Urgent　and　critical　situations　or　so-called　emergency　events,　such　as　terrorist　attacks　and　natural　disasters,　often　require　crucial　decisions.　When　an　emergency　event　occurs,　emergency　decision　making　plays　an　important　role　in　dealing　with　it,　and　hence,　its　importance　nowadays　is　increasing.　In　the　real　world,　it　is　difficult　for　only　one　decision　maker　to　take　a　comprehensive　decision　for　coping　with　an　emergency　event.　Consequently,　many　practical　emergency　problems　are　often　characterized　by　a　group　emergency　decision　making　(GEDM)　scheme.　Different　studies　show　that　human　beings　are　usually　bounded　rational　under　risk　and　uncertainty,　and　their　psychological　behavior　is　very　important　in　the　decision-making　process.　However,　such　behavior　is　neglected　in　current　GEDM　studies.　Therefore,　this　study　proposes　a　novel　GEDM　method　that　considers　experts＇　psychological　behavior　in　the　GEDM　process.　The　method　is　then　applied　to　a　case　study　and　compared　with　other　related　approaches.　Finally,　discussions　are　presented　to　illustrate　the　novelty,　feasibility,　and　validity　of　the　proposed　GEDM　method,　showing　the　importance　of　experts＇　psychological　behavior　in　GEDM.　(C)　2017　Elsevier　Inc.　All　rights　reserved.
