How To Use Solver

Once you click the Solver option, it loads the dialogue box as shown below. Here you specify the parameters to run the solver.

Solver Parameters These parameters will vary depending upon your problem, but lets see what are the most common and mandatory parameters and how they work so that you can utilize the solver in your daily life problems when needed. Followings are the three main parts of the solver which you should understand before applying the solver.

1. Target Cell

The target cell is the cell which will represent the objective or goal. Lets suppose a scenario in which the production manager of a firm would presumably want to maximize the profitability of the Product during each month. The cell that measures profitability would be the target cell.

2. Changing Cells

Changing cells are those cells, that can change or adjust to optimize the target cell. The production manager can adjust the amount produced for each product during a month. The cells in which these amounts are recorded are the changing cells.

3. Constraints

Constraints are restrictions/limitations that you apply on the changing cells. For example in the above scenario, the product manager can’t use more of any available resource (for example, raw material and labor) than the amount of the available resource.

That’s it, specify all of the above mentioned parameters as per your spreadsheet.  Set Objectives represents the target cell, By changing Variable Cells represents the Changing cells and you can add the constraint by hitting the Add button.

Solver Add-in ParametersOnce done with all the configuration, hit the Solve button to run the solver on your Excel spreadsheet.
