Im an using excel to run a simulation of demand over a period of 200 days. i have an average daily demand of 7.75 and a stdev of 2.6. Is there any way to generate random numbers (for daily demand) based on this data?
View 3 RepliesI am trying to create challenge/response cards. Each card will have a 5-digit number in the upper-left and lower-right corner along with a series of rows containing a line number and 3 pairs of challenge/response words.
Rather than have have copies of these cards, I want the central office to have a macro-enabled workbook wherein they can enter the two numbers from the card and have the challenge/response matrix regenerate on a worksheet.
So, essentially, I want the challenges random number generator seeded from one of the 5-digit numbers and the responses random number generator seeded from the other 5-digit number.
I am trying to use
Code:
Randomize(Seed)
where Seed is one of the 5-digit numbers.
The problem appears to be that, no matter what I use for Seed, the RND(-1) function is not resulting in different numbers.
I am using Excel 2007 and Excel 2010.
I am working on a Random Cycle Count Generator that provides random SKU#s based on 3 separate columns of SKU listings. The user clicks a button to generate the SKU#s to cycle count for that day. What I would like to see is a date stamp in the columns next(B,D,F) to the referenced SKU listing(A,C,E) based on which SKU#s are generated. This will let me see the last date that the SKU was generated. I would also like it to automatically save after generating.
View 2 Replies View RelatedI have a mastersheet that once I open I would like to generate a 3 digit serial number in cell C22. Once this file is opened and the number is generated I do not want the number to change at that point. I have a macro to save the file with data in certain cells. Once this macro is run and the file is saved I will need to be able to open that file to view info but the serial number can't change.
I would like to do this without an add-in so that any client can use file no matter there settings if possible
Here's what I'd like to do:
Have 10 columns... one column would be for the "1s", another for the "2s", another for the "3s", etc...
But I don't want to have them in straight order (i.e. 1 x 1 =, 1 x 2 =, 1 x 3 =, etc...) because the pattern is easily memorized, no matter what number he's working on.
I'd like to be able to hit a button (or something) and have each column shuffle (or randomize) the order in which the equations will be displayed.
So, a column might come up 3 x 6 =, 3 x 9 =, 3 x 1 =, 3 x 4 =, etc...
And next time it might come up 3 x 5 =, 3 x 2 =, 3 x 4 =, etc...
This way he won't be able to memorize any patterns and he'll actually need to learn his multiplication tables.
I am looking for a product that uses excel to create a random test form a bank of questions. I have 50 questions in all and I need a random test of 35.
I can and have messed around with the following. Excel 2012

Random Question
I could even shorten it a bit by placing like this. MATCH(SMALL($A$2:$A$4,B2),$A$2:$A$4,0). Of course this is only the start and it would have in column B 1-50 and in column C&D 1-35 for the selection process. Then I was going to set up on sheet 2 my list of questions 1-50 and my idea was to use 1.1, 1.2, 1.3, & 1.4 for the answers to question 1 and then vlookup. so that when and if question 1 is part of the 35 random then I could pull the answers over as well. but as I started the 'animal' will get bigger and bigger fast.
I am creating 100 random portfolios from a list of 10 assets. I have the return history of the 10 assets and I'm able to calculate the mean and standard deviation of each asset as well as the covariance/correlation between each of the 10 assets. I want to choose to portfolio with the least variance as well the portfolio with the lowest and highest return.
Would it also be possible to introduce a limit that constrains the maximum allocation to each asset at 25%?
I have 800 rows of patient information, I need to sample 70 patients. I used the Random.org randomizer to get my 70 patients. That randomizer only gives me the line numbers such as 1, 8, 23, 45, 70, etc. I then need to go to Excel and just pick out the patients on those lines I was given above. Is there an easy way in Excel to have my spreadsheet of the 800 rows and create a (simple) calculation that will pick out the line numbers that I need all at once, so I do not have to go thru manually and choose the data from row 1, 8, 23, 45 etc to make my new spreadsheet with only my sample patients on it. OR is there a easy way to pick 70 random lines from a spreasheet..
View 1 Replies View RelatedI have some VBA (using Excel 2007) that deletes and re-creates a bunch (20-ish) checkboxes in a spreadsheet. Since i'm using the controls-based checkboxes, Excel defaults them to object names of "CheckBox1, CheckBox2, CheckBox3, etc" as I create them the first time around.
Later on, i clear all checkboxes and implement the SAME checkbox-creating code to re-create all or some of the checkboxes, but Excel doesn't number them in order the second time around! I end up with something like "CheckBox2, CheckBox19, CheckBox3, CheckBox12, etc."
What could be causing my code to create things out of order the second time around? Is there a way to reset Excel's Checkbox-numbering iterator?
The code i'm using to create checkboxes is:
Dim x As Long
Dim BoxCell As String
BoxCell = ""
x = 0
'j gets passed into the sub as a "Long" somewhere between the values of 5 and 35

