基于TOPSIS和GRA法的不同品种初烤烟感官质量综合评价

摘要

[Objective]To evaluate objectively and comprehensively the sensory quality of tobacco varieties in brand oriented base.[Method] Based on 16 flue-cured tobacco varieties planted in Yuxi cultivar garden in 2017,technique for order preference by similarity to an ideal solution (TOPSIS) and grey relational analysis(GRA) were applied to comprehensively evaluate the sensory quality of different varieties.[Result] Dif-ferent evaluation methods showed that among the 16 varieties,the quality of Yunyan 87 was the best,and the CC27 was the worst.The Kappa value of the actual ranking results based on the formula demand and the TOPSIS method was 0.857,and the Kappa value of the evaluation result with the GRA method was 0.571.[Conclusion]The two comprehensive evaluation methods are basically consistent with the actual results.TOPSIS is closer to the actual results ranking.The research can provide a scientific basis for screening and sensory quality comprehensive evaluation based on the formulation demand.%[目的]综合评价品牌导向型基地烟叶品种感官质量.[方法]以2017年玉溪品种园种植的16个烤烟品种为材料,采用多目标决策(TOPSIS)法和灰色关联度分析(GRA)法,对不同品种烤烟感官质量进行综合评价.[结果] 16个品种中均以云烟87感官质量最好, CC27最差.基于配方需求的实际排序结果与TOPSIS法评价结果的Kappa值为0.857,与GRA法评价结果的Kappa值为0.571.[结论]2种综合评价方法均与实际结果表现基本一致,TOPSIS法与实际结果排序更为接近,该研究为基于配方需求的品种筛选和感官质量综合评价提供科学依据.
