I have a spreadsheet which has a list of staff (column B) and work categories (row 3).
Row 4 is updated each day with a count of the incoming work for each work category.
I want to be able to randomly distribute (as evenly as possible) the no of work items in Row 4 between the doers (B7:B13). Each item of work also has to be checked so I would also like to randomly distribute the checking between the checkers (B16:B18)....
i have some number that i want to put in a normal distribution
so.. i have age ( 1, 2, 3, 4, 5, 6, 7, 8, 9, 10) and have the number of times that the kid wake in the night ( 10, 12, 9,11,8,9,7,9,11) and want to do the normal distribution grafic with that .
in VBA the RND function generates a random number using uniform distribution (every number is as likely as any other). Is there a function to generate a random number using normal distribution where the numbers closest to the mean are more likely to occure then numbers further away from the mean. I've created the following custom function to generate a random number between two given values using uniform distribution.
Function RandNum(Min As Double, Max As Double) As Double
RandNum = (Max - Min) * Rnd + Min
End Function
I would like to create a random number based on that data.

I've managed to write a random number generator that produces multiple sets with no repeating numbers per a set.
Now, to step it up a notch, I'm trying to create an even distribution of the numbers generated which is where I could use a hand. Here's my current code:
Code:
Option Base 1
Sub RandomNumberStrings()
Dim rndno As String, strg As String, msg1 As String
Dim r1() As String, r2() As String

Equaling 500 numbers generated as intended, but my target is to get every number with an equal frequency.
how to go about generating random numbers based on Weibull distribution in VBA? I had a rough idea for Normal (from link below) which i later extended to Lognormal but am having difficulty with Weibull and Gamma will appreciate any help.

I would like to get random number generator for normal distribution and I’m using:
=NORMINV(RAND(),$B$1,$B$2)
Where B1 is mean (average) and B2 is SD.
This command works, but in the random generating numbers, I’m getting positive and negative numbers (ex. -23,34).
how to change command so I can generate positive only numbers?
Let say I have 5 shops: A, B, C, D, and E
They request for stock replenishment from warehouse as follows:
A: 4 pieces
B:2 pieces
C:3 pieces
D:3 piece
E:3 piece
But since the warehouse only have 12 pieces of this product so need to allocate to the shops in rounds that is:
Round 1: one piece is allocated to each shops (Stock left=12-5=7)
Round 2: one piece is allocated to each shops (Stock left=7-5=2)
Round 3: one piece each is allocated to A and C (the priority should be B but since B just requested for 2 pieces only which has been fulfilled) since there are no more stock
how to write the scripts to do this allocation.
I have a list of 500 'cases' for staff to work on and I want to auto allocate them to people based on their skills. Whilst I can do this easily with each person have their own page in my workbook, I'm having the issue of the same data being replicated onto multiple sheets.
The main data is on one page and each person has their own individual page for their cases for the day. Is there any way to avoid multiples being sent out whilst creating a kind of 'priority ladder' as such?
I have trying to assign cards to respondents to view. I have 16 cards total which are grouped in sets of 4. Each set (of 4) is given a color, (red, green, blue, and yellow). Each color has a 4 different shades (S1, S2, S3, S4) so I have the following 16 cards:
1: Red_S1
2: Red_S2
3: Red_S3
4: Red_S4
5: Green_S1
6: Green_S2
7: Green_S3
8: Green_S4
9: Blue_S1
10: Blue_S2
11: Blue_S3
12: Blue_S4
13: Yellow_S1
14: Yellow_S2
15: Yellow_S3
16: Yellow_S4
I will have a total of 10 respondents giving their opinions who will each see 5 of the cards, randomly. Each respondents must see each color at least once (given that 5th card will be a repeated color). Each card must be tested 3 times (given that the 2 additional cards can be any of the cards).
If there a function or cell code that I can write so that I can allocate the card #s (1-16) across my 10 respondents?
I am creating a time allocation / holiday tracking calendar. 150 employes (1 per column) and then using rows (10 - 375) as a daily track. I am having trouble with two aspects and would value your assistance.
1. i have locked the top 9 rows and would like row10 to jump automatically to todays date. i.e current info directly below the titles block
2. How do i make the calendar wrap around i.e. if someone puts in for a week holiday starting dec 31st 2007, how do i make the calendar roll round to 2008.
I've been assigned a project where I'm suppose to report inventory allocation to projects at end of day every Thursday. The past 2 Thursdays, I've just literally been manually plugging in the numbers into the allocated stock column.
The spreadsheet I came up with is attached. The 1st tab is the demand showing the needed quantities per item and respective due/on-site dates. The on-hand inventory (stock) is on the 2nd tab. My current process is:
1. once items have been shipped, I delete those entries/rows from the first tab. This way, only all the outstanding/open orders remain.
2. after completing #1, I then copy and paste on-hand inventory from our database (Navision) onto the 2nd tab.
3. I manually plug in the the qty for each item depending on stock available. This is the part that I would like to streamline.

