Research on Optimization of New Retail Terminal Distribution Network Based on Fuzzy Structural Element

新零售模式下,高时效性的物流末端配送对提高顾客满意度具有重要作用,而对末端配送中心位置和数量的确定,是优化末端配送网络的关键。首先,综合考虑影响配送中心位置与数量的模糊因素,构建以配送时间最少、配送中心覆盖范围最大以及系统成本最低为目标的模糊多目标规划模型;其次,采用结构元加权序准则法求解模型,生成三角模糊数简化求解过程;最后,以算例检验方法的有效性。结果表明,所提出的模型能够将模糊因素融入模糊决策过程中,且结构元加权序准则法有助于决策者灵活调整方案和决策,从而对新零售末端配送网络布局进行优化。

Under the new retail model,the time-efficient logistics end distribution plays an important role in improving customer satisfaction.The determination of the location and number of the end distribution center is the key to optimize the end distribution network.Firstly,considering the fuzzy factors that affect the location and quantity of distribution centers,a fuzzy multi-objective programming model is constructed,which aims at minimizing the distribution time,maximizing the coverage of distribution centers and minimizing the system cost.Secondly,the method of structure element weighted order criterion is used to solve the model,and the triangular fuzzy number is generated to simplify the solving process.Finally,an example is given to test the effectiveness of the method.The results show that the proposed model can integrate fuzzy factors into the fuzzy decision-making process,and the method of structure elements weighted order criterion can help decision makers flexibly adjust the scheme and make decisions,so as to optimize the distribution network layout of the new retail end.