I am looking for a way to create a random order of numbers in a given range. For example, A1:a100 to be populated with a random number between 1 and 100, but not to duplicate, using every possible number within that range. I use the RANDBETWEEN function to generate the numbers, but I cannot prvent them from duplicating.

View 9 Replies View RelatedI have build a system that needs a lot of random numbers generated to work.
I have used what I thought would work to generate me these numbers like this example:
VB:
Lastrow = ThisWorkbook.Sheets("RPlay").Range("A" & Rows.Count).End(xlUp).Row
RPlayerNum = Int((Lastrow - 2 + 1) * Rnd + 2)
This would generate a random number into RPlayerNum variable, based on the list in sheet RPlay, missing off row 1 as the header.
However we have noticed a massive flaw in this code.... It works as long as the excel file is open, each time run it gives a different random number. However if you close the excel file and open it, then run it, it ALWAYS gives the same number first run, every time.
I am creating an excel spread sheet for a project I am doing, I need to create a daily chart for 6 months of water usage that results in averaging set targets.
I have made a chart with the average uses per day but would like to have daily numbers that average out to what i have but in a random sequence e.g. i have that a shower uses 320 litres per day for 2 people is there a way i can make a chart that says: 300 (a1) 340(a2) 260(a3) 360(a4) etc i need to do this for 180 days with random numbers generated to average the same overall. I dont know even how to generate random numbers.
Any way to make say cells A1 thru A10 produce random numbers from 0 to 9.
I would like to do it without a macro if possible. I also need a button to generate those random numbers. I know this button may make it impossible to not use a macro. If it has to be done with a macro then so be it.
I have a process that generates the value X in cell A1 randomly. So I can change the value of X in A1 by clicking on F9. I want to sum a sequence of X values. I can do this by manually copying each X to a row of cells and then summing the row values. But that is tedious. Can the summation be done automatically without being regarded as being circuler?
View 8 Replies View RelatedI am trying to generate random numbers between 0 - 9 in ten cells that do not repeat an always include every value 0 - 9 (0, 1, 2, 3, 4,...9). The object is to have the numbers randomize each time. So cells A1:A10 could look like this:

I have two rows in a sheet with random numbers (1 till 90).
Those numbers in those two rows I change them every 5 minutes with new one still from 1 to 90
I need a "way", in one side of my sheet (lets say in column B) to count how many times a number was repeated after finish my work (example after 2 hour's)
Is that possible with excel 2007?
I want to set up a column of numbers that will be random without any repeating numbers.
Example: If I set up for 1,000 rows, I would like the random numbers to be 1 to 1,000, but the catch would be to have no duplicates in the column.
It has been several years since I worked with Excel and I am sure this can be done with a macro, but I am not sure how to go about it right now.
I'm trying to generate random numbers that will add up to a certain number and am having trouble brainstorming how to do so. For example, I'm trying to get a+b+c=6 with a, b, and c randomly generated to add up to 6.
