Consideration of Changing Impact Factors for Optimization of Post-series Supply

Abstract

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.

Determination of the Spare Parts Demand for Maintenance, Repair and Overhaul Service Providers

“…These supply strategies are the development of a compatible successive product generation, the storing of a final lot, the periodical internal or external production, the reuse of used components and the repair of used components. [8], [9], [10] The aviation industry is characterized by extremely long life-cycles of the primary products with a high degree of efficiency, small lot sizes, a strict regulation and a high degree of individualization. The share of the services business in the aviation industry is very high.…”
