以一个经销季节性商品的零售商为研究对象,通过引入考虑零售商风险态度的谱风险测度,分析了期权契约机制下具有不同风险偏好零售商的最优订购策略.通过建立期权契约机制下基于零售商谱风险测度的商品订购决策模型,分析得出零售商的最优现货订购量和期权订购量存在并且唯一;并进一步结合均值-CVaR风险谱函数,研究了在此风险测度下不同风险偏好零售商的具体订购策略,揭示了零售商风险态度、期权契约等对其最优订购策略的影响;最后通过数值实例对模型的求解过程和理论结果进行了验证分析. Taking a retailer who sells seasonal merchandise as the research object, this paper analyzes the optimal ordering strategy of Retailers with different risk appetite under the option contract mechanism by introducing the spectral risk measure which takes the retailer’s risk attitude into account. By establishing the option contract mechanism, Retailer spectrum risk measure of product order decision-making model, the analysis shows that the retailer’s optimal spot order quantity and option order quantity exist and are unique. Furthermore, combining the mean-CVRR risk spectrum function, we study the different risk appetite The retailer’s specific ordering strategy reveals the influence of retailer’s risk attitude and option contract on its optimal ordering strategy. Finally, the numerical example is used to verify the model’s solution process and theoretical results.
