Abstract:Aviation spare parts provisioning is a highly complex problem. Traditionally, provisioning has been carried out using a conventional Poisson-based approach where inventory quantities are calculated separately for each part number and demands from different operations bases are consolidated into one single location. In an environment with multiple operations bases, however, such simplifications can lead to situations in which spares -although available at another airport -first have to be shipped to the locatio… Show more

The inventory system of repairable items is a managerial tool used to integrate all information concerning on-hand inventories and movements for new and repaired items. The paper describes developing a simulation model for managing the inventory of repairable items for a manufacturing system where faulty items are sent to a repair shop with uncertain failure rates, lead times, and repair times. The proposed model imitates processing and controlling the on-hand inventory of repaired items and replenishing the inventory of new items using the minimum/maximum ordering policy in a flexible and risk-free environment. We exhibit the appropriateness and effectiveness of the suggested simulation model using a demonstrative case problem. The developed model can be relied on as a tool for estimating healthy on-hand inventories of new and repaired items, downtime, and back-ordered items due to the unavailability of repaired items.

“…In Yang and Du (2004) an evaluation method to facilitate the initial provisioning of the critical spare parts that have significant impacts on the operational availability and total life-cycle cost is proposed. Lendermann, Thirunavukkarasu, Low and McGinnis (2012) applied simulation-based optimization to a multi-location inventory problem and demonstrated how total service lifecycle cost can be reduced without increasing risk promptly from the Initial Provisioning stage by putting into practice proper logistics policies.…”
Section: Spare Parts Management Decision Instancesmentioning
Abstract:Purpose: This manuscript explores the link between Spare Parts Management and Total Costs of
Ownership or Life Cycle Costs (LCC).Design/methodology/approach: First, this work enumerates the different managerial decisions instances in spare parts management that are present during the life cycle of a physical asset. Second, we analyse how those decision instances could affect the TCO of a physical asset (from the economic point of view). Finally, we propose a conceptual framework for incorporating the spare parts management into a TCO model.
Findings:The recent literature lacks discussions on the integration of spare parts management with the Total Costs of Ownership (TCO). Based in an extensive literature revision we can declare that the computation of costs related to spare parts management has been neglected by TCO models.
Originality/value:The contribution of this paper is twofold. First, a literature review and identification of a series of spare parts management decision instances and its relationship with TCOs is presented in this paper. Second, a conceptual framework is suggested for linking those -991-Journal of Industrial Engineering and Management -http://dx.doi.org/10.3926/jiem.2083 decisions instances to a total cost of ownership perspective. Some research questions and future research challenges are presented at the end of this work.
“…Lee et al (2008) develop a solution framework that integrates a multi-objective evolutionary algorithm (MOEA) with the multi-objective computing budget allocation (MOCBA) method for the multi-objective simulation optimization problem applied to the aircraft spare parts allocation problem. Lendermann et al (2012) investigate the multilocation inventory problem by quantifying synergy potential between locations. They also discuss how the total service lifecycle cost can be further reduced without increasing risk right away from the initial provisioning (IP) stage onwards by taking into account advanced logistics policies such as pro-active re-balancing of spares between stocking locations.…”