I need a formula for batch allocation automatically.

I am trying to write a Macro to allocate a certain cost across thousands of orders. The number of orders will obviously change monthly. The cost is relatively small, and when divided evenly by the total orders needs to be rounded up to the nearest cent (Typically $.01 - $.02)
I then need the cost to be insered in a colum running next to a total cost column, but I need it to stop when it reaches the total cost and just start adding zeros to the rest of the orders so as not to overcharge.
Not sure if I need to incorporate solver somehow. I figured I would reference the allocated cost from a cell in the worksheet but not sure how to insert any algebraic logic into a macro.
I am reposting this as my previous post was deleted.. i dont know the real reason for the same...
The raw data in the attachment contains:
•C1 to AI1 refers to vehicle numbers.
•Column A refers to Shift Time
•Column B refers to Number of vehicles required in that particulars Shift time
The output:
•As you can see in the Sheet “Output Required”, fields marked in the color “light green” are manually allocated vehicles numbers available and required according to shift time
•The logic used behind allocation is the same vehicle should not be used before or after within the span of 3 hrs, the gap between the vehicle usage before and after should be minimum 3 hrs. And the maximum time gap can be any value.
•Vehicle usage can be maximum (ie. You can use the same vehicle by rotating within 24 hrs but keeping in mind that it is not used before 3 hrs).
• all the available vehicles must be used before the same used vehicle is used in the new shift... ie. You should utilize all the vehicles before one is duplicated
I m creating a single cell formula in 'report'B3 that would allocate 'data'D3 appropriately by month heading if copied across. A few other threads on this topic only acheive this by creating an addtional row, not in a single cell. Since I'm going to use this on a report in Access, I just need the calculation. Is it not possible to acheive this in a single cell?

The task involves summarising about 10,000 lines of data into months by Plant by Process. I can achieve it by stepping through a couple of schedules but I'm sure it can be done using one formula (but I can't find it!).
View 8 Replies View RelatedI'm fairly new to excel and trying to create a simple spreadsheet to provide a log of staff allocation. I've created a first a sheet displaying a table with a week of rota. The first column lists where the staff are placed, the first row the date and inbetween the staff member covering that date. There are 5 further sheets, one for each member of staff with a simple table - first column is date, second is allocation.
Back on the first sheet below the timetable is a further grid showing on the first column staff names, and below each date a formula =VLOOKUP( B$3,David!$A:$Z,2,FALSE) pulls information from the 5 sheets displying whether a memeber of staff is on leave or there allocation on that particular day.
The problem i'm having is trying to get the 5 simple staff sheet to pull data from the Rota ie. I need say B3 to look at the date in A3, find the same date on the Rota sheet, look for the relevent staff name below it (if present), and display the allocation from the first column on the same row as the staff member.
I've tried a combination of Vlookup with Match and Index with Match but nothing seem to work.
On the attached sheet in column X, I am trying to input the Allocation percentage dependent on a number of variables:
Type (Bar, Blank, Coil, Sheet, Special)
Sub Fam Code (2A02, BC02-05, BC99, BZ99)
Sup Category (Arcelor, Independent, Tata/ Corus)
The allocation percentage is based on the below; anything outside of this should result in "Other".
Sheet (BC02/03/04) A=40%, T=40% & I=20%
Coil (BC02 & BC03) A=40%, T=40% & I=20%
Coil (BC04) A=30%, T=50% & I=20%
Example 1:
Type - Sheet & Coil
Sup Category - Independent
Result 20%
Example 2:
Type - Coil
Sup Category - Tata/ Corus
Sub Fam Code - BC04
Result 50%
Example 3:
Type - Coil
Sup Category - Arcelor
Sub Fam Code - BC04
Result 30%
I am running Excel 2010 32bit under Windows 7. The Excel file worked perfectly under Excel 2007 and Windows XP. The Excel file is somewhat complex with numerous links and embedded cell formulas. Occasionally, I get the following error message:
5.jpg
Before I install the 64 bit version, I attempted to chack a few other things. I opened the task manager and while viewing the process tab, I opened my Excel file. Once the file loaded, this is the allocation displayed in task manager:
1.jpg
This seemed reasonable considering the size of the Excel file (33Mb). Without changing anything, I clicked save to make sure it was working properly. While viewing the process, I watched the allocation climb, substantially. when it completed, this is what the process displayed:
2.jpg
Continuing to click the save button, without changing anything, continued to increase the memory allocation until the error message was displayed:
3.jpg
4.jpg
Closing Excel and re-openeing the file resets the memory allocation back to normal, which is a popular solution to this issue in the forums.
I did check the same issue using Excel 2007 and the memory allocation releases after each save.
I can see how installing the 64 bit version of Excel can correct this issue, and with 12Gb of Ram, I will probably use this method until I can get this fixed.
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 know EXCEL has functions for both the NORMAL DISTRIBUTION and the
cumulative value thereof...
but is it possible to graph this data..
(I imagine if I sort the data and then calculate the ***. distributions into

