Start the macro recorder (Tools > Macro > Record New Macro. Let's use the problem from Example 2 above. Is to first record all the steps used to set up and run the solver. Macro that can be run by pressing a single button. Routine a number of times using the same model, it is convenient to create a If you need to solve the same system of equations or run an optimization For optimization problems, this means that the solution may be only a local optimum. The solution may depend upon the starting values. This example has demonstrated a very important point having to do with the Excel solver and optimization in general.

Download the Excel file, enter the solver parameters (previous 7 steps) and find the optimal solution.Figure 4: Mechanism showing two possible configurations. 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. In File, select options followed by add-ins. In an Excel workbook, press Alt+F11 to open the Visual Basic Editor. On the Data tab, in the Analyze group, click Solver.Įnter the solver parameters (read on). The steps to add an add-in to the Excel toolbar are listed as follows: a. 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.
