MTO 运营模式的订单交货期决策模型

摘要

承诺交货期过晚，没有时间优势，容易丢失订单；承诺交货期过早，企业超负荷生产，增加生产成本，可能出现亏损。针对基于订单式生产（ MTO）的中小制造企业的客户订单交货期预报问题，综合考虑价格、订单需求量、提前完工和延期交货损失、加班、外协和损耗率因素等对任务完工期的影响，以收益最大化为目标，建立了订单任务交货期决策模型，并运用Matlab编程和计算工具对实例进行分析，验证了模型的有效性。模型对MTO生产企业交货期决策具有一定的参考意义。%In manufacturing enterprise , if product delivery date is set to be too late , an enterprise would lose its costumer order because of the lack of deliver time advantage .However , if the delivery date is set to be too early , enterprises would have deficit because of overload and increased cost .To predict order deliv-ery date for small and medium-sized manufacturing enterprises operating in a make-to-order mode , price , demands, earlier completion, later delivery, overtime work, association, loss rate, and so on are ana-lyzed.Then, with income maximization as objective , a delivery-income model is presented .By using Mat-lab, a real-life case problem is given to verify the usefulness of the model .Results show that extending the due date by effective strategies , such as pricing strategies , all orders can be done by regular and overtime production .The due date that corresponds to full capacity is the optimal promised delivery time in the sense of gain maximization .
