中文摘要:

      目的 建立一种灰色定权聚类的评估方法, 减少小米品质评价过程中的主观性。方法 基于山西11个地区晋谷21号小米感观品质、营养品质和加工品质方面的基础数据, 构建白化权函数, 建立综合评价指标体系, 确定各小米样品所属的灰类。结果 对11个有代表性的小米品质的灰色定权聚类结果表明: A4、A8、A10属于“高”灰类产品, A1、A3、A5、A6、A9属于“中”灰类, 而A2、A7、A11属于“低”灰类, 即沁县、汾阳、原平3个地区产出的小米品质优良, 阳曲、神池、榆社、浮山、山阴5个地区产出的小米品质中等, 浑源、阳城、芮城3个地区产出的小米综合品质较次。结论 灰色定权聚类结果与实际情况相吻合, 表明构建的小米综合品质灰色定权聚类评估方法可靠。

英文摘要:

      Objective To establish an evaluation method of grey fixed weight cluster to reduce the subjectivity in the process of millet quality evaluation. Methods Based on the basic data on the sensory quality, nutritional quality and processing quality of Jingu 21 millet from 11 regions in Shanxi province, the whitening weight function was constructed, the comprehensive evaluation index system was established, and the gray class of each millet sample was determined. Results The results of grey fixed-weight cluster for the 11 representative millet qualities showed that A4, A8 and A10 belonged to "high" gray products, while A1, A3, A5, A6 and A9 belonged to "medium" gray products, while A2, A7 and A11 belonged to "low" gray products, in other words, the millet produced in Qinxian, Fenyang and Yuanping regions were of good quality. The millet produced in Yangqu, Shenchi, Yushe, Fushan and Shanyin regions were of medium quality, while the millet produced in Hunyuan, Yangcheng and Ruicheng regions were of poor comprehensive quality. Conclusion The results of gray fixed weight cluster evaluation are consistent with the actual situation, which shows that the established gray fixed weight cluster evaluation method for multi-indexes comprehensive assessment of millet is reliable.
