Hybrid flowshop scheduling model and its genetic algorithm

With the non-breakable feature in steel product making, an integrative scheduling model was presented. The object was to minimize the flow span time and the wait time between working steps. One furnace was counted as one working piece and several furnaces were regarded as one cast. By using the improved genetic algorithm, a cast scheduling table and a subsequent Gantt chart described the results. A group of typical testing data validated the results.
