Putting the command UserFinish:=True/False after SolverSolve has no effect.īefore you ask, I have activated the solver add-in in my excel workbook and referenced it in my VB editor. C30) and which cell is to be changed (ie. However, the cell references for which cell is the target cell (i.e. Tool/solver for resolving differential equations (eg resolution for first degree or second degree). F7=L7, F7 >=0, and C27=60000) and the type of solve (ie max, min or equal to value) is already selected. The algorithm is implemented using Microsoft Excel. Incidentally, when I open the solver window to run it manually, the three constraints set up in the macro are already entered (ie. Excel Solver is a fantastic tool, but most examples only cover simple marketing use cases. When its done finding a solution, some of the numbers are actually 0.9999996, 1.0000000003, 0.0000017, and so on. Im trying to use solver to solve a non-linear problem, but the results are not consistent and change under certain conditions. The only problem is that Solver is not really treating the cells constrained as binary properly. SolverAdd CellRef:="$C$27", Relation:=2, FormulaText:=60000 I created a model in Excel to use in conjunction with Solver. SolverAdd CellRef:="$F$7", Relation:=3, FormulaText:=0 Can anyone tell me why my macro doesn't work? Solving a linear program in Excel requires five main steps.
When I run the solver manually however, it works fine. If the Data tab does not have the choice Solver available, then look at the Office Button. When I run the macro however, nothing happens whatsoever to the values in the cells. In the Add-Ins dialog box that opens, check the box next to Solver and click OK. There are no fixed limits on iterations or subproblems, but the backend server currently limits solving time to 30 seconds.
Make sure Excel Add-ins is selected and click Go. Problem size limits in the Solver Add-on are the same as in the Excel Solver (200 decision variables and 100 constraints in addition to bounds on the variables). Hi, I am writing a macro to automatically set up and run the solver add in for excel (I am using excel 2000). Choose the Add-ins section on the left, and go down to the Manage: drop-down menu.
