A Note on Bounds for Direct Shipping Cost
利用Gallego和Simchi-Levi提出的直接运输成本界限，证明即使直接运输的最优装运量是满载，也难以排除多站库存路径策略。
The bounds on direct shipping cost developed by Gallego and Simchi-Levi are used in this note to demonstrate that it is difficult to rule out multiple stop inventory-routing strategies, even when the optimal shipment size for direct shipping is a full vehicle.
