Regulated demand fulfillment strategies for spare parts

The long-term supply with spare parts is a complex task for manufacturers of high-value capital-investment goods and the solution depends on numerous uncertain criteria. Besides the high amount of spare parts which has to be stored, the supply has to be secured for many years. The market requires a high performance of the supply of spare parts (short delivery times, high flexibility of time and quantity). The manufacturer is anxious to reduce the costs and risks of the supply of spare parts (e. g. storage costs, supply and sales risks). The strategy for the fulfilment of the spare part demand has to be selected from the large quantity of available strategies. The complexity of this selection problem is additionally increased by different specifications of the spare parts, which affect the selection of a strategy. Some of these specifications are the suitability of storage, the quality rating, the percentage of sales of the spare parts and the importance of the spare parts for the customer. In the research project "GET – Geregelte Ersatzteil-Bedarfsdeckungs-Strategien" an approach for the selection and continuous monitoring of strategies for the fulfilment of the spare part demand was developed.
