为评价品牌许可生产产品质量的一致性水平,利用双因子方差分析和多重比较分析,将卷烟质量月度稳定性和厂间一致性作为相对独立的两个因素进行分析,进而作出综合性评价。结果表明:①X牌号的质量一致性差异主要来源于厂间的横向波动,同时常规化学指标、主流烟气指标、感官质量指标的厂间差异呈梯次降低的特点;②烟气水分与自然环境的温湿度相关,且烟气水分与余味存在负相关关系;③季节交替时节的烟气水分是影响月度质量稳定性的关键因素之一。因此,品牌许可生产各方的地理、气候差异而引起的烟气水分的差异也是需要重点关注的问题。
In order to evaluate the level of consistency of brand quality of licensed products, two-factor analysis of variance and multiple comparative analysis were used to analyze monthly stability of cigarettes and consistency of plants as two independent factors to make a comprehensive evaluation. The results showed that: ① The quality consistency of X brand mainly originated from the horizontal fluctuation of the plant, meanwhile, the differences between the conventional chemical indicators, the mainstream smoke indicators and the sensory quality indicators showed a step-by-step decrease; ② The relationship between flue gas moisture and natural environment Temperature and humidity, and there is a negative correlation between flue gas and aftertaste. (3) The flue gas moisture in seasonal season is one of the key factors affecting monthly quality stability. Therefore, the differences between the flue gas and water caused by the geographical differences and climatic differences between the producers of the brand and the parties involved in the production are also issues of major concern.
