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.

Download the Excel file, enter the solver parameters (previous 7 steps) and find the optimal solution.Microsoft Excel is known to be one most used application in the world because it's so versatile. This solution uses all the resources available. This solution gives the maximum profit of 25600. Check 'Make Unconstrained Variables Non-Negative' and select 'Simplex LP'.Ĭonclusion: it is optimal to order 94 bicycles and 54 mopeds. Click Add to enter the following constraint.Ħ. Enter OrderSize for the Changing Variable Cells.ĥ. You have the choice of typing the range names or clicking on the cells in the spreadsheet.Ĥ. The result should be consistent with the picture below. On the Data tab, in the Analyze group, click Solver.Įnter the solver parameters (read on). To find the optimal solution, execute the following steps.ġ. We shall describe next how the Excel Solver can be used to quickly find the optimal solution.

It is not necessary to use trial and error. This solution has a total profit of 19000. With this formulation, it becomes easy to analyze any trial solution.įor example, if we order 20 bicycles, 40 mopeds and 100 child seats, the total amount of resources used does not exceed the amount of resources available. Total Profit equals the sumproduct of UnitProfit and OrderSize. The amount of storage used equals the sumproduct of the range C8:E8 and OrderSize. Insert the following three SUMPRODUCT functions.Įxplanation: The amount of capital used equals the sumproduct of the range C7:E7 and OrderSize. To make the model easier to understand, create the following named ranges. What is the overall measure of performance for these decisions? The overall measure of performance is the total profit of the three products, so the objective is to maximize this quantity.Ģ. For example, each bicycle uses 300 units of capital and 0.5 unit of storage.Ĭ. What are the constraints on these decisions? The constrains here are that the amount of capital and storage used by the products cannot exceed the limited amount of capital and storage (resources) available. What are the decisions to be made? For this problem, we need Excel to find out how much to order of each product (bicycles, mopeds and child seats).ī. To formulate this linear programming model, answer the following three questions.Ī. The model we are going to solve looks as follows in Excel.ġ. You can find the Solver on the Data tab, in the Analyze group. Under Add-ins, select Solver Add-in and click on the Go button.Ĥ.
