| Abstract: | Based on missed data type-II censored samples,the reliability performances of k/N（G） systems are studied by using Maximum Likelihood Estimation and Bayesian Estimation Methods.The average lifetime of samples,the reliability function and average life are given.At last,the rationality and feasibility of the method are proved by means of the Monte-Carlo simulation. |
