Hi all,

Now the sensitivity analysis table is created as below screenshot shown. You can easily get how the profit changes when both sales and price volume change. For example, when you sold 750 chairs at price of $125.00, the profit changes to $-3750.00; while when you sold 1500 chairs at price of $100.00, the profit changes to $15000.00.

After the solver found a solution, you can create a sensitivity report. Before you click OK, select Sensitivity from the Reports section. Below you can find the optimal solution and the sensitivity report. Do NOT use Figure 3.20 to answer the questions. Generate the optimal solution and sensitivity analysis report using Excel Solver. Answer all parts of the question in the same Excel file. Label each part. The Sensitivity Report provides classical sensitivity analysis information for both linear and nonlinear programming problems. It is available for models that do not contain any integer or binary constraints (which we will learn about later in this course). In this module we will focus on the Sensitivity Report for linear models. An example of a Sensitivity Report generated for a simple. Now I want to generate sensitivity report for the objective function. I found excel solver generates a very well detailed and organised report. On the similar lines how do I generate the reports using Gurobi (python). Regards, Vaibhav. Comments 3 comments. Sort by Date Votes.

1.open the excel and save(ctrl+s) your file(current document).
2. open the solver give the input(tgt. cell, deci. var. etc.)
3.hit the solver button.
4. The solver displays solution.
5.Click 'OK' (don't open the answer,sensitivity or limit report).
6.close the solver dialog box.
7.Open the solver dialog box and hit 'solve' button.
8.Then try to open the answer,sensitivity and limit report. It works 5n.

No. I still have the problem. I am not sure where else to look for the
answer. I will be nedding this capability for a course I teach that is coming
up very soon now.

If you find an answer independent of this thread, I would really appreciate
a note here. I will do the same.

I can't believe we are the only two that are being affected by this!?

If you have a space in the workbook name, experiment by renaming your
workbook without any spaces.
Also, don't call your subroutine 'Main' if it applies.
Again..just some ideas.

Hi Dana,

That is strange and I would really like to adopt that as a workaround, but I
know absolutely nothing about recording, writing or using vba macros. Could
you walk me throught it or point me to a reference that I could use?

I would realy appreciate any help beyonfd he great help you have been with
this post.

Hi. Ok.
1. From Solver's worksheet, Hit Alt + F11 to bring up vba editor.
2. Vba Editor Menu..Insert | Module
3. Paste a copy of Code into this module.

4. Vba Editor Menu.. Tools | References.. and select 'Solver'

(This allows Solver to run)
5. Select anywhere in the code, and Hit F5 (Runs the Macro)

Save workbook.

This may not work, but.. who knows. :>~
There are certain things in Solver that require no spaces in the workbook
name, that's why I suggested it earlier.
Hopefully, this will spark an interest in learning Vba.

First, thaank you for your help. I loaded your first subroutine and it worked
as you described. After generating the reports, I saved the spreadsheet,
brought it back in and then was able to resolve the problem and re-generate
the reports.

I brought in a new spreadsheet, ran Solver and the error was back as I
expected. So I loaded/ran your first subroutine and it fixed up that
spreadsheet.

So as of right now, I see how to fix the problem, one spreadsheet at a time,
which way ahead of where I was.

I am not sure what or why your other subroutines are doing. I did not try
them. Ideally, it would be nice to run a subroutine once per session and then
at least for that session of Excel all of the spreadsheets used would run
properly. Is that what your other subroutines are doing?

BTW I did hacve to lower the security level in order to run the subroutine
on the second spreadsheet.

Hi. Glad it worked. I am not sure why the corruption.
I have been working a little on trying to figure out why my subroutine that
loads the Solver Add-Inn no longer works. I cannot figure it out. Again,
it's a Excel 2007 issue.

If you are interested in Macros, you may be interested in the following:

You can have a 'Digital Signature' that allows you to put the security level
back to high.
Go to
C:Program FilesMicrosoft OfficeOffice12

And run.
SELFCERT.EXE

Type your name in the box.

When working on a workbook with Macros,
go to the vba editor and select:

Tools | Digital Signatures
and choose your name.

Save & close your workbook.

You should now be able to re-open your workbook without the security
message.

Dana,

Sorry to bother you again. Everything worked ok with your 1st S/R yesterday,
but today, trying it on a new spreedsheet, things aren't working.

When I do your Step 4, there is no Solver in the list.

I have tried it several times. I am doing something wrong, but I don't know
what.

TIA

Re: Excel 2007 Solver Internal Error When Generating Answer Report

Ref: >> 4. Vba Editor Menu.. Tools | References.. and select 'Solver'

Hi. When one starts a new session of Excel, and you want to write Solver
macros, here's what you do first.
From the worksheet, select the Solver Analysis Tookpak. This loads Solver,
and makes it visible for the vba editor.
Now.. go to vba, Menu, and do Tools | Reference, and select 'Solver.'
Solver should now show up in the list.

I've have a problem setting this up automatically via vba with 2007, so I'm
sure there's a issue here I am not familiar with yet.
Anyway, hope this helps.

Excel Solver Internal Error
You have to create a macro in the personal workbook and reference it back to the Solver add-in for it to work.

Directions:-

1) Open a blank Excel Workbook

2) Un-install solver add in (Go to excel options, add-ins, at the bottom you'll Manage: with a drop down list, select 'Excel Add-ins' in that list and click on the 'Go..' button. From there you can uncheck the solver add in and click ok

3) Get back to your worksheet and press Alt+F11 to get into Visual Basic.

4) If project explorer on the right side is not displayed, press Ctrl+R to display it.

5) Find 'VBAProject (PERSONAL.XLSB) and insert a new module under the 'Modules' Folder

6) Enter the following code into the module:-

Sub SolverFix()
Application.Run 'Solver.xlam!Auto_Open'
End Sub

7) Hit F5 and to ensure that there are no bugs in the code.

Reading Sensitivity Report Solver

8) Once the code runs without any issues,click anywhere on the code and go to the Tools --> References menu

9) In the references window, click on 'Browse' on the right side.

10) In the drop down list for 'Files of type' select - 'Microsoft Office Excel Files'. Then navigate yourself to the folder where the solver add-in is kept (Typically it'll be Program Files --> Microsoft Office --> Office12 --> Solver) and select the 'SOLVER.xlam' file

11) Once you have returned to the References window, and you see SOLVER in the list of 'Available References' and you have made sure it is checked, click 'OK'

12) Save the VBA project, save the workbook and exit excel.

13) Restart excel and when you run solver, reports should run with no errors. Lord of the rings war in the north.
