摘要
文章结合灰色系统理论,把模糊物元分析法中描述待评样本与标准样本的相近程度的欧氏“贴近度”进行改进,利用待评样本在标准样本上的投影值的大小进行综合评价。该方法把待评样本模的大小和待评样本与标准样本变化的一致性结合起来,全面地反应出了各待评样本与标准样本之间的接近程度,并通过实例验证了该方法的全面性和可靠性。
On the basis of grey system theory, this paper improves Euclid approach degree which describes the similar degree between the sample to be evaluated and standard sample in the fuzzy matter-element analysis method, and uses the projection val- ue of the sample to be evaluated on the standard sample to make a comprehensive evaluation. The method combines the module size of the sample to be evaluated and the consistency between the sample to be evaluated and the standard sample in variation to fully reflect the closeness between the sample to be evaluated and the standard sample. Finally the paper employs examples to ver- ify the comprehensiveness and reliability of the proposed method.
