Cigarette manufacturing quality stability evaluation method

Abstract

The invention belongs to the technical field of cigarette production, and particularly relates to a cigarette manufacturing quality stability evaluation method. The method mainly comprises steps of firstly, carrying out hierarchical classification on cigarette quality stability according to manufacturing processes of cigarettes; then, carrying out quantization representing on single-factor variables on a machine bench and carrying out weight assignment; evaluating manufacturing quality stability of a single machine bench, wherein the evaluation result of the machine bench is equal to the weighted average of a single-factor evaluation result; and finally, carrying out stability evaluation on batch manufacturing quality and judging the evaluation result. According to the invention, stability of a single variable in the manufacturing process can be evaluated; quality stability of the machine bench and stability of batch comprehensive quality can be evaluated; cigarette manufacturing level can be improved; and powerful support is provided for improving of product quality stability.

Description

technical field [0001] The invention belongs to the technical field of cigarette production, and in particular relates to a method for evaluating the stability of rolling quality of cigarettes. Background technique [0002] Cigarettes are fast-moving consumer goods, and the stability of their rolling quality has a direct and significant impact on consumers' sensory experience. There are many physical indicators controlled in the rolling and processing process of cigarettes, which are interrelated and restrict each other, and jointly exert an influence on the quality and stability of cigarettes. [0003] At present, the evaluation of the quality of cigarettes is mainly through single-factor variable analysis of physical indicators, and statistical analysis of variance, statistical hypothesis testing and other methods to analyze the significance of differences in the mean value and standard deviation of the indicators, so as to evaluate the quality stability of the rolling pro...

Problems solved by technology

First of all, when there are many evaluation indicators, the single-factor statistical evaluation and analysis workload is heavy, and the later data processing is complicated, which increases the complexity of the synergy evaluation of various indicators, which is not conducive to making a fast, accurate and objective evaluation conclusion on the stability of cigarette quality Secondly, when cigarette manufacturers use a single-factor index control system to improve the quality of cigarettes, it may increase the fluctuation of another (or multiple) quality indexes while improving the stability of one quality index, which is difficult to effectively Intuitively reflect the degree of correlation between each single factor and guide the improvement of the comprehensive processing quality of cigarettes; finally, different cigarette companies currently have great differences in the positioning of cigarette sensory styles, and the degree of emphasis on physical indicators of cigarettes varies. Different indicators have different control weights and control ranges, and it is difficult to reflect the differentiated evaluation results of cigarette rolling quality and style in the current evaluation system that does not include differentiated weight values
