基于CVaR准则与ORP-RRP契约的闭环供应链决策模型

摘要

研究了基于预期订货量与实际回收量的回馈与惩罚ORP-RRP契约下的闭环供应链的协调问题.在CVaR准则下,提出了随机需求下单一风险厌恶型的零售商和单一风险中性的制造商组成的闭环供应链模型,探讨了供应链成员的决策行为、风险因子β和废旧品回收敏感性系数τ对废旧品回收价格和最优订货量的影响;研究结果表明:所建立的模型与ORP-RRP契约有效可行,可为供应链管理提供决策参考.%Closed-loop supply chain coordination with risk aversion via ORP-RRP ( orders rebate and pen-alty-recycles rebate and penalty) contracts is investigated. A closed-loop supply chain model composed of a single risk-neutral supplier and a single risk-averse retailer is proposed based on conditional value-at-risk ( CVaR) criterion and demand uncertainty. Decision behaviors of members in closed-loop supply chain are researched, and then the impacts of risk-aversion coefficientβand the sensitivity coefficientτon recycling price and optimal ordering quantities studied. The results show that the established model and the ORP-RRP contracts are effective and feasible, which could provide reference for decision making in supply chain management.
