摘要
首先建立了两流薄板坯连铸连轧流程生产调度规则库.然后根据该生产流程的特 点,提出了遗传算法新的编码、交叉、变异操作及改良的概念,并在遗传算法的初始种群建立 和改良过程中引入调度规则.在此基础上,利用调度规则和遗传算法相结合的混合遗传算法 建立了两流薄板坯连铸连轧流程生产调度系统.该调度系统可以较好地解决两流薄板坯连 铸连轧流程的动态调度问题,进一步优化生产组织.
Schedule rules for two-strand thin slab casting and rolling were established. Based on the characteristic of the casting and rolling process, a kind of coding, crossover operator, mutation operator and the concept of amendment operator for the genetic algorithm were proposed. In the genetic algorithm, the schedule rules were introduced into the modeling of initial population and the operation of amendment. A scheduling system of two-strand thin slab casting and rolling was developed by using the schedule rules and the genetic algorithm. This system can solve the dynamic schedule problem of two-strand thin slab casting and rolling and optimize production management.
