基于后悔理论的动态三角模糊数在冷链配送中心选址中的应用

Application of Dynamic Triangular Fuzzy Number Based onRegret Theory in Cold Chain Distribution Center Location

为了提高冷链配送中心选址的精确性和合理性,该研究构建了一种基于后悔理论的动态三角模糊数多属性决策方法。该方法应用在广西南宁市某公司冷链配送中心选址的研究上。通过整理文献、实地考察以及咨询专家等方法,建立了以运营成本、交通运输情况、人力资源情况和经济环境等4个指标为主的评价指标体系;考虑到不同时间段各指标数值的差异性,引入动态三角模糊数,同时,为了避免在决策中决策者产生负面情绪,并考虑冷链配送中心本身的增长性,采用了后悔理论的方法;通过实例验证了本研究构建方法的可行性。

In order to improve the accuracy and rationality of cold chain distribution center location,this paper constructs a dynamic triangular fuzzy number multi-attribute decision making method based on regret theory,and applies it to the case of cold chain distribution center location of a company in Nanning,Guangxi.Firstly,by sorting out the literature,on the spot investigation and consulting experts,an evaluation index system based on four indicators of operation cost,transportation situation,human resources situation and economic environment is established.Secondly,considering the difference of each index value in different time periods,this paper introduces dynamic triangular fuzzy number.At the same time,in order to avoid negative emotions of decision makers in decisionmaking,and considering the growth of cold chain distribution center itself,the method of regret theory is adopted.Finally,the feasibility of the method is verified by an example.
