The　frequent　occurrence　of　natural　disasters　has　drawn　people＇s　attention　to　the　aftermath　work,　especially　the　effective　routing　of　emergency　vehicles　carrying　relief　efforts.　Based　on　the　situation　where　some　disaster　hit　areas　can　be　informed　in　advance　while　could　not　accept　emergency　service,　this　paper　introduces　the　disclosure　date　and　release　date　to　Nomadic　TSP　model,　studies　an　online　Nomadic　TSP　problem　based　on　advanced　information,　and　gives　a　lower　bound.　When　the　metric　space　is　the　real　line,　an　ENO-dd　algorithm　is　presented.　For　general　metric　spaces,　a　GTR-dd　algorithm　is　presented.　Competitive　analysis　is　given　for　these　two　algorithms　respectively.　The　results　indicate　that　the　more　advanced　information,　the　better　these　two　algorithms　perform.　More　general　information　structure　and　optimal　algorithm　design　can　be　the　future　research.
