6. A few aspects of aircraft noise
Sammanfattning : A few aspects of aircraft noise were evaluated. These were (i) methods of subjective evaluations, (ii) effects of equalization and (iii) the effects of cognitive aspects.In the first paper, sorting algorithms were used instead of conventional paired comparison method in order to reduce the number of pairs in the evaluation of subjective judgments.

7. The flight perturbation problem : operational aircraft rescheduling
Sammanfattning : When there is a perturbation in a carefully planned flight schedule, e.g. an aircraft breakdown, it is important to minimize the negative consequences of this disturbance. In this thesis, a model and a number of solution strategies for the Flight Perturbation Problem is presented. LÄS MER
8. On Aircraft Development : managing complex systems with long life cycles
Sammanfattning : Time plays an important role for the development of aircraft. The aircraft has a long life cycle and is composed of many systems with life cycles that sometimes differ with an order of magnitude in relation to the overall system. LÄS MER
9. Technology Transfer within Related Offset Business : From an Aircraft Production Perspective
Sammanfattning : The aircraft industry is viewed as a prestigious industry by many countries. Emerging economies regard the establishment of aircraft production capabilities as contributing to their competitiveness and technological development. Therefore, in the defence aircraft industry, politics play a key role in competitiveness. LÄS MER
10. Part-out Based Spares Provisioning and Management : A Study for Aircraft Retirement
Sammanfattning : The operation and maintenance phase of a complex technical system may deal with strategicdecisions for asset retirement and end-of-life management. When a fleet of aircraft reachesthe retirement phase, the operation of remaining fleet should still be kept at a defined level ofavailability. LÄS MER
