摘　　要：研究了不同环境条件对导弹产品寿命的影响,利用Poisson过程来描述导弹现场可更换单元(line replaceable unit,LRU)在全寿命周期中的维修情况,给出了一种基于任务剖面的导弹LRU备件规划方法。通过对全寿命周期任务剖面进行分析,综合考虑不同典型任务剖面对LRU可靠性的影响,利用Poisson过程建立LRU备件量模型。通过考虑LRU备件贮存失效和定期检测损耗,对备件量模型进行了修正。结合实例表明,该方法在导弹贮存寿命剖面下对LRU备件量进行了合理规划,确保导弹满足战备完好性要求,并节约了全寿命周期费用。Spare parts programming plays an important role in the missile integrated logistic support. To improve the spare sufficiency, the influence of varied environment conditions on missile life is studied. The Pois- son process is introduced to describe the maintenance status of the missile line replaceable unit （LRU） in whole life cycle, and a spare parts programming method of missile line replaceable LRU is proposed based on mission profile. The influence of varied mission profiles on LRU reliability is analyzed, and the LRU spare model is es tablished by using the Poisson process. Furthermore, due to the LRU spare parts storage failures and term de- tecting loss, the spare model is modified. The proposed method is used for the tactical missile LRU spare parts programming. The result shows that the method is able to program the LRU efficiently, satisfy the missile sys tern availability requirement and economize the whole life cycle charge.
