In the simplest possible terms, a linear model is one in which the variables are not raised to any powers and none of the so-called transcendent functions - such as SIN and COS - are used.
Simplex LP: Use if your worksheet model is linear. In the Solver Parameters dialog box, use the Select a Solving Method list to select one of the following: Limits: Displays the objective cell and its value, as well as the variable cells and their addresses, names, and values.Įxcel Solver can use one of several solving methods. The layout of the Sensitivity report depends on the type of model you’re using. Sensitivity: Attempts to show how sensitive a solution is to changes in the model’s formulas. For the objective cell and variable cells, Solver shows the original and final values. Answer: Displays information about the model’s objective cell, variable cells, and constraints. It works similar to Goal Seek tool in excel. SOLVER is the tool to solve your problem. Things to Remember About Solver in Excel. The tool was developed by Frontline Systems, Inc. To be called a 'solver' doesn't do it justice, though, because it is really a powerful optimization algorithm. The Microsoft Excel solver add-in is one of the features that makes creating engineering and financial models in a spreadsheet a powerful tool. In the Solver Results dialog box, use the Reports list to select each report you want to view: 
You can ask Solver to display one or more reports that give you extra information about the results. If you don’t want to accept the result, select the Restore Original Values option instead.
Select the Keep Solver Solution option. When the optimization is complete, Excel displays the Solver Results dialog box. SOLVER FOR EXCEL ON MAC TRIAL
In any Show Trial Solution dialog box that appears, click Continue to move things along. As Solver works on the problem, you might see the Show Trial Solution dialog boxes show up one or more times. The following image shows the completed Solver Parameters dialog box. In the example, the changing cells are B4 and C4. In the By Changing Variable Cells box, enter the addresses of the cells you want Solver to change while it looks for a solution. Value Of: Enter a number to set the objective cell to that number.įor the example model, Value Of has been selected and 0 entered in the text box. Min: Returns the minimum possible value. Max: Returns the maximum possible value. Note that if you click the cell to enter it, Solver automatically enters an absolute cell address (for example, $B$14 instead of B14). In the Set Objective box, enter the address of your model’s objective cell. With your Solver-ready worksheet model ready to go, here are the steps to follow to find an optimal result for your model using Solver:Įxcel opens the Solver Parameters dialog box. If you choose Keep Solver Solution, Excel permanently changes the worksheet. When Solver finds a solution, you can choose either Keep Solver Solution or Restore Original Values. Finally, you use the By Changing Variable Cells box to specify the cells that Solver can use to plug in values to optimize the result. You use the Set Objective box to specify the objective cell, and you use the To group to tell Excel Solver what you want from the objective cell: the maximum possible value the minimum possible value or a specific value. You set up your Excel Solver model by using the Solver Parameters dialog box.
