DEAHP　as　a　weight　derivation　procedure　for　analytic　hierarchy　process　(AHP)　has　been　found　suffering　from　some　significant　drawbacks.　Recently,　Mirhedayatian　and　Saen　(2011)　[5]　proposed　a　new　procedure　entitled　Revised　DEAHP　for　AHP　weight　derivation　[S.M.Mirhedayatian,　R.F.Saen,　A　new　approach　for　weight　derivation　using　data　envelopment　analysis　in　the　analytic　hierarchy　process,　Journal　of　the　Operational　Research　Society　62　(2011)　1585-1595].　This　paper　provides　a　detailed　note　to　reveal　that　(1)　the　Revised　DEAHP　cannot　derive　true　weights　from　perfectly　consistent　pairwise　comparison　matrices,　(2)　it　may　produce　irrational　weights　for　inconsistent　pairwise　comparison　matrices,　(3)　it　still　suffers　from　rank　reversal　problem　when　an　efficient　decision　criterion　or　alternative　is　added　or　removed,　(4)　the　use　of　the　super-efficiency　model　in　data　envelopment　analysis　(DEA)　for　AHP　weight　derivation　is　redundant　and　meaningless　when　there　exist　multiple　decision　criteria　or　alternatives　that　are　efficient　in　a　pairwise　comparison　matrix,　and　(5)　it　may　produce　a　completely　reversed　ranking　that　is　totally　opposite　to　the　rank　obtained　by　the　eigenvector　method　in　the　case　of　hierarchical　structures,　leading　to　a　wrong　decision　being　made.　©　2011　Elsevier　Ltd.
