欧式距离系数在多点生产卷烟产品的均质化评价中的应用
Application of the Euclidian Distance Coefficient in Homogenization Evaluation of Tobacco with Muti-point Production
摘要
Abstract
[Objective ] The technique of the homogenization of same-brand cigarette made in the tobacco from multi-point production base was explored. [ Method] 4 kinds of index values of the cigarette of 2 brands( A, three sort and B, five sort of tobacco) from the regular quality during 2009 -2010 was evaluated in the homogenization with the method of Euclidean similarity coefficient. [ Result] The result of Euclidean similarity coefficient evaluation and the similarity evaluation from consumers were consistent. The similarity coefficient among batches of the same brand in main factory was more than 0.9 and the Euclidean similarity coefficient of the brand of the main factory( Fl) and other 12 branches except F3 was also more than 0.9, which was beyond 0. 87 of acceptance value. The Euclidean similarity coefficient between Fl and F3 was 0.83 with a relevantly high level, however, less than 0. 87 of the acceptable value, resulted from the low value of the following index: the moisture of smoke, the content of nicotine nitrogen, the content of nicotine, the tobacco-loss from the end, the drawing resistance, the degree of total ventilation, the content of dust and moisture in cigarette. There was same the trend in the Euclidean similarity coefficient of A and B among the different production bases; the manufacturer of the highest similarity coefficient was in F5 and F6 and the manufacturer of the lowest similarity coefficient was in F3 and F9. The average manufacturer of the highest similarity coefficient was in F5, F6 and F8 and the lowest, in F3. The 5 indexes; the moisture of smoke, the content of tobacco-loss from the end, the degree of total ventilation, the content dust and moisture in cigarette were main reason causing the difference between two brands based on the analysis of the manufacturer from F3 and F9. [ Conclusion ] The Euclidean similarity coefficient was a better evaluation method of the homogenization of same-brand cigarette made in the tobacco from multi-point production base.关键词
