This paper introduces post-MORDM, a decision-support framework that augments Many Objective Robust Decision Making (MORDM). MORDM often creates an intractable number of environmental management policies, characterized by decision variable, objective, and robustness values. This large number of policies inhibits decision support, causing disagreements among decision-makers. Post-MORDM addresses these challenges via the Self-Organizing Map (SOM), synthesizing MORDM data as layers organized in a map-like coordinate system. It uses the SOM to cluster policies, discover salient characteristics, and assess cause-effect relationships between decision-maker choices (i.e. decision variable values) and performance (objective and robustness values). Overall, the goal of post-MORDM is to create a structured platform that encourages negotiation and compromise. We demonstrate post-MORDM with a case study of two illustrative decision-makers for reservoir operation policy in the Colorado River Basin, USA. Post-MORDM helps communicate tradeoffs between storage and delivery objectives, relate tradeoffs to shortage policies, and identify mutually feasible policies.

本文介绍了 post-MORDM，这是一种增强多目标稳健决策 (MORDM) 的决策支持框架。MORDM 通常会创建大量难以处理的环境管理政策，其特点是决策变量、目标和稳健性值。如此多的政策抑制了决策支持，导致决策者之间产生分歧。Post-MORDM 通过自组织地图 (SOM) 解决了这些挑战，将 MORDM 数据合成为在类似地图的坐标系中组织的层。它使用 SOM 对策略进行聚类、发现显着特征并评估决策者选择（即决策变量值）和绩效（目标和稳健性值）之间的因果关系。总体而言，后 MORDM 的目标是创建一个鼓励谈判和妥协的结构化平台。我们通过对美国科罗拉多河流域水库运营政策的两个说明性决策者的案例研究来展示后 MORDM。Post-MORDM 有助于沟通存储和交付目标之间的权衡，将权衡与短缺政策联系起来，并确定相互可行的政策。
