This study combines the use of multi-objective decision trees (MODT) and a fuzzy TOPSIS approach to cope with sequential decision-making under uncertainty with multiple conflicting objectives. To this aim, the MODT generates a Pareto-optimal frontier of solutions for competing objectives, while fuzzy TOPSIS helps assess the noninferior solutions and assign weights to the objectives by considering possible uncertainties in outcomes as well as potential linguistic expression. The proposed approach is illustrated with a temporal decision problem concerning climate-driven refugee resettlement, taking into consideration the challenges of global warming and system interdependencies in an uncertain context. The fuzzy TOPSIS approach was illustrated using two different procedures, and the procedure based on vector normalisation graphically depicts the fuzzy triangular representation of the final ranking.

模糊 TOPSIS 多目标决策树：在难民安置规划中的应用

本研究结合使用多目标决策树（MODT）和模糊 TOPSIS 方法来应对多个相互冲突目标的不确定性下的顺序决策。为此，MODT 为竞争目标生成帕累托最优解前沿，而模糊 TOPSIS 有助于评估非劣解并通过考虑结果中可能的不确定性以及潜在的语言表达来为目标分配权重。所提出的方法以有关气候驱动的难民重新安置的时间决策问题进行说明，同时考虑到全球变暖和不确定背景下系统相互依赖性的挑战。使用两种不同的程序说明了模糊 TOPSIS 方法，基于向量归一化的程序以图形方式描绘了最终排名的模糊三角形表示。
