用Crow模型监测航天在研产品的可靠性

航天产品研制过程中其可靠性是不断增长变化的。为了在研制全过程中监测产品的可靠性变化情况，探讨应用可靠性增长模型和试验数据折算方法相结合的技术，利用产品研制过程中的各种试验信息来动态地评估和预测航天在研产品的可靠性，为产品研制管理提供了依据。简述Crow可靠性增长模型，详细讨论了试验数据折算方法，给出了可靠性增长评估的计算步骤；然后详细介绍某航天在研产品的可靠性分析评估过程和结果。

Monitoring Reliability of Space Cabin-borneEquipment in Development Using Growth Model

The reliability of space cabin borne equipment is constantly growing in its development. In order to monitor and tracking the reliability of the equipment in its whole development process, this paper attempted to apply the technique, which is composed of the Crow model and test data conversion(TDC) method, to dynamically estimate and predict the reliability of the equipment by making full use of various test information in its development. It can provide a foundation for space products development process management. This paper first summarized the Crow model. And the TDC method is discussed. Estimation process of the technique in the reliability analysis and dstimation of a manned space cabin borne electronic equipment in development.
