A fast QuickSolve mode that makes it much faster to re-solve your model after making changes.A built-in model visualizer that highlights your model’s decision variables, objective and constraints directly on your spreadsheet.OpenSolver is free, open source software.Īs well as providing replacement optimization engines, OpenSolver offers:.No artificial limits on the size of problem you can solve – have as many variables and constraints as your computer memory allows (but be aware that large problems can be slow to solve).

Compatible with your existing Solver models, so there is no need to change your spreadsheets.

OpenSolver offers a range of solvers for use in Excel, including the excellent, Open Source, COIN-OR CBC optimization engine which can quickly solve large Linear and Integer problems.

OpenSolver provides the following features: Recent developments are courtesy of Jack Dunn at MIT. It is developed and maintained by Andrew Mason and students at the Engineering Science department, University of Auckland, NZ. OpenSolver is an Excel VBA add-in that extends Excel’s built-in Solver with more powerful solvers. OpenSolver for Google Sheets see our dedicated OpenSolver for Google Sheets page for more info on the Google Sheets versions of OpenSolver.ĬOIN-OR Cup Winner: We are pleased to announce that OpenSolver is the winner of the 2011 INFORMS COIN-OR Cup sponsored by IBM. OpenSolver is also available for Google Sheets OpenSolver 2.9.4 Beta Release version is now also available for download.

The latest stable version, OpenSolver 2.9.3() is available for download this adds support for using Gurobi 9.0 as a solver. Welcome to OpenSolver, the Open Source linear, integer and non-linear optimizer for Microsoft Excel. We guarantee a connection within 30 seconds and a customized solution within 20 minutes.OpenSolver uses the COIN-OR CBC optimization engine If you want to save hours of research and frustration, try our live Excelchat service! Our Excel Experts are available 24/7 to answer any Excel question you may have. Most of the time, the problem you will need to solve will be more complex than a simple application of a formula or function. Excel Solver offers other sensitivity reports and we can further explore this analysis tool to solve more complicated optimization problems and generate more detailed reports. The value of the Lagrange multiplier is a measure of the sensitivity of the constrained objective to changes in the constrained variables. The sensitivity report shows the names, corresponding cells and final values of the variable cells and constraints.

Output: Sensitivity Report How to interpret a sensitivity report ? This is how a Sensitivity Report is presented:įigure 8. The Sensitivity Report will be generated in another worksheet named Sensitivity Report 1. The optimal solution will then reflect in cells C3 to C5 in our worksheet (Sheet 1 below).

The time it takes for Solver to complete the calculations might vary depending on the complexity of the problem. Sensitivity Report option in Solver Results Tick Keep Solver Solution and under Reports, select Sensitivity.

The Solver Results dialog box will appear.

Enter the following information needed by Solver as shown below:.

The Solver Parameters dialog box will appear. We must first use the Excel Solver Analysis and after we have performed the calculation, we can then generate the sensitivity report.

The available stock for reagent B is only 5 liters.

The volume of the whole mixture must still be equal to 110 liters.

Our goal is to obtain a mixture concentration of 10% by determining the required volume of the reagents, with the concentration of each reagent remaining constant. Which can be interpreted as the sum of volume of the pure chemicals divided by the volume of the whole mixture.įigure 3. The concentration of the mixture is given by the formula Suppose we want to prepare a mixture in a laboratory, using water and two chemical reagents A and B. Solver command button in Data tab Prepare our data Goal Seek can be accessed through the Data tab > Solver buttonįigure 2. Final result: Sensitivity Report Where is Excel Solver? Solver is a What-if-Analysis tool that solves for an optimal value in the target cell by changing the values in the variable cells.įigure 1.

Solver, like Goal Seek, is very useful in various fields of study and application. Sensitivity reports can be generated after using the Excel Solver add-in.
