On spare parts optimization
In the book “Optimal inventory modeling of systems: multi-echelon techniques” the author Craig Sherbrooke, who has developed several important model in this area, describes a part of the model cosidered in this manuscript as follows (in “aircraft language”): “When a malfunction is diagnosed on an aircraft, the malfuncioning item is removed from the aircraft and brought into base supply. If a sp...
متن کاملEfficient 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 کاملCondition based spare parts supply
We consider a spare parts stock point that serves an installed base of machines. Each machine contains the same critical component, whose degradation behavior is described by a Markov process. We consider condition based spare parts supply, and show that an optimal, condition based inventory policy is 20% more efficient on average than a standard, state-independent base stock policy. We further...
متن کاملApproximate dynamic programming for management of high-value spare parts
Purpose – An aircraft manufacturer faces the problem of allocating inventory to a set of distributed warehouses in response to random, nonstationary demands. There is particular interest in managing high value, low volume spare parts which must be available to respond to low-frequency demands in the form of random failures of major components. The aircraft fleet is young and in expansion. In ad...
متن کاملThe final order problem for repairable spare parts under condemnation
We consider a manufacturer of complex machines that offers service contracts to her customers, committing herself to repair failed spare parts throughout a fixed service period. The suppliers of spare parts often discontinue the production of some parts as technology advances and ask the manufacturer to place a final order. We address the problem of determining final orders for such spare parts...
