  Level/1..3/: P, z, Goal;
  Variable/1..2/: x;
  H_Con_Num/1..1/: b;
  S_Con_Num/1..4/: g, dplus, dminus;
  H_Cons(H_Con_Num, Variable): A;
  S_Cons(S_Con_Num, Variable): C;
  Obj(Level, S_Con_Num): Wplus, Wminus;
endsets
data:
  P= ? ? ?;
  Goal = ? ? 0;
  b = 12;
  g=  1500 0 16 15;
  A =  2  2;
  C =  200  300  2 -1  4  0  0  5;
  Wplus =  0 0 0 0

  Wminus = 1 0 0 0

         0 0 3 0;
enddata

min=@sum(Level: P * z);
@for(Level(i):
z(i)=@sum(S_Con_Num(j): Wplus(i,j)*dplus(j))
   +@sum(S_Con_Num(j): Wminus(i,j)*dminus(j)));
@for(H_Con_Num(i):
@sum(Variable(j): A(i,j) * x(j)) <= b(i));
@for(S_Con_Num(i):
@sum(Variable(j): C(i,j)*x(j))
   + dminus(i) - dplus(i) = g(i);
);
@for(Level(i) | i #lt# @size(Level):
@bnd(0, z(i), Goal(i));
);
参考资料给出：P1=1，p2=0，p3=0，goal1，goal2取较大数，试了几个后，出现如下错误，求解？THE MODEL IS POORLY SCALED AND MAY YIELD ERRATIC RESULTS.  THE UNITS OF THE ROWS AND VARIABLES SHOULD BE RESCALED SO THE COEFFICIENTS COVER A MUCH SMALLER RANGE.
