Problems solved by technology

If the calculated nicotine value and the total amount of blending do not meet the target, it needs to be modified according to experience, which needs to be repeated many times, and multiple index items cannot be taken into account. Meet the requirements, but it is difficult to meet the needs of the enterprise

Embodiment Construction

[0052] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0053] The first-cured tobacco blending scheme proposed in this embodiment uses genetic algorithms to assist in optimization design. According to the different needs of different brands for different tobacco leaf quality, a plurality of first-cured tobacco sets suitable for blending can be selected, and the blending can be set by Multiple target constraints such as total sugar, total nicotine, reducing sugar, total nitrogen, protein, chlorine, potassium, Schmuck value, ratio of sugar to nicotine, ratio of potassium to chlorine, and expected yield of baked slices, using optimized combination technology, Recommend a list of optimized schemes and the proportion of each flue-cured tobacco, and calculate and analyze the estimated output, physical and chemical indicators of the scheme.

[0054] The so-called genetic algorithm is a global search...

Abstract

The invention discloses an initially baked tobacco formula threshing optimized design method based on a genetic algorithm. The initially baked tobacco formula threshing optimized design method comprises the following steps of: selecting n initially baked tobaccos from a tobacco database, and reading the inventory of the n initially baked tobaccos and index values of m chemical index items; setting a target value of a cigarette formed by the current formula threshing; taking the n initially baked tobaccos as n genes, forming a chromosome by randomly entitling different inventory using proportions to each gene, and constructing an initial group by a plurality of different chromosomes by the same method; calculating j chromosomes with high adaptability by using the initial group according to the genetic algorithm, and judging whether the j chromosomes with high adaptability meet a set target value; and outputting the chromosomes which meet the target value and serve as an initially baked tobacco formula. The genetic algorithm is applied to a formula threshing scheme for the initially baked tobaccos, so that the formula threshing scheme which closely meets the demand of a user can be obtained, and the design cost and the design time are saved.

Description

Technical field [0001] The invention belongs to the technical field of tobacco formulas, and specifically relates to a formula threshing optimization design method for forming a sheet of tobacco by using freshly-cured tobacco leaves. Background technique [0002] Tobacco leaves are the foundation of tobacco companies. To stabilize and improve the quality of cigarette products and expand the market share of products, the tobacco leaves used in cigarettes are essential. After the tobacco leaves are picked, they first need to be roasted to form a flue-cured tobacco, and then the flue-cured tobacco formula is threshed to form a piece of tobacco or a formula module before it can be provided to the cigarette enterprise for formula use. [0003] The so-called recipe threshing (or blending for short) is a method of mixing and processing the flue-cured tobacco of different grades, different origins, different parts, different years, and different batches according to a certain matching rati...
