Scheduling And Process Monitoring System Of Steelmaking-Refining-Continuous Casting Production

In the production process of steel enterprises, the optimization of production planning and scheduling is an important way to achieve high quality and low price, prompt delivery of their products, and steelmaking-continuous casting is the bottleneck in steel production. Production scheduling is defined scientifically that can determine the full large-scale equipment to improve production efficiency, reduce the waiting time processes, improve equipment utilization and increase capacity.Steel production scheduling planning is scheduled widely by the artificial, the effect of the implementation of the planning is not intuitive and understandable, further more, it is difficult to determine the preparation of a scheduling planning is optimal or better. It is easy to cause solidification of molten steel, continuous-casting off water. Therefore, it is necessary to simulate the production planning, by viewing the simulation results of the study will be able to review that the plan is good or bad, and rectify the better production plan.In this paper, firstly, according to the feature of steelmaking-refined-continuous casting production logistics, simulation object model were established in the use of simulation modeling technology Java language and Witness software. In the development of steelmaking-refined-continuous casting scheduling and simulation optimization system made a series of evaluation factor to determine that the resource utilization of steel enterprises are reasonable. Secondly, with the simulation function of Witness simulation software, the production scheduling planning were simulated and optimized in the function of backward time. The better scheduling planning is obtained, re-evaluation that the second simulation results are reasonable, and determine the optimal scheduling planning.Through statistical analysis of simulation data shows that the system can achieve the function of scheduling planning simulation in the enterprise information system framework. For the optimization problem of shop scheduling, a simulation overcome the defect of the mathematical description in the scheduling problem, and the evaluation factor based on analysis can be used in the simulation results in the steelmaking shop scheduling optimization program.
