炼钢热轧一体化生产与物流计划模型及求解

合理的板坯与热轧卷库存、缩短产品的生产周期、降低能源消耗、按合同交货以提高客户满意度已成为钢铁生产管理的要求.为了降低生产与物流成本,本文针对炼钢与热轧生产及其衔接方式的特点,考虑能力和两个阶段冲突约束条件下构建生产与物流计划层次的一体化模型.分析了无能力约束和允许延迟条件下热轧批量的极点特征,对原问题采用Dantzi...

Modeling and solution to integrated production and logistics planning of steel making and hot rolling

Reasonable inventories of steel slabs and hot-rolled coils,shortening production cycles,reducing energy consumption and improving customer's satisfaction by delivering goods on contracts are requirements in operations management in iron and steel industry.To reduce the production and logistics costs,considering different capacities and conflicting constraints,this paper present an integrated production and logistics planning model based on the characters of production and connection between steel making and...
