摘要: 提出了一种利用同类或相似产品研制试验故障数据并依据AMSAA模型的时间环境因子最优化确定方法,将遗传算法用于时间环境因子的寻优过程,给出了确定最佳时间环境因子的方法、步骤,最后给出了一个工程应用实例.研究结果表明,依此得到的可靠性评估结果与实际使用水平更为接近.为利用产品研制期间故障数据进行可靠性综合评估提供了一条合理的解决途径.

Abstract: One optimization method of acquiring the time environmental factor was proposed which made full use of the failure data from the same kind of products or the similar products in their development tests based upon the AMSAA model, One genetic algorithm method was used to the optimization process of acquiring the time environmental factor, the steps of the process were listed, and at last one practical application example was given. The research result indicated that the reliability evaluation result according to this method was nearer to the reliability level of the product in its practical use. And this method offers one reasonable way for integrated reliability evaluation using the failure data in product's development stage.
