Enter the Solver Add-in. This is a handy tool with Excel which, if fed the relevant data, can run the optimisation and remove any of the mathematical heavy-lifting. The ‘Solver’ add-in is shipped with all recent versions of Excel, it’s just not enabled by default. Following the few steps here will ensure the tool is available to you. Linear programming is a mathematical method of optimizing an outcome in a mathematical model using linear equations as constraints. To solve a standard form linear program use Microsoft Excel and the Excel Solver add-in. Excel Solver can be enabled in Excel 2010 by clicking 'file' in the toolbar, 'options,' and 'Add-in.' Check the 'Solver Add-in' option, and click 'OK.' You can access Solver under the 'Data' tab in the toolbar. The most basic linear program to solve is standard form. Define and solve a problem. A list of reports appears in the Reports box of the Solver Results dialog box. If the solving process stopped prematurely when you pressed ESC or selected Stop when a Solving limit was reached, no reports are available. Click to select one or more reports. Select the Outline Reports check box if you would like Solver to use Excel’s outlining feature in the reports. Outlining groups the variables and constraints in the reports into “blocks,” just as you entered them in the Solver Parameters dialog; you can expand or collapse the groups to see only the information you want. Select any other options you want in the Solver Results dialog box, and click OK. The reports you selected appear as new worksheets, inserted into your Excel workbook just to the left of the worksheet containing the Solver model. Reports available when Solver finds a solution In almost all cases where Solver finds an optimal solution, Solver converges to the current solution, or Solver cannot improve the current solution, the Answer Report is available. When the Evolutionary Solving method is used, its Population Report is also available. If Solver finds a (locally or globally) optimal solution, and there are no integer constraints, two additional reports are available: the Sensitivity Report and the Limits Report. Reports available when Solver encounters a problem If you receive the message “The linearity conditions required by this LP Solver are not satisfied,” and the problem has no integer constraints, the Linearity Report is available. This report can help you find cell formulas in your model that make the problem nonlinear (possibly by mistake). If your model is intentionally nonlinear, you should select the GRG Nonlinear Solving method are re-solve the problem. If you receive the message “Solver could not find a feasible solution,” and the problem has no integer constraints, two variants of a diagnostic report, the Feasibility Report and Feasibility-Bounds Report, are available. One of these reports (there’s never a reason to select both of them) can help you find certain constraints that are impossible to satisfy – possibly because you mistakenly used >= instead of. The tutorial explains how to add and where to find Solver in different Excel versions, from 2016 to 2003. Step-by-step examples show how to use Excel Solver to find optimal solutions for linear programming and other kinds of problems. Everyone knows that Microsoft Excel contains a lot of useful functions and powerful tools that can save you hours of calculations. But did you know that it also has a tool that can help you find optimal solutions for decision problems? ![]() In this tutorial, we are going to cover all essential aspects of the Excel Solver add-in and provide a step-by-step guide on how to use it most effectively. • • • • • • What is Excel Solver? Excel Solver belongs to a special set of commands often referred to as What-if Analysis Tools. It is primarily purposed for simulation and optimization of various business and engineering models. The Excel Solver add-in is especially useful for solving linear programming problems, aka linear optimization problems, and therefore is sometimes called a linear programming solver.

While Excel Solver can't crack every possible problem, it is really helpful when dealing with all kinds of optimization problems where you need to make the best decision. For example, it can help you maximize the return of investment, choose the optimal budget for your advertising campaign, make the best work schedule for your employees, minimize the delivery costs, and so on. How to add Solver to Excel The Solver add-in is included with all versions of Microsoft Excel beginning with 2003, but it is not enabled by default. To add Solver to your Excel, perform the following steps: • In Excel 2010, Excel 2013, and Excel 2016, click File > Options. In Excel 2007, click the Microsoft Office button, and then click Excel Options. • In the Excel Options dialog, click Add-Ins on the left sidebar, make sure Excel Add-ins is selected in the Manage box at the bottom of the window, and click Go.
