摘　　要：在定数截尾缺失数据样本下,研究了不可修n中取m串连续k失效系统(简记为k(m)/n系统)的可靠性评估问题.利用Bayes方法和极大似然估计法得到了部件的平均寿命、系统可靠度及平均寿命等可靠性指标的经验Bayes估计.最后利用随机模拟例子说明了本文方法的正确性和可行性.Based on missed data type-Ⅱ censored samples,the reliability performances of m-consecutive-k-out-of-n：F systems are studied by using Bayes Estimate and Maximum Likelihood Estimate approaches.The average lifetime of samples,the reliability function and average life are gived.In the end,the rationality and feasibility of the method are proved by means of the Monte-Carlo simulation.
