IIF-ER方法在应急物流设施选址中的应用

Application of interval intuitionistic fuzzy and evidence reasoning in location selection of emergency logistics facilities

为解决不确定性条件下的应急物流设施选址评估的问题,建立基于区间直觉模糊(IIF)与证据推理(ER)的设施选址模型。首先,针对指标评估的不确定性问题,采用区间直觉模糊数(IIFV)表达专家评价信息;然后,考虑到传统IIF在信息集成中存在信息丢失的问题,采用ER集成方法集成评估信息;其次,利用逼近理性解排序法(TOPSIS)对应急物流设施选址方案进行排序;最后,以某城市建立应急物流设施点为例,采用传统IIF信息集成方法与所提方法对比分析,验证模型的有效性。结果表明:所提方法能解决不确定性条件下的应急物流设施选址决策问题,同时也能保证决策质量。

In order to solve the problem of emergency logistics facility location under uncertain conditions,an IIF-ER based model combining was built.For building the model,the interval intuitionistic fuzzy value (IIFV)was used to express the expert evaluation information in view of the uncertainty of index evaluation.Considering thatthe traditional IIF has the problem of information loss in information integration,the method of ER integration was used to integrate the evaluation information.The method of TOPSIS was used to sort the location of emergency logistics facilities.Finally,an example of establishing emergency logistics facilities in a certain city was given to verify the effectiveness of the model.The results show that the model can be used to solve the problem of emergency logistics facility location deeision under uncertain conditions,at the same time,it can ensure the quality of decision-making and shorten the decision time.
