5 Ways To Create Solver Answer Report In Excel

Creating a Solver answer report in Excel is a valuable skill for data analysis and decision-making. The Solver add-in is a powerful tool that allows users to find optimal solutions to complex problems by minimizing or maximizing a target cell, subject to certain constraints. However, understanding how to create and interpret the Solver answer report can be a challenge. In this article, we will explore five ways to create a Solver answer report in Excel and provide practical examples to help you master this skill.

Why Create a Solver Answer Report?

Before we dive into the methods for creating a Solver answer report, it's essential to understand why this report is important. The Solver answer report provides a summary of the optimization results, including the optimal values of the decision variables, the objective function value, and the constraints. This report helps users to:

• Verify the optimality of the solution
• Identify the most critical constraints
• Analyze the sensitivity of the solution to changes in the input parameters
• Communicate the results to stakeholders

Method 1: Using the Solver Results Dialog Box

One of the simplest ways to create a Solver answer report is to use the Solver Results dialog box. To access this dialog box, follow these steps:

1. Open the Solver add-in by clicking on the "Data" tab and selecting "Solver" from the "Analysis" group.
2. Set up your optimization problem by specifying the target cell, decision variables, and constraints.
3. Click on the "Solve" button to run the optimization.
4. In the Solver Results dialog box, select the "Answer" option from the "Reports" dropdown menu.
5. Click on the "OK" button to generate the Solver answer report.

The Solver answer report will be displayed in a new worksheet, showing the optimal values of the decision variables, the objective function value, and the constraints.

Method 2: Using the Solver Answer Report Button

Another way to create a Solver answer report is to use the Solver Answer Report button. This button is available in the Solver Results dialog box and allows you to generate the report with a single click.

To use this method, follow these steps:

1. Open the Solver add-in and set up your optimization problem.
2. Click on the "Solve" button to run the optimization.
3. In the Solver Results dialog box, click on the "Answer Report" button.
4. The Solver answer report will be displayed in a new worksheet.

Method 3: Using VBA Macros

If you want to automate the process of creating a Solver answer report, you can use VBA macros. This method requires some programming knowledge, but it allows you to customize the report to your needs.

To use VBA macros, follow these steps:

1. Open the Visual Basic Editor by pressing "Alt + F11" or by navigating to the "Developer" tab.
2. Create a new module by clicking on the "Insert" menu and selecting "Module".
3. Write a VBA macro that uses the Solver object to create the answer report.
4. Run the macro by clicking on the "Run" button or by pressing "F5".

Here is an example of a VBA macro that creates a Solver answer report:

Sub CreateSolverAnswerReport()
    Dim solver As Solver
    Set solver = ActiveSheet.Solver
    
    ' Set up the optimization problem
    solver.ObjectiveCell = Range("A1")
    solver.Variables.Add Range("A2:A5")
    solver.Constraints.Add Type:=xlConstraintTypeGreaterEqual, FormulaCell:=Range("B2")
    
    ' Run the optimization
    solver.Solve
    
    ' Create the answer report
    solver.CreateAnswerReport
End Sub

Method 4: Using the Solver API

The Solver API is a programming interface that allows you to interact with the Solver add-in using a variety of programming languages, including C#, Java, and Python. This method requires some programming knowledge, but it allows you to customize the report to your needs.

To use the Solver API, follow these steps:

1. Choose a programming language and set up a development environment.
2. Import the Solver API library and create a Solver object.
3. Set up the optimization problem using the Solver API.
4. Run the optimization using the Solver API.
5. Create the answer report using the Solver API.

Here is an example of C# code that creates a Solver answer report using the Solver API:

using Microsoft.Office.Interop.Excel;
using Solver;

class Program
{
    static void Main(string[] args)
    {
        // Create a new Excel application
        Application excelApp = new Application();
        
        // Open a new workbook
        Workbook workbook = excelApp.Workbooks.Add();
        
        // Set up the optimization problem
        Solver solver = new Solver();
        solver.ObjectiveCell = workbook.Sheets["Sheet1"].Range["A1"];
        solver.Variables.Add(workbook.Sheets["Sheet1"].Range["A2:A5"]);
        solver.Constraints.Add(Type: Solver.ConstraintType.GreaterEqual, FormulaCell: workbook.Sheets["Sheet1"].Range["B2"]);
        
        // Run the optimization
        solver.Solve();
        
        // Create the answer report
        solver.CreateAnswerReport();
    }
}

Method 5: Using Add-ins and Plugins

There are several add-ins and plugins available that can help you create a Solver answer report, including SolverStudio, OpenSolver, and XLMiner. These add-ins provide a user-friendly interface for setting up and solving optimization problems, and they often include features for creating custom reports.

To use an add-in or plugin, follow these steps:

1. Download and install the add-in or plugin.
2. Set up the optimization problem using the add-in or plugin.
3. Run the optimization using the add-in or plugin.
4. Create the answer report using the add-in or plugin.

Here is an example of how to use SolverStudio to create a Solver answer report:

1. Download and install SolverStudio.
2. Open a new workbook and set up the optimization problem using SolverStudio.
3. Click on the "Solve" button to run the optimization.
4. Click on the "Answer Report" button to create the Solver answer report.
