This paper presents an analytical model for cost estimation in a single-item, multi-hub (S-1,S) inventory policy-pooling model for high-value spare parts in the aviation industry. The model extends existing, static pooling models by implementing a dynamic failure rate, using a maintenance free operating period (MFOP) as a measurement technique to increase availability of aircraft components. The gained results through a dynamic failure rate show significant effects for a reduction of total costs of ownership and achieving a better operational stock planning, which is demonstrated in a numerical application.
► Integrating a dynamic failure rate in pooling models in the aircraft industry. ► An examination of the impact of a dynamic failure rate, measured by MFOP. ► Downward adjustment of the failure rate. ► Failure reduction will minimize total costs. ► Illustrated by a case study.
