Optimum Steelmaking Cast Plan with Unknown Cast Number Based on the Pseudo TSP Model

An optimum furnace cast plan model for steelmaking continuous casting planning and scheduling with unknown cast number is presented. Based on the analysis of the difficulties to solve the problem, a pseudo travel salesman problem (TSP) model is presented to describe the plan and scheduling model. An improved particle swarm optimization with variant particle is presented to solve the optimum charge plan problem. Simulations have been carried and the results show that the pseudo travel salesman problem is very fit for describe the model. The computation with practical data shows that the model and the solving method are very effective.
