摘　　要：为科学准确、高效便捷地评价现代有轨电车路基服役状态,基于云模型的模糊性、随机性及其对定量数据与定性特征转换实现的特点,利用历史监测数据,构建现代有轨电车路基服役状态等级评估体系。同时通过基于指标相关性的指标权重确定(CRITIC)法,更加客观的对各指标赋权,最终生成评价标准云和综合云的对比分析。实验结果表明,该模型具有一定的有效性和合理性,能够对路基服役状态判断提供参考借鉴,并且有利于降低检测过程中仪器成本。In order to evaluate the service status of modern tram roadbed scientifically,accurately,efficiently and conveniently based on the fuzzy and random nature of the cloud model and its characteristics of conversion realization of quantitative data and qualitative features,a modern tram roadbed service status rating evaluation system is constructed using historical monitoring data.Meanwhile,more objective weight is given to each indicator by means of indicator weight determination method based on indicator correlation (CRITIC),and finally a comparative analysis of evaluation standard cloud and comprehensive cloud is generated.The experimental results show that the model has certain validity and rationality,can provide reference for the judgment of roadbed service status,and is conducive to the reduction of instrument cost in the testing process.
