Comprehensive assessment method for flue-cured tobacco growing district

Abstract

The invention discloses a cured tobacco production area comprehensive evaluation method, comprising: checking the main chemical component indexes of a tobacco sample of each cured tobacco production area; according to the analysis target, selecting and removing specific values; processing cured tobacco production area similarity estimation; processing cured tobacco production area classified evaluation; according to the similarity comprehensive evaluation result, classifying the comprehensive evaluation results, to find each cured tobacco production area comprehensive evaluation. The invention overcomes the defects of the prior art such as the contradiction of the prior art between the linear evaluation and the nonlinear evaluation, the rationality of score divided areas and the mutual contradiction among single index marks, while the evaluation indexes are based on experience judgment and are mostly based on human factor with lacked objectivity, and the like. The invention provides acured tobacco production area evaluation method which combines subjective judgment and objective analysis, can remove noise data, is accurate and stable, with wide application in the cured tobacco production technical field.

Description

technical field [0001] The invention relates to a method for dividing flue-cured tobacco, in particular to a comprehensive evaluation method for flue-cured tobacco production areas. Background technique [0002] The evaluation of flue-cured tobacco production areas is a method to classify the production areas with the same flue-cured tobacco characteristics and distinguish them from the production areas with different flue-cured tobacco characteristics through the analysis of flue-cured tobacco. It is the basis for many cutting-edge research directions of tobacco, such as research on style and characteristic tobacco leaves, research on tobacco leaf processing characteristics, research on modular formula methods and research on leaf group substitution technology. The current evaluation method for flue-cured tobacco production areas is generally as follows: the first step is to divide the score area for each single index, and then score; Or below this range, the score will be...

AI Technical Summary

Problems solved by technology

Now there are many deficiencies in this evaluation method. First, because the evaluation of flue-cured tobacco production areas involves many indicators, and there are high correlations and complex interactions among the individual indicators, it is a nonlinear evaluation problem, but the scoring method is linear. There are basic contradictions between the linear evaluation method and the nonlinear evaluation problem in the evaluation method; second, there are problems such as the rationality of the division of scores and the conflict between the scores of individual indicators, and it is difficult to obtain a reasonable comprehensive evaluation result. The total score evaluation index of the flue-cured tobacco production area is also of low application value in cigarette production

Third, among the many evaluation indicators, which indicators play a key role in the quality of tobacco leaves, and which indicators have less impact on the quality of tobacco leaves, currently only rely on empirical judgments, human factors account for a large proportion, and lack of objectivity
