Planning for Aircraft Spare Engine and Engine Parts with Simulation: Operations Research and Advanced Analytics

摘要

Inventory planning for expensive asset requires special modeling Simulation is a good tool to solve inventory problems for items with complex replenishment processes. Compared to closed form solutions, it can model the processes more accurately with less restrictions. Savings are significant: 1. As AA upgrades the fleets, the retiring fleets and growing fleets are benefiting from the more accurate planning methodology compared to learning from experience. 2. For 2012, the Shop Pool inventory of CFM56 engine parts (used in 737 aircraft) calculated with our model would have saved 15% in inventory compared to the manually planned inventory.
