Cigarette formula design method and device based on main components and style quality and storage medium

The invention discloses a cigarette formula design method and device based on main components and style quality and a storage medium. The method comprises the steps that the flavor type, conventional chemical components, style value, quality value, price cost, stock, production year, production place and grade data of to-be-used single-grade tobacco leaves are obtained; performing preliminary screening by setting constraint conditions of cost, feeding amount and tobacco leaf production years to form a candidate tobacco leaf set; dividing the candidate tobacco leaf set into four subsets according to the aroma types of the tobacco leaves; setting a grade number constraint condition; representing a formula design target as a planning problem; based on a grade number constraint condition and a planning problem, the grade number of the tobacco leaves of each flavor is selected from the four subsets, and a formula is formed through combination; the formula is subjected to proportion optimization, so that the formul
