied greatly.
