基于 D-S 证据理论的航天设备寿命预测方法
Lifetime prediction of aerospace equipment based on D-S evidence theory
摘要
Abstract
An information fusion method was proposed based on D-S evidence theory and Bayes theory for lifetime prediction of important aerospace equipment, momentum wheel. Fi rstly,multi-source life information were collected and mined to obtain the prior distribution of the momentum wheel′s lifetime,in order to bui ld D-S evidence collections.Secondly,D-S combination rule was used to obtain reasonable weight allocation for prior distributions.After that,fusion posterior distribution was figured out and the values of life parameters were also estimated. Finally, according to parameters′ estimation, the lifetime prediction for momentum wheel was derived. Simulation result shows that the prediction using the proposed method is closer to the real lifetime measurements.关键词
