Abstract: Order-oriented production is not only satisfactory to maximize the profit，but also to the due date of customer order.In such circumstances，scheduling orders has been an important decision in modern enterprise.Delivery date decision of orders for multiple assembly lines is studied.An assembling cost model of electronic product orders is constructed.By analyzing customer importance，delivery urgency，order profit and calculating order priority value，the sequence of scheduling orders is given.Assembly scheduling method for multiple assembly lines based on order priority rule is proposed，considering constraint of assembly resources and delivery date.According to customer importance，all orders are divided into two groups.A group of orders with more importance is scheduled by backward scheduling method，and other group is scheduled by forward scheduling method.The application demonstrates the efficiency of the proposed model and solution algorithm.Enterprise maximizes total profit and delivers production to significant customer on time.

Key words: delivery-date decision, order priority rule, two-way scheduling method

摘要： 如何安排订单生产使得企业在获得最大效益的同时，也要满足客户对订单的交货期要求，这已经成为当今企业的一项重要决策问题。研究了多装配线情况下的订单交货期决策问题，建立了电子产品订单排产成本模型。通过对客户重要性、交货紧迫性和订单效益的分析计算，确定订单的优先执行顺序准则。基于订单优先准则，考虑装配资源约束和交货期约束，提出了多装配线条件下的装配模拟排产方法，根据订单的重要与否分为两类订单，分别采用后向排产方法和前向排产方法。应用实例的计算分析表明提出方法的有效性，企业获得较大效益并且能够满足重要客户的交货期要求。
