Dynamic scheduling optimization method for steelmaking and continuous casting based on Flexsim
In the process of steelmaking and continuous casting,there will be many disturbances,resulting in the scheduling can not be carried out according to the original plan in many times,so it is necessary to adopt real-time scheduling strategy for dynamic scheduling of steelmaking and continuous casting production process.In order to ensure the stability of steel-making and continuous casting process,a dynamic adjustment method based on"adjustable"buffer time and Flexsim backward working method was proposed.The rescheduling job plan was generated by adding restrictions such as crane rules,equipment selection rules,and ladle quantity limits.Through the optimized dynamic scheduling scheme,the influence of the disturbance in the process of steelmaking and continuous casting was well eliminated.In addi-tion,comparing the present research scheme with the manual scheduling in terms of evaluation indexes such as equip-ment utilization,degree of continuity and production cycle time,the average production cycle time was reduced by 7.9 min and the degree of continuity was increased by 8.8％.The results show that this method can not only dy-namically generate specific scheduling schemes based on rules and Flexsim,but also significantly improve the related indexes of the process,which provides a theoretical basis for Flexsim to guide field production in the future.
