A new warehouse delivery configuration method is proposed for the delivery configuration optimization problem of component parts of complex product of different orders in discrete processing and assembly enterprises. It takes on time delivery and minimum loss of order as the evaluation criterion. It is based on the current production status to find out the longest remaining production line in the processing and assembly process. The priority level of deployment is determined by inventory status and the importance of the order. In conclusion corresponding optimal delivery configurations are developed by the mode of delivery in whole order and the mode of delivery in several times.
