Cigarette working procedure quality overall evaluation system and method based on gray correlation analysis

Abstract

The invention discloses a comprehensive cigarette process quality evaluation system based on grey correlation analysis and a method thereof, aims at overcoming the disadvantage that the existing single process evaluation method can not comprehensively evaluate the overall process quality of the cigarette process, and changing the situation of fuzzy process capability evaluation of a whole line at present. The evaluation system and the method thereof help comprehensively evaluates the quality of a plurality of processes, and can effectively grasp comprehensive situation of the process quality so as to provide basis for the continuous improvement in the process quality, and provide assurance for quality improvement of cigarette products. The system and the method combine the single-process quality evaluation method and the grey correlation analysis method. The method comprises the following steps: firstly, computing process capability indexes of various process parameters; then, comprehensively evaluating a Cpk value by the grey correlation method; finally, obtaining a comprehensive evaluation result which is taken as a process quality rank of various evaluated objects. Production practice can be effectively directed by analyzing the Cpk and the process quality ranking result.

Description

technical field [0001] The invention relates to a system and method for comprehensive evaluation of cigarette process quality based on gray relational analysis, and relates to the field of comprehensive evaluation of tobacco process quality. Background technique [0002] As one of the four elements of cigarette product design, processing technology has a great influence on the quality of cigarette products. At present, the cigarette processing technology is not just a process of purely pursuing physical indicators and reducing consumption, but is sublimated into a process and technical method to improve the inherent quality of cigarette products. Stable and excellent processing technology can retain the inherent good quality of tobacco leaves to the greatest extent, effectively remove the adverse factors of the raw materials themselves, increase the maximum value of cigarette raw materials, and create cigarette products with high product quality, unique aroma style and taste...

AI Technical Summary

Problems solved by technology

The main disadvantage of single-process evaluation is that it is impossible to grasp the overall process quality of the entire line, for example, it is impossible to compare the process quality of the entire line in different months

How to choose a scientific and effective comprehensive evaluation method for process quality, change the current situation of vague evaluation of the process capability of the entire line, so as to improve the process level and improve the quality of cigarette products has become an urgent problem for tobacco companies
