Managing Capacity and Inventory Jointly in Manufacturing Systems
针对单产品单工位的按库存生产系统,在产能成本远高于惩罚和持有成本的渐近条件下,开发近似方法联合优化产能与库存,并揭示最优库存策略如何随产能投资变化。
In this paper, we develop approximations that yield insight into the joint optimization of capacity and inventory,and how the optimal inventory policy varies with capacity investment in a single-product, single-station, make-to-stock manufacturing system in which inventory is managed through a base-stock policy. We allow for a correlated demand stream as we analyze our models in an asymptotic regime,in which the penalty and holding costs are small relative to the cost of capacity. Although our approximations are asymptotically correct,our Brownian approximation is accurate even under moderate traffic intensity.
