I have a proyect evaluation. I use solver to find a value, which works. I recorded a macro for this situation (which repeats all the time), but when I run it, it does not work. The problem is not the answer, it is that the macro does not run
Sub TIR()
SolverOk SetCell:="$M$41", MaxMinVal:=1, ValueOf:="0", ByChange:="$C$44"
SolverSolve
Range("E44").Select
End Sub
I would like the XL add-in 'Solver' to automatically find a value 'M' in the equation attached, based on 'R' being 30%.
I also would like to be able to manually enter 'M' based if I would like 'R' to be different from 30%.
How can I program this in VBA, and have the equation automatically done in the first instance simply by clicking on cell 'R'.
I'm trying to use solver to find the minimum value of a cell by changing 5 separate cells. These cells are subject to a set of constraints that are formulae. On top of that I have a large number of these solve's to run (The spreadsheet is creating randomly distributed data to form a Monte Carlo simulation). Therefore I am referencing the formulas using the ActiveCell, Offset() function. For some reason when running this code none of the values are changed. Also I changed the UserFinish to false so I could see what solver was doing at each solve, It stops at the correct cell (one after the final cell) but without me having to confirm it each time.
Here is the ....
I have a nifty formula brought to me by one of the excellent members on this board. It works perfectly for what I want, but I must admit I cheated, I have a problem that was similar to the problem this formula rectified and I find myself not knowing how it works.
=IF('IIC Transfer Status'!O139="x",MIN('IIC Transfer Status'!K139+10-WEEKDAY('IIC Transfer Status'!K139-{1,3})), "" )
What Im wondering is if someone could enlighten me as to what is happening in this function, so Im not as blind to assume it is magic.
Eventually I need it to be customed tailored to work in this way: I have a column of dates, I want it to look at column A and if there is a date in it ADD 4 WEEKDAYS (business days) and return the resulting date.
i.e date in column a is march 19 plus 4 business days. Result in column B march 23.
If someone can explain how this string works that would be great, or if someone could just post a suitable function, that would work for now.
I'm having trouble using VBA's Find function.
I have a worksheet which holds a concatenation of AppID's and App Names in Column U. There are approximately 12,000 rows and each cell in Column U holds one of either of the following value formats:
242 - Application 1
242 - Application 1; 1845 - Application 2
242 - Application 1, 1845 - Application 2; 34678 - Application 3
etc...
I need to find all instances of a chosen App ID and then copy any row in which the App ID appears to a new sheet (to obtain the chosen AppID I am presenting a list of those to the user in a form Listbox, and I know the selection ofthe AppID is functioning as I am currently presenting it in a MsgBox prior to running this part of the code).
When I run a manual FindAll on a given AppID it returns all the cells in Column U which that AppID appears, but when I use the following code to achieve the same it does not seem to find the AppID's.
(NB - I've "borrowed" this code from a posting on Ozgrid, but I have also compared it to the many other FindAll methods available on the web and they all apppear to be pretty similar).
(The changing of the cells interior colour is just a way of identifying whether it's working prior to writing the code to copy the row ino a new sheet).
Dim temp2WS as Worksheet
Set temp2WS = ThisWorkBook.Worksheets("AppID")
Dim lCount As Long
Dim rFoundCell As Range
Set rFoundCell = temp2WS.Range("U1")
temp2WS.Activate
I am trying to write a function that searches a column for an index then sums the value in a corresponding column. This function works when run in the immediate window of VBA but when I use it in the spreadsheet it can't find any rows.
The reason I need this formula is because there are more than one rows that can be found.
Function SumIndex2(ByVal sField As String, ByVal sIndex As String) As Double
Dim i As Integer
Dim dSum As Double
Dim rng As Range
Dim firstaddress As String
I have a cell, D5, which is the sum of three other cells, A5 B5 and C5. (all currently empty). Cells A1 through C4 are filled with various numbers.
What I've been trying to do is use solver to say: Make D5 equal 200, do it by manipulating only A5 B5 and C5, and make it subject to the constraint that A5 must equal a value selected from A1:A4, and B5 must equal a value from B1:B4, and C5 ...etc. I have deliberately set it up so that there is only one solution.
I was doing fine until trying to create the constraints. How can I make a constraint that says "this cell" must equal "one of the following cells"? And if I can't do that, is there an alternate method of achieving the same result?
I have this code attached to a button on the first sheet of a workbook with hundreds of sheets.
it is suposed to look for a cell that contains "SAY:" and then move one column to the right and make it a zero. It works on the first sheet but not on any other sheet.
I have to use use the solver to calculate something (a mean-variance framework).
I am using the solver to minimize a cartain cell (variance) by making two cells equal through (expected return) by varying 10 cells( weights of assets), but I have to repeat this for 500+ times (for different expected returns).
Someone told me that I could best use some sort of loop through VBA. But I don't have a clue how that works.
I want to use solver program. But when solver "changes cells" i want it to trigger my pivot tables in the workbook. So i added the code to my worksheet:
Private Sub Worksheet_Change(ByVal Target As Range)
ThisWorkbook.RefreshAll
End Sub
So when a change occurs, all my pivot tables will get refreshed and my data will change. Is solver able to trigger this event while solving an optimization problem?
I am trying to drive Solver in Excel 2000 with a Visual Basic (version given as 9969) macro. SolverReset is observed, and SolverAdd puts the constraints in. But the SolverOK statement does nothing, so the SetCell and the ByChange windows stay empty.
SolverSolve is trying to do something, because the spreadsheet cell that should receive the return code from Solver gets an error value #VALUE! (The macro then stops, unable to process this entry.)
Solver is checked off ok in the References list in V.Basic.
The same macro, same spreadsheet, in the same Excel file, works fine on the other computer in my office with what I am told is a more recent version of Excel; i.e. this doesn't look like a coding error.
I wanted to see if I could use the solver to Solve Sudoku puzzles. I created the attached workbook. First it colors the numbers that are put in manually, which would be the starting puzzle. I have a generic one put in now. Then it finds which cells that are allowed to change. Then it is supposed to solve. It doesn't work. Run the Sheet1.SolvePuzzle Macro to see it not work. Is solver just not up to the task, or am I missing something?

