【摘要】：为了提高交通应急救援设施选址的科学性与实用性,根据既考虑地点成本,又要保留现有救援点的实际选址需求,提出了基于地点成本的交通救援设施优化选址方法.该方法通过惩罚参数的变动,有选择的保留现有救援点,推出一类条件集合覆盖选址方案;在不改变保留和新建救援点数目的条件下,唯一生成总加权救援时间最小解;考虑救援点建设成本的不同,能够实现建设成本的精确控制,保留的现有救援点是传统方法的2倍,总建设成本和总加权救援时间较传统方法得到多目标优化,实现了经济性与效率性的有效均衡,具有工程应用的可操作性.
[Abstract]:In order to improve the scientificity and practicability of location selection of traffic emergency rescue facilities, according to the need of site selection both in consideration of site cost and in keeping existing rescue sites, a method for optimizing location selection of traffic rescue facilities based on location cost is proposed. By changing the penalty parameters and selectively retaining the existing rescue points, the method proposes a kind of conditional set covering site selection scheme, and generates only the minimum solution of the total weighted rescue time without changing the number of reserved and newly built rescue points. Considering the difference of the construction cost of the rescue site, the construction cost can be controlled accurately, the existing rescue point retained is twice as large as the traditional method, and the total construction cost and the total weighted rescue time can be optimized by multi-objective compared with the traditional method. It realizes the effective balance between economy and efficiency, and has the maneuverability of engineering application.
