Is it easier to use the Solver Add-in than to create your own data analysis code? We are planning to design a scheduler for around 12 technicians in our contact center (doing phone support).
View 5 RepliesI'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?
in excel, is there a place called data analysis under tools? im an exchange student in sweden andthe work that teacher gave me is half swedish and half english.. im looking for histogram there.

There are few problems i am facing like description has all the vehicle details which are not in any particular order, even if some how i manage to separate these then too many variables are not letting me come to any conclusion for example make, model, mileage, year of registration color of vehicle, auction sold, sale price, cap (bench mark for pricing).
what i need to produce is which auction sells certain vehicles best or which color of certain model sells best.

I want to take a shot at this spreadsheet exercise. Setup similar spreadsheet models.

I've done quite a bit of research in the past week or so on the topic of solver automation using loops; while there are a few good posts scattered around, i haven't quite found the solution to my problem.
i'm trying to run the solver on a few like-sized datasets contained in one worksheet. i've set up a loop to properly reference the 4 datasets. the solver constraints are in one column on the same worksheet.
the macro runs with no errors, but it doesn't "solve." the parameter cells retain their original values.
i should mention that my macro ran perfectly before i consolidated the 4 separate solver calls into one loop. I got tired of having to type 4 different constraint changes in the code as i was optimizing the solver.
on a similar topic, does anyone know how to call a variable in the FormulaText declaration? If i wanted to step through a defined array of constraints, say [1,2,3], how do i get FormulaText:= variable to work?
Sub Macrosolver()
Dim iteration As Long
Dim i As Integer
i = 8 'start in row 8 at first dataset
my excel sheet runs through different cases (i=1 till i=20). For each case I need to use the solver. Since the whole programm works with references like this cells(10 + i, columnindex).value I tried this with the solver, too. e.g.: SolverOk SetCell:=Cells(20 + i, 46), ValueOf:="0.000001", ByChange:=Cells(20 + i, 47)
But it gives me not a right result as it would give me with a reference like
SolverOk SetCell:="$AT$21", ValueOf:="0.000001", ByChange:="$AU$21"
I tried difference referencing things with different types of brackets, wih range, etc. but I could not figure it out hwo it might works.
Hi there, I would really appreciate the help with being able to enter a code and having Excel find a match. I have attached a simple example of what I aiming for.

Suppose that you have some data points and you want to fit a straight line to them. You write the line's equation in the cells ajacent to your data points, make the square of each difference, sum up all the squares and you have your objective function. Of course your line equation depends on two parameters, that you enter in two cells. Then you run the Excel Solver, enter your objective function as target cell to minimize, enter the range containing your parameters, set your constraints and off you go.
So far so good.
And now suppose that in order to generate your model data it is not enough to write a straight line equation in some cells, but rather to run a complete reactor model (contained in a macro). How do I couple that model-generating macro with the Excel Solver? Now, I actually found a solution. I wrote a Worksheet_change macro in the sheet containing the model parameters, which calls the model-generating code each time the parameters are chenged by the Excel Solver. This has worked fine for a simple example as the straight line one.
Now one of the two:.....
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 am using following code to apply data validation list. However this code gives error Intermittently. The error message is 'Application defined or Object defined error'. Also this code looks little cumber some. Will really apprciate if any one can put some ligh on why is this error appearing sometimes. Do I need to change something in the code or add few extra lines. I feel following points will be necessary when you check my code
1. The data of validation list is stored under the column heading 'Reported_By_List'
2. Validation is applied on the range under the column heading 'Reported Through'
3. Start and last Cell Address Of the cells of the column in which data of validation list is
stored are extracted into the variables 'StartCellAddress1' & 'LastCellAddress1 '
4. Start and last Cell Address Of the cells of the column on which data validation will be
applied are stored are extracted into the variables 'StartCellAddress2' &

