A Two-Echelon Inventory System with Priority Shipments
分析了一个备件的两级库存系统，允许在缺货时使用优先库存池来加快服务，并提出了一个可处理的聚合模型及其分解近似方法，附有计算机测试结果。
A two-echelon system for spare parts is analyzed. The system allows the use of priority inventory pooling to expedite service when a stock-out occurs. First, a tractable aggregate model is derived. This model is then disaggregated to approximate the performance of the exact system. Results of computer tests are also presented.
