基于交互双层模糊规划的敏捷供应链构建与优化

摘要

分析了供应链中不确定性的来源，并用梯形模糊数表达了供应链参数中的不确定性，用梯级平均综合法将模糊数转换为精确数。在分析现有各种合作伙伴决策和供应链构建方法的基础上，提出了基于交互双层模糊规划方法，利用软件 LINGO 13求解该模糊规划，得出最终的精选合作伙伴及最优订货量。该方法兼顾了上下层各自的利益需求，并经过上下层决策者的反复交互协商，最终得到上下层决策者均可接受的妥协优化解。通过一个实例进一步阐述了该方法的决策步骤，并指出了该方法相较于其他方法的优缺点及下一步的研究思路。%The source of uncertainties existing in agile supply chains was analyzed and expressed as trapezoidal fuzzy numbers,which were then defuzzificated with graded mean integration representa-tion.On the basis of analyzing the various methods for selecting partners or configuring agile supply chains,an interactive two-level fuzzy programming was proposed,the solution method of which used the LINGO13 software.Since the method gave consideration to both upper level and lower level inter-ests,an optimal compromise solution could be obtained through repeated negotiation among the deci-sion makers.The decision making procedure was illustrated with an example,and compared with the other methods,and showed the advantages.Something to be desired as well as the further research directions were pointed out.
