This paper has presented a novel approach for the calculation of life cycle costs and ecological impacts for complex technological products. The approach consists of a hybrid top-down and bottom-up interdisciplinary examination of civil aircraft. The methodology has been exemplified by a civil aircraft fuselage, where a combined economic and ecological evaluation of the production process has been made to show general practicability of the method. The other life cycle phases have been discussed The result shows that choosing composite materials for a fuselage is preferable in economic and ecological terms, based on the assumptions. However, different databases could potentially lead to other results, so detailed data quality assessments and uncertainty analysis still need to be performed. The approach described can be transferred to other components of an aircraft. It enables to detail and model aircraft design and manufacturing decisions on a detailed technical level, but also shows the effects within the overall life cycle. After validating the production analysis methodology, a calculation tool has been developed. The next step will be to integrate this calculation tool within the ATLA Life Cycle Analysis Framework. This integration will help to enable fast and easy calculations and optimizations of technical design decisions along the entire life cycle of an aircraft. Other steps will consider further detailed evaluations on an in-depth component level (such as the fuselage, empennage, wings, et cetera). Data quality, sensitivity and uncertainty analysis have not been performed yet. The integration of the production tool into the framework will enable automated, extensive parameter studies along the entire life cycle. Afterwards, sensitivity analysis as well as subsequent uncertainty analysis will be performed along the life cycle chain. It is planned to identify the parameters with the highest influence on the model and on the economical as well as ecological result.
