有充分的证据证实，在主要供应来源不可避免地中断时，后备采购十分重要。如何与备用供应商合作，以确保在主要来源出现短缺时的备用或应急供应，这一问题已受到极大关注。我们研究了当主供应商的中断风险存在不确定性时，买方和备用供应商之间的容量预留合同。此外，我们考虑的约束，要求买方订购或者没有或至少有一个最低订货量的情况下，应急采购。通过签订这种备用合同，买方寻求降低其或有采购成本，并确保在存在风险的情况下商品的供应。从理论上研究了参与者的最优决策，并对关键参数和特殊情景的影响进行了数值评估。该研究有助于文献提供了一个更好的理解，如何使用容量预留合同作为一种工具，以建立长期的关系，在备份采购和中断的不确定性和应急供应的影响。(C)2016爱思唯尔有限公司版权所有
Ample evidence has confirmed the importance of backup sourcing when disruption of the major supply source is inevitable. The decisions associated with how to work with the backup supplier to ensure backup or emergency supply when the primary source experiences shortfall have received a great deal of attention. We study a capacity reservation contract between a buyer and a backup supplier when there is uncertainty about the major supplier's disruption risks. Additionally, we consider the constraint that requires the buyer to order either none or at least a minimum order quantity in the case of contingent sourcing. By committing to such backup contracts, the buyer seeks to lower its contingent purchasing cost and to ensure the availability of merchandise in the presence of risks. The involving players' optimal decisions are investigated theoretically and the impacts of the key parameters and special scenarios are assessed numerically. The study contributes to the literature by providing a better understanding of how to use a capacity reservation contract as a vehicle to build long-term relationship in backup sourcing and of the impacts of disruption uncertainty and contingent supply availability.
