In today's competitive markets, a company able to fill customer orders quickly, as well offer a variety of custom products will have an advantage. However, these goals place conflicting pressures on manufacturers. To fill orders quickly requires firms to carry finished goods inventory - but this carries a risk of holding in inventory items not suitable for customer orders. To provide custom products, firms typically produce items only when the customer places an order. This reduces the risk of not selling items made ahead of time, but causes longer customer lead times. For this reason, many firms use a hybrid approach. They produce semi-finished goods ahead of customer demand (make-to-stock), and then customize the semi-finished goods when customer orders materialize (make-to-order). The first thrust area of this research deals with enhancing our understanding of production systems where products are made in this hybrid fashion. The focus is on exploring the use of various inventory control policies and production structures for these hybrid systems.

在当今竞争激烈的市场中，能够快速完成客户订单并提供各种定制产品的公司将具有优势。然而，这些目标给制造商带来了相互矛盾的压力。为了快速完成订单，企业需要持有成品库存，但这也带来了库存项目不适合客户订单的风险。为了提供定制产品，公司通常只有在客户下订单时才生产产品。这减少了不提前销售产品的风险，但会导致更长的客户交货时间。出于这个原因，许多公司采用混合方法。他们在客户需求之前生产半成品（定制库存），然后在客户订单实现时定制半成品（定制订单）。本研究的第一个重点领域涉及提高我们对以这种混合方式制造产品的生产系统的理解。重点是探索这些混合系统的各种库存控制政策和生产结构的使用。
