基于多源信息的发动机无故障数据可靠性评估

摘要

According to the reliability assessment of zero-failure data of missile engine, a method for reliability assessment based on multi-sources information is presented. Both the modified MLE and Bayes estimation were comprehensively used in the method. The algorithms of weighted value for different information sources, and the procedures and a numerical example for assessment are given out. The result shows that calculation in the method is simple and assessing result is reasonable. Thus, the method is proved to be applicable and effective.%针对弹用发动机无故障数据可靠性评估问题,提出基于多源信息的可靠性评估方法；综合应用修正极大似然估计和Bayes估计方法,给出信息源权值的计算公式和可靠性评估步骤,最后给出应用实例.计算结果表明,多源信息融合方法计算简单,评估结果合理,具有一定工程应用价值.
