通过签订长期供应合同，买家寻求降低采购成本，并确保产品不间断地交付。当有长期合同时，供应商寻找新客户的压力较小，并且可以收取低于现行现货市场价格的价格。我们研究了一个公司的采购决策中存在的能力保留合同，这家公司使其长期供应商除了现货市场的替代品。该合同要求交付保留的固定容量的任何所需部分，以换取买方的保证付款。我们研究了两种不同类型的定期审查的库存控制策略下，双方的理性行为的买方：两个号码的政策，和基本库存政策。当考虑典型的需求概率分布时，在买方的采购计划中包含现货市场源显著降低了长期供应商的容量承诺。(C)2001 Elsevier Science B.V. Ah版权所有。
By committing to long-term supply contracts, buyers seek to lower their purchasing costs, and have products delivered without interruption. When a long-term contract is available, suppliers are less pressured to find new customers, and can afford to charge a price lower than the prevailing spot market price. We examine sourcing decisions of a firm in the presence of a capacity reservation contract that this firm makes with its long-term supplier in addition to the spot market alternative. This contract entails delivery of any desired portion of a reserved fixed capacity in exchange for a guaranteed payment by the buyer. We investigate rational actions of the two parties under two different types of periodic review inventory control policies used by the buyer: the two-number policy, and the base stock policy. When typical demand probability distributions are considered, inclusion of the spot market source in the buyer's procurement plan significantly reduces the capacity commitments from the long-term supplier.
