Production scheduling is one of the key technologies in steel manufacturing process.It plays a significant role in reducing the production cost and improving the production efficiency of iron and steel enterprises.In recent years,with the rapid development of intelligent steel-manufacturing technology,production scheduling has attracted increasing attention and become a research hotspot in the field of iron and steel metallurgy.The process of production scheduling in the process of steelmaking-continuous casting was summarized and discussed through reviews of previous researches,and the characteristics and application scopes of various methods were compared and classified.Typical cases of the computer-aided scheduling system in domestic and overseas steelmaking plants were discussed,and the characteristics of each system were studied and analyzed comparatively.On the basis of the previous studies,forwardlooking strategies and a methodology of production scheduling were proposed for the future study of steelmaking-continuous casting process.For static scheduling,a new concept"rules+algorithm"was proposed,and a scheduling model construction method based on the production mode optimization of a steel mill was developed for a domestic special-steelmaking plant as a case study.For dynamic scheduling,multi-process collaboration was suggested,and a collaborative control method based on multi-agent was proposed.This method was developed for multi-process control,quality control,and scheduling control of the steelmaking-continuous casting process.An optimized and effective method for modeling and solving is one of the important means to solve the production-scheduling problem,aiming at improving the levels of setting up production plan and the feasibility of production planning.Meanwhile proposed method for modeling and solving can strengthen the on-site real-time control in steel mills and is of great significance to realize stable,orderly,and continuous operation in steelmaking-continuous casting process.
