基于零失效数据的指数分布可靠性综合评估

摘要

In the course of reliability test and evaluation of the armament ,sometimes the zero‐failure data arises .When firsthand the zero‐failure data are firsthand applied to inspect and evaluate the product reliability of exponential distribution , perhaps a rash advance result is come into being .Contraposing this proplem ,failure information ,weight and process the test data synthetially are introduced to evaluate the product reliability .Examples illustrate that the evaluation result of product reliability of the exponential distribution is objective ,scientific and accepted by both sides .%武备可靠性试验鉴定中，有时会出现零失效数据的情形，直接应用零失效数据检验、评估指数产品可靠性，可能会造成评估结果“冒进”。针对这个现象，提出引进失效信息，综合加权处理，评定产品的可靠性。并通过实例，验证了引进失效信息综合加权评定零失效数据的指数型产品可靠性，评定结果客观、科学，易于被双方共同接受。
