基于距离—矩法判据的多源寿命信息融合

Multisource Distance-Moment Lift Information Fusion Based on Criterion

针对小子样复杂系统的可靠性信息融合技术展开研究，解决同总体多源信息的科学利用与融合问题。该方法从数据层融合人手，考虑了各源验前信息的可信度，根据矩法估计原理求解各种可能验前分布的参数。采取距离作为度量选取最佳融合验前分布丽数。最后通过MATLAB仿真实例对4种常见分布进行了研究，验证了该方法的有效性。

In this paper, the technology of the reliability information fusion from the small sample complex systems was studied, and the scientific use and fusion of the multisource information from the same population was solved. The method starts from the data fusion, considers the reliability of prior information from various sources, and solves all possible parameters of the prior distribution according the moment estimate principle. It selects the best fusion function from the prior distribution by the measurement of distance. Finally, the MATLAB simulation examples of the 4 common distributions were studied to verify the validity of the method.
