【摘要】 结合宝钢热轧厂计划编制的实际情况,考虑板坯轧制区段对轧制表面等级的约束和板坯出炉温度、精轧温度、卷取温度对计划单元的影响,建立了热轧计划编制的数学模型.提出将计划单元个数预估计作为模型求解的初始步骤,采用基于启发式和演化计算结合的混合算法,将不可行个体转换为标准可行个体后再进行演化处理.仿真试验表明该热轧计划编制方法能够达到较好的应用效果.更多还原

【Abstract】 Constraints between rolling section and surface grade in a plan unit and impacts due to temperature of discharging,finishing milling and coiling are considered in the practice in hot rolling factory.A rolling plan model which regards estimation of the number of plan units as the initial process is suggested.A hybrid algorithm based on heuristic evolutionary computation is proposed.The evolutionary operation is worked after infeasible individuals are converted into standard feasible solutions.A simulation result with real production data from Baoshan iron and steel company limited,Ltd shows that the model and algorithm suggested are feasible.更多还原
