我们针对靠近海岸地区的学校等公共设施的位置提出了多目标决策分析模型，并考虑了海啸淹没的风险。给出了具有三个目标函数的数学规划公式。第一个目标函数是最小值和最大覆盖标准的加权平均值。第二个目标函数表示可能发生海啸事件的风险；为了量化这种风险，应用了 Kaistrenko 和 Pinegina 提出的海啸发生统计模型。第三个标准代表成本。对于多目标优化问题的解决，我们提出了一种基于 NSGA-II 算法的启发式方法，并将其与分解技术进行比较，其中将所考虑的区域划分为更小的子区域，并精确地或启发式地解决每个单独的子区域的问题。这两种方法都在斯里兰卡南部的两个现实生活实例中进行了测试。
We present a model for multi-objective decision analysis with respect to the location of public facilities as schools in areas near to coasts, taking risks of inundation by tsunamis into account. A mathematical programming formulation with three objective functions is given. The first objective function is a weighted mean of a minisum and a maximum coverage criterion. The second objective function expresses risk by possible tsunami events; for quantifying this risk, a statistical model for tsunami occurrences by Kaistrenko and Pinegina is applied. The third criterion represents costs. For the solution of the multi-objective optimization problem, we propose a heuristic approach based on the NSGA-II algorithm and compare it with a decomposition technique where the region under consideration is partitioned into smaller sub-regions, and the problem is solved for each separate subregion either exactly or heuristically. Both approaches are tested on two real-life instances from southern Sri Lanka.
