摘　　要：针对目前惯组批次性能评估方法中存在易受异常样本影响和结果无法检验的问题,提出了两种基于中位数理论的高效率稳健评估方法,称为rp方法与稳健标准差方法。两种方法合理利用了评估过程中的稳健信息,有效地克服了异常样本的影响,并且在此基础上构建了一套完备的批次惯组评估模型,确保统计结果准确可靠。最后,文中给出了具体的工程应用实例和结果分析。Aiming at the problems that how to overcome influence by the abnormal samples and how to check the result in the current evaluation method of the performance of batch of SIMU, two improved and steady methods that based on the median theory are presented （the rp method and the steady standard difference method）. The two improved methods can intelligently use the steady information and overcome influence by the abnormal samples effectively. Additionally, a better model of the performance of batch of SIMU is constructed to guarantee the preciseness and reliableness of result. Finally, An engineering application and the result analysis are proposed as well.
