Aircraft spare parts, a special materials reserve, are hard to forecast demand-time and demand-quantity by normal forecasting theory. - 该模型通过对航空器材使用信息进行可靠性分析，得出零件可靠性寿命函数，并根据给定可靠度下的零件寿命预测航空器材需求时间。
Through parts reliability data the model gets the reliable life function of spare parts and determines parts demand time, depending on part life at given reliabilities. - 方法：应用导航技术和非导航技术重新定位检查器的准确度、需求时间和投射次数被记录在20个实验设备和3个模型装备上。
Methods: Precision, time requirements, and number of scout images for repositioning the fluoroscope, with and without navigation aid, were recorded on 20 test-rig and 3 phantom setups.
