摘要
以成本、质量、交货为目标,考虑供应商供应能力、采购数量、供应数量的柔性、评价等级等约束,建立了多产品供应商选择的模糊多目标规划模型。采用降半梯形分布的隶属度函数将模糊多目标规划模型转化为单目标线性规划并求解,应用算例证明了模型的有效性和可行性。
This article formulates a fuzzy multi-objective integer programming model that incorporates three important goals： cost, quality and delivery which subjects to realistic constrains such as vendor＇s capacity, buyer＇s demand, vendor＇s production flexibility, and evaluation grades, etc. Then, the fuzzy multi- objective integer programming model is decomposed into single-objective linear programming model through a semi-down trapezoid membership function. At last, an application example is given to testify the feasibility and effectiveness of the model.
