A　group　decision　making　method　based　on　evidential　reasoning　rule　under　conflicting　interval　belief　structures　was　proposed　to　solve　the　problem　of　interval　belief　structures　combination,　considering　the　conflict　expert　opinions　in　the　group　decision-making　environment.　Firstly,　group　decision-making　problems　were　formed　based　on　the　evaluation　information　of　decision　makers　(or　experts)　on　alternatives.　Expert　evaluation　information　(points　of　view)　was　taken　as　evidence,　and　the　validity　of　evaluation　information　was　checked　and　normalized.　Secondly,　the　expert　weight　vector　was　determined　by　the　support　of　the　evidence,　and　all　the　evaluation　information　was　fused　with　the　evidential　reasoning　rule.　Finally,　the　minimum　and　maximum　regret　value　method　was　used　to　select　the　optimal　scheme.　The　case　analysis　shows　that　the　proposed　method　has　consistent　evidence　fusion　results　in　the　process　of　evidence　combination,　and　the　combination　results　are　reasonable　and　convergent.　In　addition,　the　specificity　of　the　evidence　can　also　be　maintained.　©　2020,　Editorial　Department,　Journal　of　South　China　University　of　Technology.　All　right　reserved.
