Zusammenfassung: A reliable condition monitoring is needed to be able to predict faults. Pattern recognition technologies are often used for finding patterns in complex systems. Condition monitoring can also benefit from pattern recognition. Many pattern recognition technologies however only output the classification of the data sample but do not output any information about classes that are also very similar to the input vector. This paper presents a concept for pattern recognition that outputs similarity values for decision trees. Experiments confirmed that the method works and showed good classification results. Different fuzzy functions were evaluated to show how the method can be adapted to different problems. The concept can be used on top of any normal decision tree algorithms and is independent of the learning algorithm. The goal is to have the probabilities of a sample belonging to each class. Performed experiments showed that the concept is reliable and it also works with decision tree forests (which is shown during this paper) to increase the classification accuracy. Overall the presented concept has the same classification accuracy than a normal decision tree but it offers the user more information about how certain the classification is.

Effects of condition-based maintenance on costs caused by unscheduled maintenance of aircraft
Journal of Quality in Maintenance Engineering, 22(4):394-417

Zusammenfassung: Purpose: The purpose of this paper is to analyze the effects of condition-based maintenance based on unscheduled maintenance delays that were caused by ATA chapter 21 (air conditioning). The goal is to show the introduction of condition monitoring in aircraft systems. --- Design/methodology/approach: The research was done using the Airbus In-Service database to analyze the delay causes, delay length and to check if they are easy to detect via condition monitoring or not. These results were then combined with delay costs. --- Findings: Analysis shows that about 80 percent of the maintenance actions that cause departure delays can be prevented when additional sensors are introduced. With already existing sensors it is possible to avoid about 20 percent of the delay causing maintenance actions. --- Research limitations/implications: The research is limited on the data of the Airbus in-service database and on ATA chapter 21 (air conditioning). --- Practical implications: The research shows that delays can be prevented by using existing sensors in the air conditioning system for condition monitoring. More delays can be prevented by installing new sensors. --- Originality/value: The research focuses on the effect of the air conditioning system of an aircraft on the delay effects and the impact of condition monitoring on delays.

Klassifikation von IT-Sicherheitsvorfällen
DuD - Datenschutz und Datensicherheit, Volume 40(Januar 2016)

ISSN: 1614-0702

Marker: TI-I

Zusammenfassung: Das IT-Sicherheitsgesetz verlangt die Meldung wesentlicher Vorfälle, welche zu Ausfällen oder Beeinträchtigungen von kritischen Infrastrukturen geführt haben oder hätten führen können. Die Definition der dafür zu verwendenden Vorfallsklassifikation steht noch aus. Welche Lehren können aus Erfahrungen mit bestehenden Klassifikationen gezogen werden, die im Rahmen der Arbeit von Computer Emergency Response Teams (CERTs) bereits im Einsatz sind?
