基于CRITIC赋权法的细支烟物理指标综合质量评价研究

目的 为建立细支烟物理指标综合质量评价方法，以客观评价细支烟卷制过程中的质量稳定性。方法 以某细支卷烟质量、圆周、长度、吸阻和总通风率为基础，利用CRITIC赋权法计算各物理指标的客观权重，并结合其技术标准，计算出每支细支烟的综合得分以及各班组、机台生产细支烟的综合得分和过程绩效指数，建立细支烟物理指标综合质量评价方法。结果 基于CRITIC赋权法计算，细支烟质量、圆周、长度、吸阻和总通风率权重系数分别为0.152、0.147、0.243、0.182和0.276，合格烟支的综合得分≥60分，不合格烟支的综合得分<60分，班组抽检烟支的综合得分与合格率呈线性正相关（R2=0.9569），客观地反映了细支烟主观扣分偏好和物理质量的整体水平。结论 基于CRITIC赋权法建立的细支烟物理指标综合质量评价方法，能客观评价班组和机台的卷烟卷制综合质量水平，及时发现细支烟卷接包装过程中存在的质量问题。

Comprehensive Quality Assessment for Physical Indexes of Slim Cigarette Based on CRITIC Weighting Approach

An evaluation method of comprehensive quality on slim cigarette physical indexes was established to objectively analyze the quality stability during packaging process. In this study, based on weight, circumference, length, suction resistance and total ventilation rate of a certain kind of slim cigarette, the objective weight coefficient of each physical indexes was calculated with criteria importance though intercrieria correlation (CRITIC) weighting method, and the comprehensive score of each slim cigarette and the comprehensive score and process performance indexes of working teams and machine stations were further calculated combined with its technical standard, then the comprehensive quality evaluation method on physical index of slim cigarette was formed. After the calculation with CRITIC weighting approach method, the weight coefficient rates of weight, circumference, length, suction resistance and total ventilation rate of the slim cigarettes were 0.152, 0.147, 0.243, 0.182 and 0.276, respectively. The comprehensive score of qualified cigarettes was equal or greater than 60, while the score of unqualified cigarettes was below 60. The comprehensive scores of the sampling produced by working team exhibited significantly positive linear correlation with qualified rate (R2=0.956 9). It objectively reflected the overall level of physical quality and subjective preference on slim cigarettes. The established evaluation method of comprehensive quality on physical index of slim cigarette can objectively evaluate the comprehensive quality level for working team and machine station of slim cigarettes producing, which is beneficial to find the quality problems during the slim cigarette packing process.
