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.
