Re-engineering of an Assembly Process: Mapping and Technical Solutions
Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
Due to the changing climate on the market with a higher competitiveness it is important to continuously improve the products and the processes behind the products. In this report the assembly process of fighter aircrafts are studied and compared to new assembly strategies that include mechanical, electrical and hydraulic installations simultaneously as the hull of the aircraft is built. This new way of thinking requires technical solutions to deal with quality problems such as FOD (Foreign Object Debris). Therefore concepts were developed to a conceptual stage to deal with such problems. The wining concept was tested to prove the principal. The second part of the work includes a mapping of factors that are affected when changing the assembly strategy. The mapping process was concluded to get a holistic approach of the situation and to eliminate the possibility of sub-optimization. By having a holistic approach the profit from changing the assembly strategy can be estimated. The assembly strategies that were developed and evaluated for JAS 39 Gripen were; to move parts of the assembly operation of the final assembly (FA) to the structural assembly (SA) the other strategy was to do a complete modularization of JAS 39 Gripen. The strategies were analyzed on an economic level to lay a foundation for further investigation. The information needed to solve the task was gathered through a literature review, interviews and observations. A case study on JAS 39 Gripen was carried out to get a more detailed analysis and to thereafter be set as a framework for the general discussion. The result showed that the problem with FOD can be solved through the conceptual ideas that have been presented. The result of the mapping process showed that there are many factors that might create an extensive profit when changing the assembly strategy.
