考虑验前信息的成败型产品可靠性评定方法

A Study of Reliability Evaluation Method of Success - Failure Type Production Considering of the Prior Information

结合在航天产品研制过程中，研制阶段的试验信息量大，而鉴定阶段试验信息又有限的实际，给出运用验前信息评定产品飞行可靠性的Bayes评定方法。并通过应用实例，说明了在验前信息的作用下，Bayes法评定航天产品飞行可靠性的客观、公正性。

Combined with the reality that the development testing information content is great while finalization testing information content is limited in the process of developing aerospace products, the study offers Bayes as the evaluation method that uses prior information to evaluate the flight reliability of products. By an application example, this paper presents the objectivity and fairness of Bayes method in evaluation of the flight reliability of aerospace products by the action of prior information.
