Screening and handling method for evaluating climate indexes of cigarette base and evaluation method for cigarette raw material base

Abstract

The invention discloses a screening and handling method for climate indexes. The screening and handling method comprises the steps that climate monitoring indexes in a cigarette raw material producing area are used as the basis, factors and correlation analysis are applied to determine a characteristic index of a climate evaluation factor, probability distribution and standard deviation method weight coefficients are adopted to obtain the evaluation standard for the characteristic index, K-means clustering and multi-accumulating stepwise discriminant analysis are used for building a discrimination function and inspecting accuracy of the discrimination function, finally, a base unit climate index comprehensive classification result is determined, and the cigarette industrial raw material base layout is optimized according to the result. According to the screening and handling method for the climate indexes, the climate indexes capable of accurately analyzing and evaluating the cigarette raw material base are screened out more systematically and more comprehensively from the climate indexes of a plurality of base units, the lateral linkage of the climate indexes is built, and redundant information among the climate evaluation indexes is avoided. The invention further provides an evaluation method for the cigarette raw material base, and the decision-making basis and theoretical supports can be effectively and rapidly provided for optimization of the cigarette industrial enterprise base unit layout.

Description

technical field [0001] The invention belongs to the technical field of cigarette raw materials, and specifically relates to a screening and processing method for evaluating climate indicators of cigarette bases and an evaluation method of cigarette raw material bases. Background technique [0002] Under the background of accelerated reform and adjustment of the national tobacco industry, under the new development opportunities and new development space, the supply and optimized allocation of cigarette raw materials will be the cornerstone and key link of the long-term development strategy of cigarette brands. High-quality cigarettes with stable quality and quantity Cigarette raw materials are the key to ensuring stable quality of cigarette brands and successful brand expansion. Creating high-quality cigarette brands with high-quality cigarette raw materials can also effectively solve the problem of homogeneity of cigarette brands. With the State Tobacco Monopoly Administrat...

Problems solved by technology

[0004] In recent years, relevant scholars have used membership function and principal component analysis to analyze and evaluate climate suitability, and then determine the layout of base units. However, there are many climate indicators that characterize cigarette raw material bases. The information can fully reflect the climate index information, but there is a strong correlation between each index, resul...
