Diploma Thesis aus dem Jahr 2004 im Fachbereich Wirtschaftsingenieurwesen, Note: Very good, 22 Eintragungen im Literaturverzeichnis, Sprache: Englisch, Abstract: Rolls-Royce is a worldwide operating company and focuses on the ideal model of lean manufacturing. Nevertheless, producing and supplying spare parts is very disruptive and restricts the process of continuous improvement. Complex supply chain issues arise due to parts being requested in a very low volume along with a very low frequency demand. This represents the motivation for this thesis, which is to provide a strategy for so-called 'Alien' and 'Stranger' parts. The basis of this thesis is a definition for 'Aliens' and 'Strangers' and an explanation of different part characteristics. The main part of this thesis is a concept for reducing the number of parts with low volume/frequency in an operating business unit with the focus on lean manufacturing. Another key element of this thesis deals with covering costs of an 'Alien' and 'Stranger' production as well as with an effective batching inventory policy. In conclusion, this thesis covers the risk management process to identify risks on 'Alien' and 'Stranger' supply chains.
