炼钢-连铸生产启发式调度方法
Heuristic scheduling method for steelmaking and continuous casting production process
摘要
Abstract
There are multi-converter, multi-refining machine and multi-continuous caster, multi-stage refining and reen-trant line in the steelmaking-continuous casting (SMCC) production process, which leads to the difficult scheduling. Exist-ing scheduling researches only focus on simple production mode and are difficult to apply to the actual production process. Manual scheduling method is low efficient and easily leads to too long waiting time, the molten steel temperature drop, and even causes casting break. The paper researches the scheduling problem of SMCC production process in the largest iron and steel company (BaoSteel) in China. A variety of scheduling sequence methods and equipment assignment methods are proposed. Many heuristic methods are studied by means of simulation experiments for various scheduling sequence methods and multi device assignment methods. At the end of this paper, the best proposed method is applied to the SMCC production in the large iron and steel enterprises. The real-time application show that the proposed method can dramatically shorten the redundant waiting time for molten steel.关键词
