Problems of modern aircraft maintenance

Modern Aircraft Design Techniques

Remarks on Modern Track Geometry Maintenance

A short survey on modern track maintenance methods is given, concentrating on the developments in recent years. The ongoing refinement of the machinery should be shown as the influence of IT-solutions. On top the economic view to the track infrastructure is briefly demonstrated. Further developments in track hardware solutions must respect the obtained high level of track work mechanization. H...

IDS: Improving Aircraft Fleet Maintenance

This paper describes the Integrated Diagnostic System (IDS), an applied AI project concerned with the development of hybrid information systems to diagnose problems and help manage repair processes of commercial aircraft fleets. A study at one major airline indicated that significant benefits could accrue (approximately 2% of overall maintenance budget) through the use of innovative information...

Evolutionary Maintenance for Aircraft Engines

Maintenance and, in particular, maintenance policy plays a major -*art in achieving systems operational effectiveness at minimkm cost. The traditional approach to maintenance planning involves selecting optimal policies from known maintenance strategies such as scheduled inspection, preventive maintenance, corrective maintenance, oncondition maintenance etc. Using a traditional approach one may...

Aircraft landing problems with aircraft classes

This paper focuses on the aircraft landing problem that is to assign landing times to aircraft approaching the airport under consideration. Each aircraft’s landing time must be in a time interval encompassing a target landing time. If the actual landing time deviates from the target landing time additional costs occur which depend on the amount of earliness and lateness, respectively. The objec...
