1. A product production planning method, comprising:
determining material types of materials, the material types including a first type of old materials and a first type of new materials;
determining a production plan of products to be produced based on the old materials of the first type and the new materials of the first type included in the materials, according to a linear programming model and the material types;
wherein the linear programming model includes a constraint condition and an objective function;
the production plan includes a first-stage production plan and a second-stage production plan, the first-stage production plan is a production plan for producing products to be produced according to the old materials of the first type, and the second-stage production plan is a production plan for producing products to be produced according to the new materials of the first type:
wherein the objective function is an objective function that maximizes a product output of first sub-products and maximizes a product output of second sub-products; the first sub-products are products planned to be produced in the first-stage production plan; and the second sub-products are products planned to be produced in the second-stage production plan;
wherein determining the production plan of the products to be produced according to the linear programming model and the material types includes:
determining the first sub-products and the second sub-products according to the material types;
allocating materials for the first sub-products according to the linear programming model to determine the first-stage production plan;
updating constraint conditions of the linear programming model according to the first-stage production plan; and
allocating materials for the second sub-products according to the updated linear programming model to determine the second-stage production plan.
