We consider a supplier-buyer supply chain. The buyer holds private forecast information (high/low), and the supplier offers a menu of capacity reservation contracts to align incentives. We analyze how the menu of contracts should be adapted when lifting the assumptions that buyers act rationally and/or that buyers’ utility is deterministic. We employ a novel choice-based optimization approach that integrates a multinomial logit model (capturing the buyer’s contract choice behavior) with a mixed-integer nonlinear program. The choice-based optimization model can be solved with off-the-shelf solvers and is therefore ready to use by management. We further derive qualitative insights on how to adapt existing contracts in a numerical study. We show that cutting off low-demand buyers, reducing reservation fees in a specific manner and introducing more contract options may increase suppliers’ and supply chains’ performance.

基于选择的供应链合同优化方法
我们考虑供应商-买方供应链。买方持有私人预测信息(高/低),供应商提供容量预留合同菜单以调整激励措施。我们分析了在解除买方行为理性和/或买方效用是确定性的假设时应如何调整合同菜单。我们采用了一种新颖的基于选择的优化方法,该方法将多项 logit 模型(捕获买方的合同选择行为)与混合整数非线性程序相结合。基于选择的优化模型可以使用现成的求解器求解,因此可供管理层使用。我们进一步得出关于如何在数值研究中调整现有合同的定性见解。我们表明,切断低需求买家,