I need a formula that distributes a % based on position.
The positions are 1 through 20, and each one has a corresponding % value ...
I have been working on a problem that requires being able to calculate the chances of any winnng a series of coin tosses with a weighted coin.
The coin has for arguments sake a 65% / 35% chance of landing heads or tails and to win the game you need to hit your side 9 times.
Can you use excel to calculate things like: If heads takes the lead 1-0, what does that mean the its overall percentage chance of winning? If the score is 7-3 to tails, what are the chances of either side gaining victory? etc, etc.
I thought that there would be a way of setting up a spreadsheet that listed the goal (first to 9, 12, 15 or whatever) and below this the percentage chance of heads and the percentage chance of tails. Then somewhere would be a box to enter the current score (0-0, 3-5, 1-1 or whatever) and beside this the current chance of heads or tails gaining victory.
I've tried setting up something like this but am a bit of a dufus when it comes to knowing how, where and when to use the different functions of excel.
I'm looking to analyse is how long these articles take to reach maturity from their date of publication (so, when they achieve their optimum performance).
I'd then like to further analyse this across various metrics like article type/producer etc., which, I guess, would be in some kind of Pivot Table filter-type-thing.
Here's an example of some of my data:
ArticleName - PublishedDate - OctViews - NovViews - DecViews - ArticleType - Producer
Article1 - Oct-08 - 3701 - 4856 - 4561 - Food - ABCTV
Article2 - Nov-08 - 0 - 9824 - 1256 - Food - ABCTV
Article3 - Oct-08 - 1358 - 8953 - 9652 - Tech - XYZ.com
Article4 - Oct-08 - 1351 - 2354 - 3562 - Tech - ABCTV
The part I'm finding tricky is this; what we'd like to do is rather than look at a specific date (say, articles published on 09/04/08) it would be useful to combine all the dates so that the first month something is published is Month 1, regardless of the date it is actually published.
As the same article can be from the same producer but published at different times, if I could remove the "Jan-Mar = Month 1-Month 3" problem it would allow us to graph all the data into one snapshot of the publishing process and find trends. If this could then be cross examinable by the ArticleType etc. it'd be really useful.
Say I measure the height of 1000 people and I have those in a column in excel. It should be a normal distribution with mean x and standard deviation y. How do I actually graph it so I can see the normal distrubution curve that looks something like this:

I tried making a scatter graph but it graphs them point by point. I want the height to be on the x axis and something like frequency on the y axis.
There is trading system which generates a winning trade per ONE stock in ONE month’s time with a probability of 5/12 (0,4166%). If the system trades 10 independent stocks the probability of any number of winning trades occurring out of all of them in ONE month is shown below:
None 0,0046
One 0,0326
Two 0,1047
Three 0,1995
Four 0,2494
Five 0,2172
Six 0,1272
Seven 0,0519
Eight 0,0139
Nine 0,0022
