研究基于预付账款融资模式下的供应链金融三方决策问题,采用CVaR的风险度量准则作为决策标准,建立了随机需求下的单个风险规避零售商、单个风险规避制造商及单个风险规避银行组成的供应链金融风险模型.在权衡收益和风险的基础上,得出零售商的最优订购量、制造商的最优批发价格及银行的最优利率.研究以零售商是否存在违约为前提,通过对三方收益的分析,在考虑风险规避水平的同时,求解出最优订购量、批发价格和利率,并研究它们之间的关系.最后,通过Matlab数值仿真验证预付账款模式下CVaR模型的合理性.
Based on the three-sided decision-making of supply chain finance under the mode of prepay financing, this paper uses CVaR risk measurement as a criterion to establish a single risk-averse retailer, a single risk-avoidance manufacturer and a single risk-averse bank under random demand Supply chain financial risk model.Based on the tradeoff between gains and risks, the optimal order quantity of retailers, the optimal wholesale price of manufacturers and the optimal bank interest rate are obtained.Studying the existence of defaults on retailers, In the analysis of the three-party revenue, considering the level of risk aversion, the optimal order quantity, the wholesale price and the interest rate are solved and the relationship between them is studied.Finally, the numerical simulation of Matlab verifies the reasonableness of the CVaR model Sex.
