Group　emergency　decision-making　(GEDM)　problems　have　drawn　great　attention　in　past　few　years　due　to　its　advantages　of　dealing　with　the　emergency　events　(EEs)　effectively.　Due　to　the　fact　that　EEs　are　usually　featured　by　lack　of　information　and　time　pressure,　decision　makers　(DMs)　are　often　bound　rational　and　their　psychological　behaviors　are　very　crucial　to　the　GEDM　process.　However,　DM＇s　psychological　behaviors　are　neglected　in　current　GEDM　approaches.　The　assessments　representing　the　individual　wisdom　provided　by　each　expert　are　usually　aggregated　in　the　GEDM　process.　Nevertheless,　the　aggregation　process　always　implies　summarization　of　data　that　can　result　in　loss　of　information.　To　overcome　these　limitations　pointed　out　previously,　this　paper　proposes　a　new　GEDM　method　that　considers　the　DM＇s　psychological　behaviors　in　the　decision　process　using　prospect　theory　and　replaces　the　aggregation　process　by　a　fusion　method　with　hesitant　fuzzy　set,　which　keeps　the　experts＇　information　as　much　as　possible.　A　case　study　is　provided　to　illustrate　the　validity　and　feasibility　of　the　proposed　method.
