摘　　要：为有效评估城市配水工程的质量,并充分考虑到评估过程中的影响因子模糊性和随机性,提高配水工程对城市供水系统的稳定性和可靠性,全面反映配水工程实际质量状况,提出了一种基于组合赋权法和云模型的城市配水工程质量评价模型。通过构建包含水质状况、人员因素、施工质量、政府监管、设备材料5个一级指标及32个二级指标的评价体系,并进一步划分为不同的评价指标质量等级。同时,为了确保权重分配的科学性和合理性,运用拉格朗日乘子法将最优最劣法(Best-worst Method,BWM)和改进的Critic法得到的权重进行最优化组合。并基于云模型理论最终确定了各质量等级的评价参数,并应用于杭州市第二水源千岛湖配水工程进行进行质量安全评价,通过计算云相似度来确定最终工程质量等级,并与模糊综合评价法对比验证。研究结果表明,基于构建的模型能够准确反映实际城市配水工程的质量状况。最终该工程当前的质量等级为优秀(Ⅱ级),与实际工程评估结果相符,主要影响因素为培训效果(X2,4)、团队协作能力(X2,6)及设备校准与检验(X5,4)。此外,将该模型的评价结果与传统的模糊综合评价法对比结果发现,所建模型在解决指标的关联性、模糊性和随机性问题上具有显著优势,提高了城市配水工程质量评价结果的稳定性和可信度。To effectively evaluate the quality of urban water distribution projects and fully consider the fuzziness and randomness of influencing factors in the evaluation process,thereby improving the stability and reliability of water distribution projects in urban water supply systems and comprehensively reflecting the actual quality status of these projects,this paper proposes a quality evaluation model for urban water distribution projects based on a combination weighting method and cloud model.The evaluation system is constructed,including five primary indicators:water quality condition,personnel factors,construction quality,government supervision,and equipment and materials,as well as 32 secondary indicators,further divided into different quality levels for each evaluation indicator.To ensure the scientific and rational weight distribution,the Lagrange multiplier method is used to optimize the combination of weights obtained from the Best-Worst Method(BWM)and the improved Criteria lmportance Though Intercrieria Correlation(Critic)method.Based on the cloud model theory,the evaluation parameters of each quality level are finally determined and applied to the quality and safety evaluation of the Qiandao Lake Water Diversion Project,the second water source of Hangzhou.The final project quality level is determined by calculating the cloud similarity,and the results are compared with those obtained using the fuzzy comprehensive evaluation method.The research results show that the constructed model can accurately reflect the actual quality status of the urban water distribution projects.The final quality level of the project is excellent(Level II),consistent with the actual project evaluation results,with the main influencing factors being training effectiveness(X2,4),team collaboration ability(X2,6),and equipment calibration and inspection(X5,4).Moreover,a comparison of the evaluation results with those of the traditional fuzzy comprehensive evaluation method reveals that the established model has significant advantages i
