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...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。展开更多

The planning of dty fife stations is an important safeguard to improve the city fire security. Whetiief the planning is scientific and rational will affect the fire security of the entire dty directly. In this papei; road networks were built based on GIS, the service range of fire stations was calculated based on time cost, and the planning of fire stations in main districts of Hangzhou was evaluated in terms of security, efficiency,and balance The results showed that this planning made significant improvements in security and balance of fke fighting service provided by the main districts of Hangzhou, but few improvements were high in efficiency. On. tiie whole, Xiacheng District did the best job in fire control, and Xihu District was expected to make efforts to improve its fire security.展开更多
