由于磁浮系统安全风险评估指标内容不够全面、指标赋权方法单一、评估结果缺乏科学合理分档排序等问题，导致评估结果准确性不足，难以有效改善磁浮系统的安全水平。结合信度检验和因子分析法效度检验，从应急响应、环境、基础设施、列车行驶、人员5个方面构建全面有效多层次的评估指标内容。通过模糊层次分析法(Fuzzy Analytic Hierarchy Process, FAHP)、优序图法以及CRITIC(Criteria Importance Through Intercriteria Correlation)法进行组合赋权计算指标权重，改善指标权重单一偏向性问题，从而提升评估结果准确性。基于组合赋权加权秩和比法(Weighted Rank Sum Ratio, WRSR)的磁浮系统安全评估模型，对评估结果科学合理地分档排序，以热力图的方式将评估结果可视化。以江西兴国“红轨”磁浮线和上海磁浮示范线为例，评估结果均为中低风险，通过欧式距离法检验评估结果一致性，验证评估方法的有效性和合理性；通过与传统评估模型对比，验证评估方法的创新性。结果表明，所提评估模型能够准确反映磁浮系统的安全风险程度，为提高磁浮系统安全水平提供了一定参考。
Abstract：To address the deficiencies in current safety risk assessment models for maglev systems, including incomplete evaluation indicators, oversimplified weight assignment methods, and unscientific classification of assessment results—issues that compromise accuracy and hinder safety improvement—a comprehensive framwork is proposed. By combining reliability and factor analysis-based validity tests, a multi-level evaluation indicator system is constructed from five dimensions: emergency response, environment, infrastructure, train operation, and personnel. To mitigate the bias of oversimplified weight assignment approaches, a combined weighting method integrating Fuzzy Analytic Hierarchy Process(FAHP), precedence chart method, and Criteria Importance Through Intercriteria Correlation(CRITIC) is developed for objective indicator weighting. Furthermore, a safety assessment model based on the Weighted Rank Sum Ratio(WRSR) method with combined weighting is established to classify and rank risks scientifically, with results visualized via heatmaps. Case studies on the Xingguo ‘Red Rail' maglev line in Jiangxi and the Shanghai maglev demonstration line demonstrate that both systems exhibit medium-low risk levels. The consistency of results is verified using Euclidean distance analysis, while comparisons with traditional models confirm the method's validity, rationality, and innovativeness. The findings indicate that the proposed model can accurately reflect the level of maglev system safety risks and provide useful references for enhancing operational safety of maglev systems.
