针对随机需求条件下,供销双方均有风险规避特性时,供应商管理库存(VMI)契约的优化与协调问题,通过收益共享契约,利用条件风险值理论(CVaR),建立了基于负收益的条件风险值模型和基于条件风险值最优订购量和供应量模型,实现了零售商、供应商和供应链完美协调,得出了考虑风险规避的供应商管理库存(VMI)契约模型,揭示了契约模型中的供销双方风险规避水平(βs,βr),单位持有成本比率(C),单位收益份额(r),单位剩余补偿比率(λ)之间内在相互关系。
Aiming at the optimization and coordination of VMI contracts under the condition of stochastic demand and supply and demand sides both have the risk aversion characteristics, through the revenue-sharing contract and the conditional risk value theory (CVaR), the conditions of negative returns Risk value model and the optimal order quantity and supply model based on conditional risk value, the perfect coordination between retailer, supplier and supply chain is obtained, and a VMI contract model considering risk aversion is obtained. The contract The relationship between risk aversion (βs, βr), unit cost of ownership ratio (C), unit income share (r) and unit residual compensation ratio (λ) in the model is the correlation.
