Simulating Schedule Optimization Problem in Steelmaking Continuous Casting Process
This paper establishes the models of the steelmaking continuous casting (SCC) process, and proposed the improved algorithms for this problem. The simulation results of a computerized scheduling system are also given to prove the model. The SCC process scheduling problem is very difficult to get a good performance solution in practice. The scheduling of the SCC process requires that each cast pl...
متن کاملA mathematical programming model for scheduling steelmaking-continuous casting production
This paper presents a mathematical model, based on the just-in-time (JIT) idea, for solving machine con ̄icts in steelmaking-continuous casting (SCC) production scheduling in the computer integrated manufacturing system (CIMS) environment. The model is developed as a non-linear model based on actual production situations, considering both punctual delivery and production operation continuity. It...
متن کاملScheduling High-Grade Steelmaking
The paper describes a scheduling system for a high-grade steel making plant. Because very specialized steel grades are produced the variety of the chemical analysis of the heats is very high and the lot sizes are small. One of the most constraining factors in the production is the infiltration of chemical elements between consecutive heats in the electric arc furnace. To find a schedule that vi...
متن کاملSteelmaking and Casting
Thin slab casting and rolling was originally developed as a low cost alternative to a conventional casting and rolling process route. However, due to the technological restrictions of the first generation plants, only limited quality and productivity goals could be achieved, questioning its further application to more advanced applications. This paper describes the original contributions that D...
متن کاملComplete Modification Rescheduling Method and Its Application for Steelmaking and Continuous Casting
Delayed processing time and machine failures upset the plan in steelmaking-continuous casting (SCC) production, which make production plan infeasible. The manual repairing cannot satisfy objectives of quick response and optimal scheduling. The practical rescheduling with 1-4 refining stages cannot abstract as three stages hybrid flow shop (HFS). A method is presented for the rescheduling proble...
