Note The Solver add-in is not enabled by default. Before you can use this function, the Solver add-in must be enabled and installed. After the Solver add-in is installed, you must establish a reference to the Solver add-in. CellRef Required Variant. A reference to a cell or a range of cells that forms the left side of a constraint.
Relation Required Integer. The arithmetic relationship between the left and right sides of the constraint. If you choose 4 or 5, CellRef must refer to adjustable changing cells, and FormulaText should not be specified. FormulaText Optional Variant. The right side of the constraint.
If CellRef and Relation do not match an existing constraint, you must use the SolverDelete and SolverAdd functions to change the constraint. This example loads the previously calculated Solver model stored on Sheet1, changes one of the constraints, and then solves the model again.

I need to run Solver multiple times in succession, so I put the Solver code in a Visual Basic script's loop. The problem is, when each iteration of Solver gets run, I have to respond to the pop-up window which asks me if I want to keep the solver solution or revert back to the original values. I've tried implementing "Application. Any suggestions? This thread is locked.

MaxMinVal is an optional variant that tells the solver function how you would like the equation solved, in our case we want to solve for a specific value ValueOf is the specific value we want to solve for 50in our case must be specified because our MaxMinVal variant requires a value.

Follow the below steps to enable it. SetCell: This will be the cell reference that needs to be changed i.
CellRef: To set the criteria to solve the problem, what is the cell needs to be changed. Relation: In this, if the logical values are satisfied then we can use the below numbers. To arrive at this number we have certain conditions. Based on these conditions we need to identify how many units to sell at what price to get the profit value of Step 1: Start the VBA subprocedure.
Step 2: First we need to set the Objective cell reference by using the SolverOk function. B8 cell. Step 4: Now we need to set this cell value toso for MaxMinVal use 3 as the argument value.
The next argument is ByChange i. B2 cell. Step First cell i. Units to Sell must be an Integer value for this also set up the criteria as below.

Re: Using Solver in a Loop As you have changed the layout a bit and you also have blank rows in your data range I've changed the macro a bit but as far as I could see this worked. Don't forget to set a reference to solver in the "Visual Basic" window, see post 2. This worked perfectly. Now I am also interested in running this macro again on the same rows but shifting the columns over.
Can i just change the column locations listed on the macro to the new ones? I am interested in doing this at three different column set locations. So would I run three macros? Is that possible? Re: Using Solver in a Loop Thank you for your help. I will mark it as solved now. I am now going to really look at that macro and learn the coding!

Basically it starts in one cell, runs solver, moves the target and constraint cells to the right one, solves, moves target and contraint cells to the right 14, solves, right one, solves, right 14 solves, until it finds a blank. Replace "A2" with the column you are wanting to find the number for. The first part looks different then the others, so I did not include it in the "loop", but it would be easy enough to add, if the differences were due to a typo.

My question is how to do the cell movement, I have tried to loop that and cannot get it working properly. The code works when written out the long way, but not when I have attempted a loop. Active Oldest Votes.
Untested but perhaps something like I was working on something really similar but yours is cleaner. You should share that is the column number, or input a conversion so OP can just input the starting range and the column is gathered from that.
