Quality improvement-oriented tobacco leaf curing process optimization method, system and terminal

The invention belongs to the technical field of tobacco leaf curing, and discloses a tobacco leaf curing process optimization method and system for quality improvement and a terminal, and the method comprises the steps: assigning scores to tobacco leaves in different states according to the quality characteristic indexes of the tobacco leaves in different batches, and classifying the scores; summarizing the typical process and process stage process control data into a flow chart, and converting a baking process directed graph according to the flow chart; based on the historical baking data and the ultimate score of the expert, assigning a score to a baking process stage involved in the baking process directed graph, and converting the score into a weight of a directed line; and according to the baking process directed graph, a Dijkstra algorithm is used, and the most suitable tobacco leaf baking process path is screened according to the principle that the sum of weights is maximum. According to the method, re
