云模型和证据推理决策下智慧水务建设绩效评价

Performance Evaluation of Smart Water Construction Based on Cloud Model and ER

考虑到智慧水务建设绩效评价过程中信息的不确定性和传统处理云模型评价信息方法会造成不确定信息损失的问题,提出云模型结合证据推理(evidence reasoning,ER)的多属性决策方法。首先,通过采用X条件云生成器获取评价信息。然后,考虑专家评价信息之间存在冲突,采用改进ER方法对其修正并集成评价信息,得到专家对智慧水务建设绩效评价的结果。案例分析结果表明,所提方法能有效解决信息的不确定性以及评价过程中不确定信息损失的问题,为智慧水务建设绩效评价提供了新的技术途径。

Considering the uncertainties in the process of performance evaluation and the loss of uncertain information caused by traditional cloud model evaluation methods,a smart water construction performance evaluation method based on cloud model and improved evidential reasoning is proposed.Firstly,the evaluation information is obtained by using X conditional cloud generator.Then,considering the conflict between expert evaluation information,the improved ER method is used to revise and integrate the evaluation information,and the results of expert performance evaluation for green suppliers are obtained.The results of case study show that the proposed method can effectively solve the uncertainty of evaluation information and the loss of uncertain information in the evaluation process.The applicability of the algorithm is verified,which provides a new technical way for the performance evaluation of smart water construction.
