The contents of the cell must be equal to a fixed amount. Solver allows you to use one of these six constraints: Press the Add button and the constrait according to the image.ĭon't worry about the ''$'' sign. We must determine the upper and lower limit for this cell. To accelerate the process, all the constraints have been added except those related to the B3 cell. Without constraints for each variable you select, the Solver will give a solution moving toward infinity.Constraints force the solver to consider the limits of your variable cells. Select the other cells while still holding the CTRL key. Select the first cell you wish to have in the box. To select many cells, use the procedure below. The B21 cell B21 are variable (growth rate) and B3, B4 and B5 (sales the first month). The By changing variable cells box is where you select the cells that you allow the Solver to change to optimize the objective.Please note that changing cells must always be cells with only numbers, not formulas. You can either maximize, minimize or determine a goal value to attain. For this example, it's the D19 cell that contains the sum profit for the quarter.Afterward, you determine what you want to achieve. The Set Objective box is where you place the cell you want to optimize. With these informations, use the Solver to find the optimal solution. The sales for Product 300 (B5) must be between 5 000$ and 75 000$. The sales for Product 200 (B4) must be between 10 000$ and 125 000$. The sales for Product 100 (B3) must be between 45 000$ and 250 000$. The monthly growth rate of the company (B21) must be between 15% and 150%. But it also has some constraints that it must adhere. The company wants to optimize its quarterly profits. Follow the instructions below to activate Solver or any other add-ins you wish.įrom the left column, select the Add-Ins category.įrom the Manage area, select Excel Add-ins and press the Go button.įrom the list of Add-ins, select Solver Add-in.Īt the end of the Data tab you will now find the Solver tool. Activate the SolverĪdd-ins are usualy not activated when you use Excel. In this case, all the revenus and charges depend on the growth rate located in cell B21. Here are two views of the same worksheet: with the values or showing the formulas. Otherwise, your résultat ira vers l'infini ! Otherwise, your result will go toward infinity! (And beyond if you believe Buzz Lightyear) Before we startįor this exercise, you can use the file excel2007-2010-exercises.xlsx on the demonstrations files web page. Don't forget to add theĬonstraints to your model. Maximize your profits, minimize your losses or achieve a goal with the leastĪmount of resources.

Those pieces of software are called add-ins. Many companies have added options to Excel to make it even better. Microsoft Excel is known to be one most used application in the world because it's so versatile.
