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
