Efficient aircraft spare parts inventory management under demand uncertainty
In airline industries, the aircraft maintenance cost takes up about 13% of the total operating cost. It can be reduced by a good planning. Spare parts inventories exist to serve the maintenance planning. Compared with commonly used reorder point system (ROP) and forecasting methods which only consider historical data, this paper presents two non-linear programming models which predict impending...
متن کاملSpare Parts Inventory Management with Demand Lead–Times and Rationing
We study an inventory system that consists of two demand classes. The orders in the first class need to be satisfied immediately, whereas the orders in the second class are to be filled in a given demand lead–time. The two classes are also of different criticality. For this system, we propose a policy that rations the non–critical orders. Under a one-for-one replenishment policy with backorderi...
متن کاملSpare parts inventory control for an aircraft component repair shop
We study spare parts inventory control for a repair shop for aircraft components. Defect components that are removed from the aircraft are sent to such a shop for repair. Only after the component has been inspected does it become clear which specific spare parts are needed to repair it, and in what quantity they are needed. Market requirements for shop performance are reflected in fill rate req...
متن کاملSpare Parts Inventory Systems under an Increasing Failure Rate Demand Interval Distribution
Managing spare parts inventories is a challenging task and can benefit considerably from any information on the failure rate of the parts. It has often been considered in the stock control literature that parts' failures are only random, caused by external events which results in the assumption of constant failure rate and therefore the consideration of the Poisson process to represent spare pa...
متن کاملSpare parts inventory and demand management . Comparing theoretical approaches with managerial practice
Demand and inventory management for spare parts are different than for components used in assembly of finished products, in reason of lumpy demand, larger variety and risk of stock obsolescence. The paper deals with three aspects: 1) a description of the elements of complexity peculiar to the spare parts supply chain; 2) a framework and a literature review about spare parts demand and inventory...
