考虑一个供应商与一个零售商组成的单一时段、单一产品的两层供应链模型.供应商提供基于期权的数量柔性契约,零售商将条件在险价值作为其风险度量准则.首先得到了零售商的初始订货量及期权购买量与风险厌恶程度之间的解析表达式,并分析了解的性质;然后通过数值实验分析了风险厌恶程度及各个系统参数对最优决策及最优利润的影响. Consider a one-time, single-product two-level supply chain model consisting of a supplier and a retailer. The supplier provides a flexible contract based on the quantity of the option, and the retailer uses the conditional on value as a risk measure. First, the retailer The initial order quantity, the purchase quantity of options and the degree of risk aversion are analyzed and the nature of the understanding is analyzed. Then, the degree of risk aversion and the influence of each system parameter on the optimal decision and the optimal profit are analyzed through numerical experiments.
