摘　　要：针对按订单生产(MTO)下的多工序、多路径的钢铁生产中订单投放问题建立数学模型,提出了度量订单交货提前/拖期程度、负荷均衡程度以及工序生产紧密衔接程度的3个指标.针对问题的模型及其特点,提出了基于负荷均衡的订单投放算法.首先基于负荷控制的思想为订单池中的订单指定生产路径;然后基于瓶颈工序优先均衡的原则调整工序负荷;最后对非瓶颈工序进行负荷均衡.基于企业实际生产背景的仿真实验结果验证了模型和算法的有效性.A mathematical model is established for order release in the make to order（MTO） steel enterprise with multi- production stage and multi-production route. Three indexes are built to measure the degree of delivery in advance or delay, the balance of workload, and the continuity of production in adjacent stage. According to the model and the characteristics of the problem, an order release algorithm based on workload balance is proposed. Firstly, the production routes are assigned for the orders in the order pool based on work load control（WLC）. Then the workload of machines is coordinated based on the principle of the bottleneck stages. Finally, the load on non-bottleneck machines is balanced. The simulation experiments verify the effectiveness of the model and the algorithm.
