基于雷达图的烤烟外观质量综合评价

Comprehensive Evaluation of Appearance Quality of Flue-cured Tobacco Based on Radar Graph

根据雷达图的特性,提出了基于雷达图的烤烟外观质量综合评价方法。先对烤烟外观质量评价指标数据进行标准化处理及非线性变换,再提取雷达图的面积和边长平方和作为综合评价指标的特征量,然后按评价函数计算各烤烟外观综合质量评价值,同时给出综合评价结果。并应用建立的方法进行了实例分析计算,结果表明,应用该方法对烤烟外观质量综合评价结果与外观质量定性评价结果一致。因此,雷达图法能够对烤烟外观综合质量进行准确评价,雷达图可以作为烤烟外观质量综合评价分析中的辅助工具。

A comprehensive evaluation method based on radar graph for the appearance quality of flue-cured tobacco was proposed, the main steps are as follows： the data indicating the appearance quality of flue-cured tobacco were standardized and non-linearly transformed, the area and square sum of side length of radar graph were taken as the characteristic values of evaluation, then calculated each appearance quality evaluation value of flue-cured tobacco with evaluation function, and obtained the results of comprehensive evaluation. The results of a living example calculated and analyzed by the established method showed that it agreed with the results of qualitatively evaluation. It implied that the radar graph method can accurately evaluate the comprehensive appearance quality of flue-cured tobacco and can be used as an assistant tool for the comprehensive evaluation of flue-cured tobacco appearance quality.
