摘要
研究了在决策者不同风险态度下的由供应商、分销商和零售商组成三层供应链集成优化问题。考虑供应链中价格、质量、交货、需求和供应的不确定风险因素为模糊变量,应用可信性理论建立了模糊机会约束规划模型,可信性测度的置信水平代表了决策者的风险偏好程度。使用模糊变量的乐观值和悲观值将机会约束转化为清晰的等价形式。最后,通过数值算例分析了决策者的风险态度的变化对集成供应链的影响。
This paper researches integrated optimization problem of three-level supply chain consisting of suppliers,distributor and retailers under decision makers＇ different risk attitude.Considering risk factors for price,quality,delivery,demand and supply as fuzzy variables,we model fuzzy chance constrained programming credibility theory.Confidence level of credibility measure represents the degree of decision makers＇ risk preference.The optimistic value and the pessimistic value of fuzzy variables are used to convert chance constrained into crisp equivalents.Finally,a numerical example is given to analyze the impact of decision makers＇ risk attitude toward integrated supply chain.
