为了对自导深弹的自导与引信系统进行可靠性鉴定,文中建立了Bayes可靠性决策模型,运用金字塔方法,提取了该系统可靠性的先验信息,并以抽样净益(ENGS)最大为准则,制定了自导与引信系统的可靠性鉴定试验方案。从实例计算结果来看,按照文中的方法得到的可靠性鉴定试验方案是合理的、可行的,比国家军用标准中所规定的方案分别节省时间36.55%和17.45%。

In order to verify the reliability of homing and fuse system of homing depth charge, the mathematics model of Bayes reliability decision is established in this paper. The prior information of this system reliability is extracted according to MML, and then the plan of reliability verification test about homing and fuse system is worked out in terms of maximum ENGS. In view of the result of example calculation, the plan of reliability verification test obtained according to the method of this paper is reasonable and feasible, and saves the time of 36.55 percent and 17.45 percent respectively compared to the plan of national military standard.
