Hi,

and what does

AH[Ts_, Th_, Tr_, f_, w_, i_] := Module[{
     tipo}, Which[NumericQ[Ts] && NumericQ[Th], tipo = 1,
     NumericQ[Ts] && NumericQ[Tr], tipo = 2,
         NumericQ[Ts] && NumericQ[f], tipo = 3, NumericQ[Ts] &&
        NumericQ[w], tipo = 4, NumericQ[Ts] && NumericQ[i], tipo =
       5, NumericQ[Th] &&
       NumericQ[Tr], tipo = 6, NumericQ[Th] && NumericQ[f], tipo =
        7, NumericQ[Th] &&
       NumericQ[w], tipo = 8, NumericQ[Th] && NumericQ[i], tipo =
        9, NumericQ[Tr] &&
       NumericQ[f], tipo = 10, NumericQ[Tr] && NumericQ[
           w], tipo = 11, NumericQ[Tr] && NumericQ[i], tipo = 12,
         NumericQ[f] && NumericQ[w], tipo = 13, NumericQ[f] &&
       NumericQ[i], tipo = 14, NumericQ[w] && NumericQ[i], tipo = 15];
     tipo
     ]

??
