I need to do a sensitivity analysis using Solver table. It is a one way table and the range of the base input values needs to be -20% to 40% with increments of 5%. I am running Excel 2011 for Mac. I have a Worksheet with a small amount of data, and when I click the Pivot Table button it automatically creates the Pivot Table in a new. The Solver Add-in is a Microsoft Office Excel add-in program that is available when you install Microsoft Office or Excel. To use the Solver Add-in, however, you first need to load it in Excel. Windows macOS Android iOS Windows Mobile In Excel 2010 and later, go to File Options. If you are running Excel 2016 on Mac, you need to install the solvers after unzipping OpenSolver. Inside the unzipped folder, go to Solvers/osx you will find a file called “OpenSolver Solvers.pkg”. Open this file and click through the prompt to set up the solvers on your computer (you will need to enter the administrator password to do so). With this Solver add-in, created by Frontline Systems, developers of the Solver in Microsoft Excel, you can define and solve optimization problems in your Excel workbook, using Excel Online in Office 365, Excel on iPad, Excel 2013, or Excel 2016.

This add-in is a natural extension to the Solver add-in incorporated in Excel. SolverTable performs sensitivity analysis for an Excel optimization model, and, in most cases, its output is more relevant and understandable than the optional sensitivity output provided by Solver itself. (Besides, we have learned that Microsoft “broke” something in Excel 2007, so that Solver’s Sensitivity Report might not be available!)

SolverTable is very easy to use, as I describe below. All it requires is an existing optimization model. That is, there must be a spreadsheet model already built, and the corresponding Solver dialog box must already have been filled in. This document explains how to use SolverTable, and it illustrates the procedure with several screen shots. Note: This version of SolverTable has been developed to work with Excel 2007 (aka Excel 12). You will see only minor differences (in the user interface) from the previous version of SolverTable. This version will not work with previous versions of Excel.

Loading SolverTable

To load SolverTable, proceed as follows:

Solver Table Macro

1)Copy the SolverTable.xlam file and the corresponding help files (SolverTableHelp.htm and the various SolverTable .gif files) to a common folder on your hard drive. I recommend creating a SolverTable folder for this purpose under Microsoft’s Library folder, i.e., c:Program FilesMicrosoft OfficeOffice12LibrarySolverTable, because this folder is in Microsoft’s “trusted” list. If you want to store the files somewhere else, e.g., D:SolverTable, then you should add this folder to the trusted list. (To do so, Click on the Office button, then Excel Options, then Trust Center, then Trust Center Settings, then Trusted Locations, and then Add new location.)

2)(One-time only step) Because of the way Solver works and the way SolverTable invokes Solver, you need to change a macro security setting on your PC. Make sure the Developer tab is visible. (If it isn’t, click on the Office button and then Excel Options. In the Popular group, check the Show Developer tab in the Ribbon option.) On the Developer ribbon, click on Macro Security and make sure the “Trust access to the VBA project object model” option is checked. (As long as you’re there, I recommend that you check the second option in the top group: “Disable all macros with notification.”)

3)In Excel, load SolverTable into memory. There are two ways to do this. Regardless of the way you use, you will know that SolverTable is loaded when you see a SolverTable item on the Add-Ins ribbon.

a)Open the SolverTable.xlam file directly by double-clicking on it in Windows Explorer. If this file is buried way down in some folder, this way might not be very convenient, but you can accomplish the same thing by putting a shortcut to this file on your desktop, so that it’s just one click away. The advantage (or disadvantage?) of this method is that if you then close Excel and reopen it, SolverTable won’t be loaded; you’ll have to load it again.

b)Click on the Office button, then on Excel Options, then on Add-Ins, and then on the Go button at the bottom. Here you see the familiar Add-ins dialog box from earlier versions of Excel. If this is your first time to load SolverTable, you will need to click on the Browse button to find the SolverTable.xlam file. Otherwise, there should be a SolverTable item in the list of available add-ins. Just check its box, and click on OK. The advantage of this second method is that if you then close Excel and reopen it, SolverTable will open automatically. In fact, it will keep opening until you uncheck SolverTable on the Add-Ins list.

Note: In previous versions of SolverTable, there were two add-in files, SolverTable and SolverTable1. The current version simplifies this, so that there is now only SolverTable.xlam.

Unloading SolverTable

To unload this add-in (remove it from memory), just close Excel (if you used method a) above), or uncheck the SolverTable box in the Add-ins list (if you used method b) above).

An example file

To illustrate SolverTable, I will use the standard product mix model, a version of which appears in Figure 1. (The conventions I use are that the inputs are in blue borders, the changing cells are in red borders, and the objective cell is in a black border, but you can use any conventions you like.) I assume the Solver dialog box has already been completed in the obvious way (including checks in the Linear and Non-Negative boxes). Actually, this model has already been optimized, but this is not necessary for running SolverTable.

Figure 1

Running SolverTable

The purpose of SolverTable is very much like that of an Excel data table: to vary one or two inputs and keep track of one or more outputs. The main difference is that SolverTable runs Solver for each input value (or combination of input values) and reports the optimal results in the table. Like data tables, there are essentially two options: oneway tables and twoway tables, depending on whether there are one or two input cells. However, unlike Excel data tables, there can be multiple output cells for oneway and twoway tables. In the latter case, SolverTable creates a separate table for each output cell. Note that a table created by SolverTable retains no links to the original data. If you want to change anything about the table, you must rerun SolverTable.

Creating a oneway table

To illustrate a oneway table, I will see how the optimal profit and the optimal product mix (changing cells) vary as the number of labor hours available (cell D21) varies from 2000 to 8000 in increments of 1000. Begin by selecting the Run SolverTable item from the SolverTable dropdown on the Add-Ins ribbon. You will first be asked whether you have a Solver model on this sheet. For this example, you should say Yes. But if you inadvertently ran SolverTable on a sheet without a Solver model, this would give you a way to back out gracefully. You then see the dialog box in Figure 2. Fill it out as shown and click on OK.

The next dialog box, shown in Figure 3, requires you to specify the input cell, the input values (whic
