Abstract: This study takes the production scheduling of industrial enterprises in the tobacco industry as an entry point, analyses the production scheduling process of H cigarette factory, and takes the inventory-to-sales ratio (ISR) scheduling strategy in the production scheduling process as the main object of analysis. With the goal of meeting market demand and reducing the inventory of finished cigarettes, a mathematical model of production scheduling according to the ISR is constructed, and the maximum and minimum ISRs can be calculated. Combined with the knowledge graph model, a reasonable production scheduling strategy for the inventory-sales ratio is formulated. Combined with the annual inventory and sales ratio data of the tobacco industry and the capacity of the enterprise's wrapping machine, the model is optimised to reduce the number of inventories and reasonably use the capacity of the wrapping machine, so as to make the annual production quantity relatively balanced.

Keywords: ISR; inventory-to-sales ratio; scheduling strategy; knowledge graph; packing machine capacity; inventory.
