Model and algorithm for integrated charge plan in the steel industry

According to the demand of integrated production and the characteristic of charge plan in the steel industry, firstly, use graph theory to describe charge plan; secondly, a bi-objective charge plan model is introduced in detail considering weight range, flow limitation and other factors; To solve this model, a two-phase heuristic algorithm (THA) is introduced, which deals with the simple graph with vertex clustering method firstly, and then design a novel probability match algorithm to solve the optimization model; Finally, the simulation with large-scale production data shows that the model and algorithm is feasible.
