许多公司正在探索生产和供应链战略时，客户可能会被划分为不同的类的基础上的服务水平或优先级。这种细分可以导致更有效的生产系统以及更好的供需匹配。在这项研究中，我们分析了一个系统与客户类1和2，其中客户类1具有较高的优先级，履行比客户类2在同一时期。我们开发了一个最佳的生产和库存策略，配给当前和未来的有限能力之间的客户类1和2，通过储备库存的未来和接受订单，现在为未来的交付时，需求和生产是一般的随机函数。我们证明了一个修改的订单最多的政策（S*，R i*，B i*）是最优的在每个时期。S* 是期初生产后的目标库存水平; R 1* 表示要保护的最佳库存量，以防止销售给两个类别，R 2* 是要保护的额外库存量，以防止类别2。B 2* 是通过欠拨可用于两个类别的未来容量的最优量，并且B 1* 是类别1的附加欠拨量。计算分析表明，差异化策略可以导致一个显着的利润改善比传统的库存政策。
Many firms are exploring production and supply chain strategies when customers may be segmented into different classes based on service level or priority. Such segmentation can result in a more efficient production system as well as a better match between supply and demand. In this research, we analyze a system with customer classes 1 and 2, where customer class 1 has a higher priority of fulfillment than customer class 2 in the same period. We develop an optimal production and inventory strategy that rations current and future limited capacity between customer classes 1 and 2, through reserving inventory for the future and accepting orders now for future delivery when demand and production are general stochastic functions. We show that a modified order-up-to policy (S*, R i*, B i*) is optimal in each period. S* is the targeted inventory level after production at the beginning of the period; R 1* represents the optimal inventory to be protected from being sold to both classes, and R 2* is the additional amount of inventory to protect from class 2. B 2* is the optimal amount of future capacity to make available to both classes through backlogging, and B 1* is the additional backlogging amount for class 1. Computational analysis shows that the differentiation strategy can result in a significant profit improvement over a traditional inventory policy.
