Step 5 в€’ Next, click the Add button to add the three constraints that you have identified. Step 4 в€’ Select range C8:D8 in the By Changing Variable Cells box. Step 2 в€’ In the Set Objective box, select the cell D3. The Solver Parameters dialog box appears. of units sold in Analysis > Solver on the Ribbon.

Note that we have used the Min function to take care to see that the no. of units sold is dependent on the advertising cost per unit and hence is budget for the quarter / Adv. The initial values for advertising budget are set as 10000 per Quarter (Cells вЂ“ C8 and D8). of units available for sale in Quarter1 is 400 and in Quarter2 is 600 (cells вЂ“ C7 and D7). Next, set the cells for the required calculations as given below.ДЄs you can observe, the calculations are done for Quarter1 and Quarter2 that are in consideration are в€’ You can proceed to define the problem as в€’ The number of units sold, indirectly determining the amount of sales revenue.The level of advertising in each quarter affects the following в€’ You are asked to find the amount that can be spent on advertising in the next two quarters subject to a maximum of 20,000. Suppose you are analyzing the profits made by a company that manufactures and sells a certain product. Solver uses the chosen Solving Method to result in the optimal value in the objective cell. The calculation of the value in the objective cell includes the values in the decision variable cells. The values in the decision variable cells are restricted by the values in the constraint cells. Solver evaluation is based on the following в€’ The Solver requires the following parameters в€’ If your target cell, any of your constraints, or both contain references to changing cells that are not of the (changing cell)*(constant) form, you have a nonlinear model. Generalized Reduced Gradient (GRG) Nonlinear This means that each constraint is evaluated by adding together the terms of the (changing cell)*(constant) form and comparing the sums to a constant. The target cell is computed by adding together the terms of the (changing cell)*(constant) form.Д®ach constraint satisfies the linear model requirement. A Solver model is linear under the following conditions в€’ You can choose one of the following three solving methods that Excel Solver supports, based on the type of problem в€’ LP Simplex Now, you should be able to find the Solver command on the Ribbon under the DATA tab. Select Excel Add-Ins in the Manage box and click Go.In case you do not find the Solver command, activate it as follows в€’ The Solver command should appear in the Analysis group as shown below. You can use Solver to find optimal solutions for diverse problems such as в€’Дetermining the monthly product mix for a drug manufacturing unit that maximizes the profitability.Д«efore you proceed with finding solution for a problem with Solver, ensure that the Solver Add-in is activated in Excel as follows в€’ Solver adjusts the values in the decision variable cells to satisfy the limits on constraint cells and produce the result you want for the objective cell. This means that the Solver works with a group of cells called decision variables that are used in computing the formulas in the objective and constraint cells. In Excel, you can use Solver to find an optimal value (maximum or minimum, or a certain value) for a formula in one cell called the objective cell, subject to certain constraints or limits, on the values of other formula cells on the worksheet. Then, one or more other variables are changed repeatedly, subject to the specified constraints, until you discover the best values for the target variables. Instead of setting a specific target value for a variable, the goal is to find the optimum value for one or more target variables, under certain constraints. Solver is a Microsoft Excel add-in program you can use for optimization in what-if analysis.ДЄccording to O'Brien and Marakas, optimization analysis is a more complex extension of goal-seeking analysis.
