摘要
为鉴定元件失效率的等级,按目前国家标准GB1772-79规定的抽样方案,需要做大量的试验,构成人力、物力的浪费,做较高等级的鉴定甚至是不可能的.本文采用贝叶斯方法,利用大量的历史数据和工程技术人员的丰富经验确定先验分布,制定出元件失效率等级鉴定试验的一种新方案.按照这一方案,在确保产品质量的前提下,将大大节省试验时间,从而得到十分可观的经济效益。
In order to evaluate the level of the failure rates of the components, a long time and material consuming is required if the sampling plans defined in GB1772-79 (its equivalent in MIL-STD-690)is used. It is almost impossible for these plans to give evaluation for a high level component. The Bayesian method used here, which determines a prior distribution based on large amount of the historical data and plentiful engineering experience, gives a new plan for tests to evaluate level of the failure rate of the components. With the prerequisite of quality assurance of the products, considerable test-time can be saved by using the plan.
