Complex network construction method for key factors of a cigarette cut-tobacco making process

Abstract

The invention belonging to the tobacco field discloses a complex network construction method for key factors of a cigarette cut-tobacco making process. A node set of a complex network is formed basedon different attribute data; correlation between nodes is calculated by using a covariance method, a network path is determined, and a preliminary complex network structure is constructed; complex network structure optimization is realized based on maximum and minimum hill climbing algorithms; and according to a maximum likelihood estimation method, complex network parameters are determined. Withthe complex network formed by the method, a relationship between process parameters and process quality indicators during the cut-tobacco making process can be systematically analyzed; the influenceson the cigarette quality by key process parameters and process quality indicators during the cut-tobacco making process can be analyzed globally; and the data support is provided for making and modifying the cut-tobacco making process standard, so that the cigarette quality stability is guaranteed.

Description

technical field [0001] The invention relates to a method for constructing a complex network, in particular to a method for constructing a complex network of key factors in the shredded cigarette process, and belongs to the field of tobacco. Background technique [0002] Silk making is the core part of the cigarette processing process, one of the key links that determine the quality of cigarette processing, and plays a key role in improving the overall quality of cigarette products. However, the silk-making process has many processing steps, a long process flow, and complex processing methods, and its impact on cigarette quality is the systematic comprehensive result of the interaction, mutual influence and mutual regulation of the key factors of the silk-making process and the environmental factors of the silk-making process. At present, there are a lot of technological researches in the process of making shredded tobacco, such as the loosening and regaining moisture in the ...

However, the silk-making process has many processing steps, a long process flow, and complex processing methods, and its impact on cigarette quality is the systematic comprehensive result of the interaction, mutual influence and mutual regulation of the key factors of the silk-making process and the environmental factors of the silk-making process.

At present, there are a lot of technological researches in the process of making shredded tobacco, such as the loosening and regaining moisture in the processing method, the drying process of shredded leaves, the moisture content of shredded tobacco in quality indicators, and the structure of shredded tobacco, etc., all of which have a significant impact on the quality of cigarettes. The research focuses on a key process or an important quality index, lacking a systematic method that can incorporate all influencing factors
