Abstract [en]

With respect to future trends in cabin design, this paper takes a close look at two problem areas that produce delays and reduce the time an aircraft is in the air. The first is related to unscheduled maintenance and  the second is related to necessary cabin reconfigurations. Each of the two problem areas are analyzed for time consumption and costs. The research project PAHMIR (Preventive Aircraft Health Monitoring for Integrated Reconfiguration, a cooperation project between Airbus Germany and Hamburg University of Applied Sciences) ads “intelligence” to aircraft components and novel technologies to the aircraft system. These measures will be able to reduce time consumption and costs for unscheduled maintenance caused by the air conditioning system in the order of 8 %. These measures will be able to reduce time consumption for cabin reconfiguration by about 36+%. The upper price limit for economic intelligent quick fasteners seems to be around 500 USD.

Abstract [en]

Unscheduled aircraft maintenance causes a lot problems and costs for aircraft operators. This is due to the fact that aircraft cause significant costs if flights have to be delayed or canceled and because spares are not always available at any place and sometimes have to be shipped across the world. Reducing the number of unscheduled maintenance is thus a great costs factor for aircraft operators. This thesis describes three methods for aircraft health monitoring and prediction; one method for system monitoring, one method for forecasting of time series and one method that combines the two other methods for one complete monitoring and prediction process. Together the three methods allow the forecasting of possible failures. The two base methods use decision trees for decision making in the processes and genetic optimization to improve the performance of the decision trees and to reduce the need for human interaction. Decision trees have the advantage that the generated code can be fast and easily processed, they can be altered by human experts without much work and they are readable by humans. The human readability and modification of the results is especially important to include special knowledge and to remove errors, which the automated code generation produced.
