Abstract：

Considering　the　limitation　of　the　existing　studies　and　the　features　of　uncertainty　and　dynamics　of　emergency　event　early-warning　information,　a　dynamic　early-warning　method　for　emergency　event　is　proposed.　Interval　evaluation　grade　standard　is　firstly　described.　Based　on　this　standard　and　the　dynamic　early-warning　interval　information　between　time　points　ti-ti+1,　the　basic　belief　degrees　on　different　assessment　grades　with　regards　to　each　criterion　are　calculated.　Then,　the　basic　belief　degrees　are　transformed　and　integrated　by　evidential　reasoning　from　the　subcriterion　step　by　step　until　the　final　belief　degrees　are　calculated,　which　can　reflect　the　safety　state　of　the　emergency　warning　objects.　Finally,　a　numerical　example　is　provided　to　illustrate　the　feasibility　and　validity　of　the　proposed　method.　©　2017,　Editorial　Office　of　Control　and　Decision.　All　right　reserved.
