摘要
以二层规划的方法建立了模糊需求环境下由多供应商、单制造商和多零售商组成的三级供应链系统的协调决策模型,针对模型约束条件皆以区间形式给出,结合混沌搜索算法求解二层规划的便捷性,以混沌搜索算法求解此模型;最后通过算例论证了此模型的有效性,算例结果表明:作为协调主体的制造商可通过与供应商的'协作研发'、与零售商的'价格折扣'相结合的契约形式协调整个供应链系统各成员的利益,实现利益的Pareto改进.
A three-hierarchy supply chain coordination model under the fuzzy demand environment was set up by means of bi-level programming.The supply chain system consisted of multiple suppliers,one manufacturer and multiple retailers.According to the internal form of the model＇s constraints,Chaos Search algorithm was applied to solve the model and an example was cited to verify the feasibility of the model.The numerical results have shown that the core enterprise manufacturer can coordinate the interests among the supply chain members by applying the strategy of coordination development with its suppliers and price discount with its retailers,thus,realizing the Pareto improvement.And the research can provide a basis for the supply chain decision-makers under the fuzzy demand environment.
