With　respect　to　the　features　of　dynamicality　and　uncertainty　of　emergency　events,　a　prospect-theory-based　method　for　dynamic　adjustment　of　emergency　alternatives　is　proposed.　The　problems　of　emergency　event　are　firstly　described,　and　the　problems　needed　to　be　solved　are　presented.　And,　the　method　and　processes　for　dynamic　adjustment　of　emergency　alternatives　are　elaborated,　according　to　the　idea　of　value　function　and　weighting　function　of　prospect　theory.　Finally,　a　numerical　example　is　provided　to　illustrate　the　feasibility　and　effectiveness　of　the　proposed　method.　©　2016,　Editorial　Office　of　Control　and　Decision.　All　right　reserved.
