| Abstract The objective of this paper is to establish an optimum recommended spare list of aircraft components. The criteria of selecting a spare item for purchase are based on its ability to improve the aircraft operational availability. Marginal analysis is used to sort the spares such that optimum budget utilization is achieved. A mathematical model for aircraft operational availability is derived through the analysis of a typical aircraft operation and maintenance concept. A complex queuing network of aircraft operation and maintenance is simplified to help in deriving the mathematical model for aircraft operational availability. This approach is developed to support the decision making process during the provisioning of aircraft spares. A typical example and its result analysis are given. Also, a complete user-friendly package is developed and implemented using Visual Basic 6. | ||||
