引信可靠度置信度指标转换及对应抽样检验方案

Fuze Reliability Index and Sampling Inspection Scheme

针对由引信“可靠度置信度”形式的可靠性指标及抽样检验引出的诸多问题,通过对引信“可靠度置信度”形式可靠性指标的数理统计分析,指出了甲乙双方普遍在概念理解上存在的偏差,该指标形式代表的含义与可靠性定义的内涵和相关标准要求的成功率涵义有一定差异。提出对该指标形式按照大样本量对应可接收成功率进行转换,以使引信可靠性指标形式规范、要求合理。在高价值弹药引信抽样检验中建议优先采用(12)方案的一次抽样方案,抽样应首先保证接收成功率指标,使用方的风险可通过连续批累加来保证,与转换指标对应的(12)抽样方案及流程可以兼顾双方的利益。

In view of the fuze“reliability-confidence”in the form of reliability index and sampling inspection of many problems,first of all,fuze“reliability-confidence”in the form of reliability indices were analyzed,and the index of deviation exists in the concept,the connotation of the meaning related standards of success rate and reliability definition were pointed out.It was suggested that the index should be transformed according to the actual quality level(acceptable success rate),so as to make the form of the reliability index of fuze standardized and reasonable.In high value fuze sampling inspection,it was suggested that the primary sampling scheme of(12)scheme should be preferred.The sampling should first ensure the acceptable success rate index,and the risk of the user could be obtained through continuous batch accumulation.