I am trying to do some analysis on montly bank account data. To do this I need to take the bank statement information for the month and put it into a table that shows every day of the month (see attached example).
I am currently doing this manually but I'm sure there must be a smarter way of doing this.
Data Analysis . I have 7 tables gathered in one spreadsheet but in seperate sheets. Tables have the same columns but different data baceause they come from different locations. Now I would like to create pivot table to combine data from all 7 tables. I read a little and I got to know that relationships is needed between the tables but I can't create it because I don't have unique data in the table. Usually tables consist repeating names, locations, some numerical data.
For example every table consists worker's name. I create pivot table from one of 7th starting from worker's name in row field and put some data in value field. Then I add another workers from another table. I can do it but when I put in row field I have workers from second table under those from first one. And of course data are badly calculated. I would like to have all workers in row field with proper data. It means one column with all workers from all 7 tables an then some their data
I know I can copy all of them into one big table and then create pivot table but this is solution what I wanted avoid. I know it will work but these data can change from time to time and it will be very hard to maintain spreadsheet. When data will change I will have to copy manually .Is there any solution to create such a pivot table from multiple tables sources but with the same column structures?
For my thesis I collected data of football players. I have the data in an excel file, but it is unstructured. Due to the nature of the dataset, I don't want to sort it out by hand. The result should be that the dataset is ready for statistical analysis. I have three categories, namely; Player_Performance, Player_Profile and Transfer_History. I will discuss them now.
Player Performance
In this excel file the performance data of the player is gathered. As you can see, the player ID and the player name are a row above the performance data in different competitions. This data should be on the same row. Player ID, Name and then the performance data. How can I achieve this?
Player Profile
The player profile file is the easiest. I want to delete the double information. Some players are 2 times in the file. I want to delete every row which doesn't start with a player id. I also want to remove player id's which arent followed by player information.
Transfer History
The transfer history is the same as player performance. In the first row you will find the player id and name, and beneath are the different transfers. I want to put every transfer in a row of their own. The row should start with player id, then name and then the transfer. So it is possible that one player id will be on more rows.
In the attachment I put the files as they are and three files of how it should look like.

I need to extract for each individual dive: Onset/start of dive (when the whale has completed its surface interval and begins its descent)
Rate of Descent (meters/second)
Onset/start of bottom phase (the whale has stopped descended and begins the "foraging" phase of the dive...not necessary the deepest point reached)
Number of lunges (you can see these if you plot the data. They are lunges at depth indicative of feeding behavior)
End of bottom phase (begins to ascend)
Rate of Ascent
End of Dive (surface intervals begins)
I've attached a brief sampling of the data in case you're curious.
Over the years I have identified these points through visual inspection of Excel charts. It's very easy, but extremely tedious and not at all efficient. I am interested in expediting this whole process and am more than willing to learn programming (i.e. visual basic or the like)...but only IF it is the best approach for this application.
I have attached two dives worth of data, so we can see what the data looks like. Each data set can contain from 1 to 8 hours worth of data.
I have student demographic data, then I have to track how each student did on each question, but each question also corresponds to a reading standard and I need to pull two pieces of info from that. How they scored on the assessment (# of answers correct), and if they missed a certain standard twice or more (There are 4 instances of StandardA in the test and they had wrong answers on 2 or more of them). I have the solution to the first part. I entered the results of each question as a 1 for correct and 2 for incorrect then did a countif and only counted the 1s. I am stumped on getting an analysis of how each student did on the indicators. Since the indicators can occur more than once, generating a pviot table doesn't work in this instance, it'll count of 1s and 2s for StandardA, StandardA2, StandardA3, etc. and not the counts of 1s and 2 for all instances of StandardA.
Example:
What I want:
For student Bob - Number of times he answered incorrectly StandardA, StandardB, StandardC, StandardD, etc.............
Each month we receive an updated budget which includes info for every month of the budget year. I want the user to be able to select the column (which relates to a month) that they want to use for the analysis. I will use the data in this column only for analysis. How can I do that?

View 2 Replies View RelatedI 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 am trying to write this macro so that I can optimize 181 outputs based on 2 inputs (columns A and B are inputs). Each row has a single output at the end of the row that I am trying to minimize. I want to be able to select as many of the rows that I want and have the code optimize each individual row. So far I can't get it to let me use variable cell references for the "ByChange:="$A$3,$B$3"." This is the hang up that is not letting me increment the macro to the next row. The macro works currently for the single selected cell, but until I can vary the ByChange portion, I can't automate it.
