Consideration of changing impact factors for optimization of post-series supply

Abstract

The increased use of electric and electronic components is a trend in several branches of industry. The short life cycles of these innovative components compared with the life cycles of the primary products lead to challenges regarding an effective spare parts management. To guarantee an availability of spare parts during the whole period of the post-series supply, a period of up to 15 years in the automobile industry, a structured planning process is needed. The current approaches for the planning of the post-series supply concentrate on static impact factors to evaluate a supply scenario for the post-series supply, but for a detailed assessment of possible supply strategies changing impact factors have to be considered. A methodical approach for this will be described in this paper. © 2012 IFIP International Federation for Information Processing.
