针对热轧型钢企业生产计划调度的约束复杂、易延误交货期、寻求最优解困难等问题，提出生产计划调度系统的结构功能设计方案，选用改进的批决策批调度策略建立计划调度模型，并利用遗传算法求解生产调度计划。以某热轧型钢企业设计实现的制造执行系统为依托，研究生产计划调度系统的执行情况，通过不同的订单数据以及不同的计划编制方法进行模拟计算和结果比较，验证了该改进型批决策与批调度模型的解可降低设备调度、节省生产时间、减少交货延误，以此来指导热轧型钢的生产可切实提高企业生产效率。

The planning and scheduling of hot rolling section steel production have the difficulties in complex constraints,being prone to put off the delivery date and hard to explore the optimal solution,etc.In light of these,we put forward a design scheme for production planning and scheduling system structure and function.In it the improved batch decision-making and batch scheduling strategy is chosen to establish the planning and scheduling model,the genetic algorithm is employed to solve the production scheduling plan.Based on a manufacturing execution system designed and implemented for a hot rolling section steel enterprise,we study the execution situation of the production planning and scheduling system,and carry out simulative calculation and outcomes comparison using different order data and various plan formulation approaches.It is verified that the solution of the modified batch decision-making and batch scheduling model is able to save production time,reduce the times of equipment scheduling,and reduce the times of delay in delivery.It can feasibly improve the production efficiency of the enterprises by using the model to guide the production of hot rolling section steel.
