The amount of information required for reliability assessment of success/failure products is defined and the formula of equivalent information method is deduced.Based on the formula,a method for assessing reliability of initiating explosive devices with small sample size is established.Compared with the assessment method for devices with large sample size,the new method is correct and feasible and can be used to assess the reliability of initiating explosive devices with high reliability requirements. 相似文献
