将炼钢批量计划问题转化为一个约束满足问题处理，建立问题的约束满足模型，给出了基于约束满足的求解算法。仿真实验证明了模型和算法是有效的。关键词:炼钢-连铸-热轧；炼钢批量计划；约束满足；约束传播；ABSTRACT: Steelmaking batch planning problem is treated as a constraint satisfaction problem. A constraint satisfaction model is established, solving algorithm based on constraint satisfaction technology is given. The validity of the model and algorithm is demonstrated by the simulation experimentKEYWORDS: steelmaking-continuous casting-hot rolling; heating plan; steelmaking batch plan; constraint satisfaction problem; constraint propagation
