Planning process for the spare part management of automotive electronics

Hesselbach, Jürgen / Dombrowski, Uwe / Graf, Rene / Wrehde, Johannes / Mansour, Markus

In cooperation with an automobile manufacturer a comprehensive planning process has been developed that facilitates an efficient selection of applicable supply processes which secure the provision with spare parts after the end-of-production of the primary product. The process is divided into a rough cut planning and a detailed planning. The separation of two planning steps significantly reduces the complexity of the planning situation. The approach has been implemented successfully at an automobile manufacturer establishing a systematic planning process of reasonable complexity. Due to the separation of a rough cut and a detailed planning phase the number of potential scenarios that have to be considered has been reduced from 64 to 12. The rough cut planning enables a sensible containment and structuring of the scope of future actions. The detailed planning offers a high flexibility against the uncertainties during the long planning horizon. For the further improvement of the planning process different starting points are conceivable. With the implementation of the process and the supporting data collection processes that include suppliers data availability will improve. An improved availability of product characteristics constitutes the basis for a clustering of products into groups with similar combinations of characteristics and thus, identical supply scenarios. In the long term it will no longer be necessary to perform the planning process for each individual product but only for product clusters.
