We can either choose to accept the solution or restore the original values. We then click Ok.ġ0) The parameters are shown below, we then click Solve.ġ1) The Solver Results dialog box should pop up stating that Solver has found a solution. So we set cell $E$9 <= 14000 ml as shown. So we set cell $D$9 = 4700.ĩ) The last constraint we have to set is to ensure that the total volume of all three products does not exceed 14000 ml. We click Add to set this constraint.Ĩ) The next constraint we need to set is to ensure that 4700 ml of the starch solution is ordered in order to fulfill an existing order quota. Read More: Optimizing an investment portfolio using Excel SolverĦ) The first constraint we are going to add is to ensure that the mixture of liquid biopesticide does not exceed 4000 ml. For solving the method make sure Simplex LP is selected as shown below.ĥ) We are now going to add constraints based on the limitations or criteria the farmer has. This is the range we want Solver to adjust, in order to meet our target. We select the range $B$9:$D$9 as our Changing Variable Cells. This makes sense from a logical perspective since we would like to obtain the maximum insect egg cell death, possible.

The overall combination of the three mixtures must not exceed 14000 ml daily.ģ) Firstly, we go to the Data tab > Analysis group > Solver as shown below.Ĥ) For our Solver Parameters, we set the objective cell as $E$13 and we choose to the max.The starch solution mixture must be equal to 4700 ml to fulfill an existing order.The mixture of neem oil and garlic must be at least 5500 ml.The mixture of liquid biopesticide cannot exceed 4000 ml.In other words, E9 contains the formula =SUM(B9: D9). The value in cell E9 is the sum of all the products used on the farm. The total maximum amount of achievable insect egg death is calculated in E13, using the formula =SUM(B10: D10). This formula calculates the estimated death of eggs, based on the level of effectiveness of the starch solution. This formula calculates the estimated death of eggs based on the level of effectiveness of the mixture of neem oil and garlic.

This formula calculates the estimated death of eggs, based on the level of effectiveness of the mixture of liquid biopesticide. The cell range B10: D10 denotes the death of eggs per unit of product. The source data for performing solver is given below.ġ) The variable cells, Solver is going to adjust in order to meet the target is the range B9: D9. Also, the overall addition of the three mixtures working in tandem, cannot exceed 14000 ml.

In addition, 4700 ml of the starch solution must be ordered to fulfill an existing order quota. For the mixture of neem solution at least 5500 ml of the product must be ordered. The amounts of liquid biopesticide cannot exceed 4000 ml. Let`s work on an example where we are going to use the solver to determine the maximum reduction in insect growth and viability that can be achieved. Use of Excel Solver for Solving Linear Programming Problems

After this, you will see the Solver option is attached to your Excel Data option on the Analyze.

In the Add-Ins dialogue box select the Solver Add-in and press OK.

In the Excel Options dialogue box press on to the Add-Ins and there, on to the Manage option select the Excel Add-Ins and press Go.

Click on the File option on top and then press on to the.

The procedure for enabling it is given below. Although the Solver Add-Ins option is available for all the versions of Excel beginning from 2003, by default it is not enabled.
