SolverAdd
I am trying to use the Solver function and have trouble to get the
constraints set up properly. Of the 4 constraints only 2 are used as I can tell by the result as well as by looking at the Solver Parameter window in which only constraints 2 and 4 are listed. Changing for example the sequence didn't help. Version: Excel 2002 SP3, VB 6.3 - Bernd Sub Macro1() ' Reset - Clear all previous settings SolverReset ' Precision 0.1%; Use quadratic extrapolation SolverOptions precision:=0.001, estimates:=1 ' Minimize value for 1st dimentsion SolverOk SetCell:=Range("$M$21"), _ MaxMinVal:=2, _ ByChange:=Range("$B$21:$k$21") ' Constraint 1 - Upper limit for weights SolverAdd cellRef:=Range("$B$21:$k$21"), _ relation:=1, _ formulaText:=1 ' Constraint 2 - Lower limit for weights SolverAdd cellRef:=Range("$B$21:$k$21"), _ relation:=3, _ formulaText:=0 ' Constraint 3 - Sum of all weights equal 100% SolverAdd cellRef:=Range("$a$21"), _ relation:=2, _ formulaText:=1 ' Constraint 4 - Target value for 2nd dimension SolverAdd cellRef:=Range("$L$21"), _ relation:=2, _ formulaText:=Range("$o$21") SolverSolve Userfinish:=True End Sub |
