考虑一家公司在专用生产线上生产多个产品(阶段1)，这些产品在共享资源(阶段2)上进一步定制/校准，这对所有产品都是通用的。专用生产线和用于校准的共享资源面临着产能不确定性。该公司持有尚未校准的产品库存，并在收到订单时进行校准。分析了两种产品的多周期库存模型，得到了第一阶段的最优生产策略和第二阶段需求的共享资源的最优分配。对于共享资源，由于其能力的不确定性，不仅影响计划的生产总量，而且还影响产品的加工顺序。我们刻画了共享资源的最优分配，并证明了最优策略使产品的期末库存尽可能接近所谓的“目标路径”。对于专用生产线来说，因为它们的产能……
Consider a firm that produces multiple products on dedicated production lines (stage 1), which are further customized/calibrated on a shared resource (stage 2), common to all products. The dedicated production lines and the shared resource for calibration face capacity uncertainties. The firm holds inventory of products that are not yet calibrated and carries out calibration when an order is received. We analyze a multiperiod inventory model for two products and derive the optimal production policy at stage 1 as well as the optimal allocation of the shared resource to demands at stage 2. For the shared resource, because of its capacity uncertainty, not only the total planned production quantities matter, but also the sequence in which the products are processed. We characterize the optimal allocation of the shared resource and show that the optimal policy keeps the ending inventories of products as close to a so-called “target path” as possible. For the dedicated production lines, because of their capacit...
