Integrated production charge plan optimization method based on slab clustering

The invention relates to the technical field of steel hot production optimization, and provides an integrated production charge plan optimization method based on slab clustering. The method comprisesthe following steps: step 1, constructing a charge plan optimization model; step 2, classifying the to-be-planned slab set according to steel grades and thicknesses to obtain a plurality of primary classes, and the steel grades and the thicknesses of the slab in each primary class being the same; step 3, clustering each primary class to obtain a plurality of secondary classes; step 4, assigning atundish to the slab in each secondary class, so that the weight of the slab cast by the tundish is maximized; step 5, determining the width of the slab in each tundish; and step 6, the slab in each tundish being subjected to charge division. According to the method, a stable and better charge plan can be quickly obtained under the condition of large-scale furnace assembly, the tundish utilizationrate and the production eff
