基于COWA-灰色定权聚类的综合管廊PPP项目全生命周期绩效评价

Life cycle performance evaluation of integrated pipeline corridor PPP projects based on COWA-grey fixed weight clustering

综合管廊PPP项目作为改善城市环境、推动城市地下管线高效建设和使用的工程,已在全国范围内得到广泛开展,对综合管廊PPP项目绩效评价的重要性也日益凸显。文中根据霍尔三维结构理论,基于逻辑框架法将城市地下综合管廊PPP项目绩效评价体系划分为4个维度,即投入、活动、产出和影响;构建了涵盖建设前期、建设期、运营维护期及移交期4个阶段的全生命周期绩效评价指标体系;使用COWA算子赋权方法确定评价指标权重,并运用灰色定权聚类法建立系统的绩效评价模型。此外,文中还以广东省中山市某综合管廊PPP项目为对象进行实证分析,从而验证了绩效评价模型的合理性和有效性。以期所提出的绩效评价模型对相关综合管廊PPP项目全生命周期的绩效评价工作具有借鉴价值和意义。

As a project to improve the urban environment and promote the efficient construction and use of urban underground pipelines,integrated pipeline corridor PPP projects have been widely carried out nationwide,and the importance of performance evaluation of integrated pipeline corridor PPP projects has become increasingly prominent.Based on Hall's three-dimensional structure theory,this paper divides the performance evaluation system of urban underground integrated pipeline corridor into four dimensions,namely input,activity,output and influence.The whole life cycle performance evaluation index system covering four stages:pre-construction period,construction period,operation and maintenance period and transfer period is established.The evaluation index weights are determined by COWA operator weighting method,and the performance evaluation model is established by grey fixed weight clustering method.In addition,this paper also carries out empirical analysis on a comprehensive pipeline corridor PPP project in Zhongshan City,Guangdong Province,so as to verify the rationality and effectiveness of the performance evaluation model.The proposed performance evaluation model is expected to have reference value and significance for the performance evaluation of the whole life cycle of relevant integrated pipeline corridor PPP projects.
