| Abstract: | Information fusion of multiple sources under different population and small sample conditions is a key problem. The reliability testing information fusion methods are summarized under small sample conditions. On some hypotheses, the reliability information fusion methods using the data from the non-identical environment are studied. The simulation shows that by the fusion methods we can take full advantage of the information and give a more reasonable conclusion. |
