英文摘要：

In this paper, we discuss the statistical inference and acceptance sampling plans of WeibuU distribution by considering the Type-Ⅱ hybrid censoring schemes. We derive the exact con- ditional distribution of the maximum likelihood estimator （MLE） as well as the exact confidence in- tervals for the scale parameter of Weibull distribution. We also propose some other methods to con- struct the confidence intervals. For example,asymptotic method. Some simulation studies are carried out to assess their performances. Finally,the acceptance sampling plans are discussed. We develop a sampling procedure based on the exact conditional distribution of the MLE of the scale parameter satisfying the producer and consumer risks. Some numerical results are tabulated for illustrative put- nose.