I created a trendline and associated equation for some data plotted against Time on the x-axis displayed in MM/DD/YY format. The date for the data ranges from 3/27/06 thru 11/10/08.
The trendline equation is
F(x)=-6E-13x^5+1E-07x^4-.0087*x^3+329.1*x^2-6E+06*x+5E+10
The data actually crosses the y=0 line around 11/5/07, which is the data root
When I use Goal Seek, I got a zero root solution of 28154.98. When I convert this to the date format, it converts to a date in 1981 which is not correct. I tried a range of initial guesses but they all converge to the same number.
I am using solver to solve an optimisation problem I have. I need to apply a new solver to every populated row of my sheet. My solver code is as follows:
Sub solverloop()
SolverOk SetCell:="$Z$2", MaxMinVal:=3, ValueOf:="0", ByChange:="$N$2:$O$2"
SolverSolve
End Sub
The code above applies the solver to row 2. My sheet has roughly 500 populated rows. I need to write a macro to loop solver over each row, accept the solution provided by solver, then move to the next row. i would also like to close the loop automatically when the last populated row is reached.
I'm trying to run a macro which will allow me to run solver and keep the solution.. I have managed to get the macro to work. However, does anyone knows how I can ensure that solver's solution can be automatically saved without prompting the user whether to save the solution?

Excercise:
Eve Blue is the manager of Southland Furniture store and she is planning a New Years Day sale. The store has only 75 square feet of space available to display and stock this merchandise. During the sale each folding table costs $5, retails for $11 and takes up two square feet of space. Each chair costs $4, retails for $9 and takes up one square foot of space. You must order at least one chair and one table and, of course, they must be whole units. The maximum amount allocated for purchasing the tables and chairs for the sale is $280. Eve cannot sell more than 40 chairs but the demand for tables is unlimited. Eve asked you to help her determine how many tables and chairs she should purchase in order to make the most profit.

I have the following dataset and was wondering how I can run a constrained regression in Excel with the constraint being that the total allocation of assets is 100%:
Total return (y): 12 data points
Asset 1 (x1): 12 data points
Asset 2 (x2): 12 data points
Asset 3 (x3): 12 data points
Asset 4 (x4): 12 data points
Asset 5 (x5): 12 data points
Asset 6 (x6): 12 data points

I have a problem with a macro in Excel 2007. It invokes
solver and creates an answer report. Please find the VB
code for macro, below.
When I run a group of macros for some reason after the marcro runs and I hit F2 excel crashes.
I have figured out that it is one of the marcros that makes the excel crash. It is only when I run the solver application. The code is below. Any thoughts why hitting F2 after running this marcro would crash the machine?
See my file. I want to calcuate a % needed (20%) to add to a another material. Should be easy but I can not figure it out.
View 3 Replies View RelatedMy macro uses the solver 100 times. Everything is working well, but it's a little bit slow because of all the cell references.
I was wondering if it's possible to use the solver with variables without cell references?
Can embedded macros be found within the new Solver and how would you make the changes you need in VBA with different constraint analysis?
