This report summarizes the results of the research project CARISMA. CARISMA was undertaken jointly by ELAN GmbH and Hamburg University of Applied Sciences, through Hamburg Innovation GmbH. The aim was to support ELAN GmbH towards the vision Completion Center, by providing an unbiased outside view and practical scientific approaches of problem solving in aeronautical engineering. The project was divided into 5 Work Packages. WP 1 provided the regulatory requirements towards obtaining DOA as well as the process chain of activities within the future completion center. WP 2 delivered a forecast of cabin modification scenarios that will be undertaken for the next 20 years, as well as an updatable EXCEL tool useful for own calculations. WP 3 investigated the implications of carrying out independent cabin conversions, based on two study cases. WP 4 delivered an overview of the tools required in a completion center. WP 5 analyzed the financial implications of the vision Completion Center. Most of these topics have been approached by ELAN engineers in parallel to the university input. The approaches were however different, while the results were similar. As an overall conclusion, ELAN should invest in the vision Completion Center, first due to the actual highly competitive market context. This should be however done gradually, by starting with small projects and by gaining new capabilities.
