In this paper, we consider the capacity requirements allocation problem of a buyer between an incumbent supplier and a new supplier over a two-period horizon. The buyer allocates some of its capacity requirements to the incumbent supplier in the first period. This enables the incumbent supplier to reduce its cost in the second period due to the phenomenon of production learning. The buyer also makes supplier development investments in the new supplier in the first period. In addition, both the incumbent and the new entrant make process improvement efforts in the first period, which enhance the effective capacity available in the second period. Finally, the buyer allocates the rest of its capacity requirements between the two suppliers in the second period. We find that the buyer has various sourcing strategies to maintain a competitive supply base. We also find that the optimal supplier development investments and sourcing strategies depend on the collaboration relationship between the buyer and the new supplier.

供应商开发投资下的战略采购

在本文中，我们考虑了在两个时期的范围内，现有供应商和新供应商之间的买方的能力需求分配问题。买方在第一期将其部分产能需求分配给现任供应商。这使得现有供应商能够在第二期由于生产学习现象而降低成本。买方还在第一期对新供应商进行供应商开发投资。此外，在职者和新进入者都在第一阶段进行了流程改进工作，从而提高了第二阶段可用的有效能力。最后，买方在第二个期间在两个供应商之间分配剩余的产能需求。我们发现买方有各种采购策略来维持有竞争力的供应基础。
