市场供求不确定供应链的多目标鲁棒运作模型

提出了由一个制造商和一个供应商构成的多产品、多阶段供应链在原材料市场的供应和消费市场的需求均不确定条件下的多目标鲁棒运作模型.采用已知概率的离散情景描述消费市场需求和原材料市场供应的不确定性.供应链的运作模型为一个多目标规划问题,满足诸如供应链协调运作、所有供应链成员的目标利润尽可能最大、对应于不确定供求的决策的鲁棒性等多个相互冲突的目标.数值算例的结果表明,将鲁棒性运用于这些目标中,能够减少产品需求和原材料供应的不确定性对目标值的影响.

A Multi-objective Optimization Model for Supply Chain with Uncertain Market Supplies and Demands

A multi-product,multi-stage robust operating model is proposed in this paper to deal with multiple incommensurable goals for a supply chain consisting of a supplier and a producer with uncertain market demands and raw material supplies.The uncertain market demands and raw material supplies are modeled as a number of discrete scenarios with known probabilities.The supply chain operating model is constructed as a multi-objective programming problem to satisfy several conflict objectives,such as coordination of supply chain,the maximum profit of all participants,and robustness of decision to uncertain product demands and raw material supplies.The result of a numerical example proved effectively that the inclusion of robustness measures as part of objectives can significantly reduce the variability of objective values to product demand and raw material supply uncertainties.
