Flue-cured tobacco quality benefit comprehensive evaluation method and system based on data driving

Abstract

The invention discloses a flue-cured tobacco quality and benefit comprehensive evaluation method and system based on data driving, and the method comprises the steps: collecting influence factors andevaluation index data in flue-cured tobacco cultivation, and removing abnormal data in the data; performing principal component analysis on the flue-cured tobacco quality benefit data, and establishing a flue-cured tobacco quality benefit comprehensive evaluation standard; grey correlation analysis is carried out on the relation between the influence factors related to the flue-cured tobacco cultivation process and the indexes of the flue-cured tobacco quality benefits; on the basis of correlation analysis, establishing an evaluation model of each index by utilizing an artificial neural network according to each index of the flue-cured tobacco quality benefit; after the evaluation of each index is completed, the flue-cured tobacco quality benefit is comprehensively evaluated through a principal component analysis result. The method has the beneficial effects that the evaluation difficulty can be reduced while the flue-cured tobacco quality benefit is comprehensively and comprehensivelyreflected by utilizing the layered evaluation method.

Description

technical field [0001] The invention relates to the field of flue-cured tobacco quality and benefit evaluation, and more specifically, relates to a data-driven comprehensive evaluation method and system for flue-cured tobacco quality and benefit. Background technique [0002] Flue-cured tobacco is an important agricultural product in my country's economic crops, and occupies an important position in agricultural economy, international trade and fiscal revenue. In the cultivation of flue-cured tobacco, the quality benefit of flue-cured tobacco is the result of the joint action of flue-cured tobacco species, ecological environment and cultivation process. The traditional quality and benefit evaluation of flue-cured tobacco is often based on the personal experience of tobacco farmers, which is highly subjective and has no theoretical basis. In order to reduce the subjectivity in the evaluation process, some scholars use methods such as fuzzy evaluation method to evaluate the q...
