A distance‐based group decision‐making methodology for multi‐person multi‐criteria emergency decision support

In this paper, a distance‐based group decision‐making (GDM) methodology is proposed to solve unconventional multi‐person multi‐criteria emergency decision‐making problems. In this model, some decision‐makers are first identified to formulate a group decision‐making framework. Then a standard multi‐criteria decision‐making (MCDM) process is performed on specific decision‐making problems and different decision results are obtained from different decision‐makers. Finally, these different decision results are aggregated into a group consensus to support the final decision‐making. For illustration and verification purposes, a numerical example and a practical unconventional emergency decision case are presented. Experimental results obtained demonstrate that the proposed distance‐based multi‐criteria GDM methodology can improve decision‐making objectivity and emergency management effectiveness.
