摘要
从顾客需求不确定性出发,在考虑批量折扣的情况下,构建了一个基于成本、延迟交货数量、质量和交货提前期的具有模糊权重的多目标订单分配模型。在求解过程中,用隶属度函数表示决策者对各目标值的满意程度,用梯形模糊数来表示各指标的权重,然后将多目标规划问题转化为求全局满意度最优的单目标规划问题。最后通过一个数值算例说明了模型的求解过程。
In the situation of customers＇ uncertain demand and quality discount,a multi-objective order allocation model of fuzzy weight is developed based on cost,the number of late deliveries,quality and delivery lead time.The membership function stands for each objective value＇s satisfaction degree,and the weight of each criterion is described by trapezoidal fuzzy number.The multi-objective programming problem is transformed into single objective programming.Then optimal solution to global satisfaction is obtained.At the end of the paper,the model is illustrated by a numerical example.
