Using Excel Solver With Min And Maximum?
Jan 27, 2014I'm having issues getting solver to use the minimum and maximum for hours and items to be produced. I can't seem to get a balance between the two.

Hedging Simulation, Solver To Obtain A Maximum Profit
Apr 18, 2007Im setting up a fixed hedging simulation using excel and want to use solver to obtain a maximum profit. I have taken historical stock prices and then predicted future prices using the random walk process. To create the hedge I am using european calls and puts in both long and short positions. The simulation has been set up so that the options are being brought/sold when the historical data ends and then sold/payed when the predicted data finishes.
I am letting solver change the values of the strike of each of the options and also the amount purchased/sold for each of the options too! My constraints are that all the strike prices have to be >= 0, all the amounts of each particular option has to be >= 0 and that profit has to be >= 0. It is worth noting that as well as the values already mentioned, d1 and d2 values are also being calculated on the sheet which are then used to calculate the value of the options being used (using Black-Scholes model), this value is then given a realistic spread value and then 3% is added on as the brokers fee. All of the values mentioned are being taken into consideration when caluclating profit.
Multiple Solver Constraints In Solver
Sep 10, 2006I 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?
Excel 2010 :: Using Solver / What-if Analysis For Multiple Objectives
Nov 10, 2013I'm using Excel 2010 for Mac.
Here's my problem: I need to keep two values subject to two upper limits (i.e: value 1 < x, value 2 < y).
These two values are equations that are dependant on 3 variables. The relationship between these variables are not linear (i.e.: can't just plot a graph and mark where the lines cross).
Is there any computational method using Excel I can use that will give me the LOWEST value for the three variables in order for my target values to be under their upper limits?
Excel 2007 :: Compile Error / Sub Or Function Not Defined - Even After Solver Has Been Referenced
May 15, 2014I get this error : Compile error : Sub or Function not defined. I found out that this might be caused by the solver not being referenced. But, this is fixed now but I still get the same error message.
I'm using Excel 2007 - Windows.
Here is the code :
Sub Macro1()
Dim i As Integer
Dim j As Integer
j = 4

If ActiveSheet.Cell(i, 12).Value = 1 Then
ActiveSheet.Cell(j, 15).Value = ActiveSheet.Cell(i, 2)

Solver Solver To Calculate Through VBA
Jan 12, 2007I 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.
SUM MAXIMUM Or Index/Max: Count Number Based On The Maximum Time??
Oct 23, 2008I was hoping that my formula would give me the count number based on the Maximum time (latest time) and the Name field...My result is a 0 instead of 62 (the correct answer).
=SUM((Download!$H$2:$H$10=A4)*(Download!$D$2:$D$10=MAX(IF(Download!$H$2:$H$10=$A4,Download!$D$2:$D$1 0)))*Download!$I$2:$I$10)
Would a Index/Match/MAX function be more efficient?
Find MAXIMUM, Show Date When MAXIMUM Occurred
Oct 9, 2008Look in Column E and find the MAX value. Once you find the MAX value, (let's say E27) display the date that's in C27. I bet this is really easy but I've been screwing around with it for over a half hour and can't get the correct result.

May 15, 2009I have two columns of data. The first column is the 'type' and the second column is the 'value'. I need to find the maximum 'value' for each individual 'type'
The 'types' are not necessarily next to each other and the data cannot be sorted to do so.
Example:

I need to be able to say the MAX for 'A' is 21, the MAX for 'B' is 13 and the MAX for 'C' is 7.

Excel 2010 :: Maximum Number Of Nested IF Statements
Jul 29, 20141) What's the maximum limit of IF statements in a formula for MS Excel 2010?
2) I have 8 nested IF statements, but I am having trouble with the False part of the argument. I was able to get the False part to work for the 4th argument (because I simply put a comma and closed it's respective colored parenthesis) but the following 3 I can't seem to get and the following message pops when I hit enter "The formula you typed contains an error."
For the False part of the remaining 3 nested statement which is at the end of the formula I just type:
IF($E$2="Q3"........)))IF($E$2="Q2".....)))IF($E$2="Q1")))
And close it's respective colored IF statement argument. I tried putting a comma at the end of each False part for the arguments but it pops with the message "You've entered too many arguments for this function."
Excel 2010 :: Finding Data With Tied Maximum Scores
Nov 14, 2012i have product group,product name and the statistics. I'll use an example of students with score. I have these set of data:
A B C D
1 Student Name Score Sum
2 Student1 Anna 48 80=Sumif(A:A,A2,C:C)
3 Student1 Anna 32 80
4 Student2 Tom 30 80
5 Student2 Tom 30 80
6 Student2 Tom 20 80
7 Student3 June 55 60
8 Student3 June 1 60
9 Student3 June 4 60
Now we have 2 students with tied highest scores with 80 Scores. Naturally i want the rank to be as follow: Top1 Anna since she has the highest score "48", and Top2 Tom, and Top3 June.
The problem is, the score data can vary and Top3 can probably have the highest score and he still didnt make the highest score collectively. And there will also going to be other situations as well because im working on a very large data set, and not these 3 students.
the max score is tied, and since im making another column with sum scores, the data is going to be redundant, and hopefully theres a formula to ignore this.
Solver- When Solver "changes Cells"
Jan 21, 2009I 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?
Excel 2010 :: Print Hundreds Of 6 Column Charts Using Maximum Page For Printing
Apr 28, 2013I am using Excel 2010
I have over 800+ pages of chart that only takes up 6 columns and around like 9000+ rows.
I wanted to print this chart on paper and need hardcopies. However, the chart in its current setup prints only on the left half of the page leaving the right half empty.
How do i make use of the full space properly? Each chart has a "page number" on it so I want the chart to print continuously from one half of the page onto the next half and then the second page, third, etc.
Here is a visual demonstration of how things currently are and how i'd like to get them to be:
As you can see, This is the first of many charts and its numbered Page 9 and next one is page 10.
Pic1
How this looks when i try to print, it's only on the left side. right is all blank
Pic2
How i want it to look like upon printing
Pic3
As you can see in the last picture, once page 14 chart has no space it automatically continues chart on right side of page and then moves on to print rest.

Run Solver With VBA
Feb 14, 2008I 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.
Sudoku Using Solver Add-In
Jun 2, 2009I 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?

Solver Root
Nov 17, 2008I 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.
VB - Looping Over Solver
Jan 14, 2009I 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:

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.

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.
