A method and system for evaluating the distribution uniformity of sectional tobacco shreds

The invention discloses a segmented cigarette tobacco distribution uniformity evaluation method and system, comprising the following steps: receiving density measurement data of a plurality of samplecigarettes; the standard deviation of cigarette density and the standard deviation of cigarette density being calculated and the standard deviation data matrix being constructed; the entropy weight TOPSIS method being used to establish the tobacco distribution uniformity comprehensive evaluation model, and the tobacco distribution uniformity score of each sample being calculated. The invention canfully consider the characteristic of uneven distribution of tobacco shreds, comprehensively evaluate the uniformity of tobacco shreds distribution, and provide a basis for better improving the uniformity of tobacco shreds distribution. 本发明公开了种分段式烟支烟丝分布均匀性评价方法和系统，包括以下步骤：接收多个样品烟支的密度测量数据；将烟支光烟分段，并分别计算各分段烟支及整支光烟的密度标准偏差，构建标偏数据矩阵；利用熵权TOPSIS法建立烟丝分布均匀性综合评价模型，计算各样本烟支的烟丝分布均匀性得分。本发明能够充分考虑烟丝分布不均匀的特征，综合评价烟丝分布均匀性，为更好的改进烟丝分布均匀性提供依据。
