考虑了需求不确定情况下由多个阶段组成的按订单制造系统的生产控制策略。在每个阶段进行特定于订单的操作可以用相同的原材料生产多种最终产品。一个阶段每个周期的生产数量取决于工作量。为了缩短交货时间，允许在没有确认订单的情况下在上游阶段开始生产，将半成品保留在系统内按库存生产，然后在规格和数量的约束下将订单与这些产品进行匹配。通过结合缓冲区选择规则、匹配接受规则和按库存补货规则，制定了八种按库存生产策略。他们的表现是通过计算机模拟进行评估的。在产能相对有限的情况下，从订单的平均延迟时间和按库存生产的平均库存水平来看，积极地将订单与按库存生产的产品匹配是更可取的。通过计算工作负载并考虑计划订单数量来仔细加载以避免不希望的处理延迟的策略，在增加的生产能力下明确获得更好的结果。
Production control policies for a make-to-order manufacturing system composed of several stages under uncertain demand are considered. Conducting order-specific operations at each stage can produce a variety of final products from the same raw material. The production quantity per period at a stage depends on the workload. To shorten lead times, it is permitted to start production at upstream stages without confirmed orders, hold semi-finished items within the system as make-to-stock, and then match orders to these items under the constraints of specifications and quantities. Eight make-to-stock policies are prepared by combining buffer selection rules, matching acceptance rules, and make-to-stock replenishment rules. Their performance is evaluated via computer simulation. In the case of relatively limited capacity, aggressively matching orders to make-to-stock items are preferable in terms of the average lateness of orders and the average inventory level of the make-to-stock items. A policy that loads carefully to avoid undesirable processing delay by calculating the workload and considers the planned order quantities explicitly obtain better results under increased production capacity.
