突发性自然灾害经常对大型工程的建筑与生产设施造成重大损失,而受损设施的维修和重建过程常出现物资供给不足、物资供给效率低以及物资分配公平性等问题.本文以某大型光伏电站为依托,从应急物资节点选址影响因素入手,建立受突发性灾害作用后的应急物资节点选址评价指标系统,采用AHP-CRITIC(analyt-ic hierarchy process-criteria importance through intercriteria correlation)组合赋权法实现应急物资存放点选址评价结果的计算.同时,基于研究区内部路网开展大型光伏场地路口至多物资存储节点的最优路径研究,并采用GIS(geographic information system)技术求解出最短运输路径.结果表明:该大型光伏场地应急物资节点选址评价结果等级为"好"与"较好"的区域主要分布在研究区北部,占总面积的33.38%;基于最短运输路径原则通过综合对比线路总长与重复路线占比,由入口3出发至各应急物资节点的路径为最优路线.研究成果可为类似大型工程的安全运营和应急管理提供技术支持和参考.
Emergency Material Node Siting and Optimal Route Selection for Large Photovoltaic Power Plants Based on AHP-CRITIC and GIS
Sudden natural disasters often result in significant losses to the construction and production facilities of large-scale projects.In the repair and reconstruction process of damaged facilities,problems such as insufficient supply of materials,inefficient material distribution,and fairness issues are commonly encountered.A system of evaluation indexes for the siting of emergency material nodes after being affected by sudden-onset disasters has been established,relying on a large photovoltaic power station.The calculation of the evaluation results of the siting of the emergency material storage points has been accomplished by adopting the AHP-CRITIC(analytic hierarchy process-criteria importance through intercriteria correlation)combined weighting method.Simultaneously,an optimal path study from the intersection of large photovoltaic power plants to multiple material storage nodes has been conducted based on the internal road network of the study area.The shortest transportation path has been solved using GIS(geographic information system).The results reveal that the areas with"good"and"better"siting evaluation results for emergency material nodes of large photovoltaic power plants are predominantly distributed in the northern part of the study area,accounting for 33.38%of the total area.The best route from entrance 3 to each node of emergency supplies has been determined by comparing the total length of the route and the proportion of duplicated routes based on the principle of the shortest transportation route.The research results can provide technical support and reference for the safe operation and emergency management of similar large-scale projects.
