摘要
针对导弹测试时间不确定、故障发生时间模糊的问题，采用三角模糊数表示单次故障发生时间，通过fuzzy积分得出单位贮存年限的故障发生次数，依据贮存故障率计算方法，建立了导弹贮存可靠性模型。经对比发现，采用三角模糊数形式得出的故障率更能反映导弹故障的发生概率。
Aiming at the problem that the missile testing time was uncertain and the fault time was fuzzy, the single fault time was expressed in triangular fuzzy number. The fault number within unit storage time was confirmed through fuzzy integral. According to the methods of calculating fault rate, the storage reliability model of missiles was built up. It can be seen from comparison that the fault rate confirmed by using triangular fuzzy number could reflect the probability of missile fault more accurately.
