摘要
为了合理布局应急值守点,实现城镇燃气管网突发事件高效处置,提出以应急抢险总到达时长最短、值守点与突发事件热点区域距离最近、应急值守点数量最少为优化目标,建立城镇燃气管网应急值守点选址多目标优化模型.采用基于拥挤距离的多目标粒子群算法求解模型,基于应急抢险时效性原则和合理性原则,建立备选值守点适应性评价指标体系,结合层次分析法(AHP)和逼近理想解排序法(TOPSIS),开展应急值守点选址方案适应性评价.研究结果表明:提出的城镇燃气管网应急值守点选址方法满足应急处置时效性、经济性与各值守点承担工作量均衡性,能确保筛选出的值守点具有良好的应急抢险适应性,实现值守点数量规模与布局结构优化.研究结果可为城镇燃气管网应急值守点布局优化提供参考.
Abstract
In order to reasonably arrange the layout of emergency guard stations and achieve the high-efficient emergency dis-posal of urban gas pipeline network,a multi-objective optimization model for the site selection of emergency guard stations for urban gas pipeline network was developed,with the optimization objectives of the shortest total arrival time of emergency res-cue,the shortest distance from the guard station to the hot-point area of emergency,and the minimum quantity of emergency guard stations.The multi-objective particle swarm algorithm based on the crowding distance was utilized to solve the model.Based on the principle of timeliness and rationality of emergency rescue,an index system was established to evaluate the adaptability of candidate guard stations.The adaptability evaluation on the site selection scheme of emergency guard stations was carried out by combining the methods of analytical hierarchy process(AHP)and the technique for order preference by similarity to an ideal solution(TOPSIS).The results show that the proposed method for the site selection of emergency guard stations for urban gas pipeline network not only satisfies the timeliness and economy of emergency disposal and the balance of workload of each guard station,but also ensures that the selected guard stations have good adaptability to emergency rescue,so as to realize the optimization of the quantity and layout of guard stations.The research results can provide reference for the layout optimization of emergency guard stations for urban gas pipeline network.
