in this paper, the scheduling problem with nonresumable jobs and maintenance process is considered in order to minimize the makespan under two alternative strategies. the first strategy is to implement the maintenance process on the machine after a predetermined time period and the second one is to consider the maximum number of jobs that can be done with a special tool. we have proposed a new ...

The use of the building is to support activities or as infrastructure for owners users in optimally carrying out their daily activities. expected be flexible following flow changes that occur later. This what underlies need maintenance In LPMP Dormitory building, have not been managed properly. order better, a management plan made on architectural and utility components building. Starting from ...

This paper considers a single-machine scheduling with a position-dependent aging effect described by a power function under maintenance activities and variable maintenance duration considerations simultaneously. We examine two models of the maintenance duration in this study. The objective is to find jointly the optimal maintenance frequency, the optimal maintenance positions, and the optimal j...

This paper presents how the Inspection Development Framework’s (IDF) novel maintenance scheduling technique increased aircraft utilization and availability in a sample of United States Air Force’s (USAF) C-5M Super Galaxy fleet. The hypothesis tested was “Can we execute segmented requirements during ground time opportunities order to optimize flying?” We applied IDF decompose C-5M’s five-day Ho...

This paper focuses on single machine scheduling subject to machine deterioration. The current maintenance state of the machine is determined by a maintenance level. While jobs are processed this maintenance level drops by a certain, possibly job-dependent, amount. A maintenance level of less than zero is associated with the machine’s breakdown and is therefore forbidden. Consequently, schedule ...
