Availability Calculation
Apr 16, 2007
Has anyone got a spreadsheet that will calculate the availability of a server based on its hrs of service. Currently my spreadsheet will give me the availability of a server who's service hours are 24/7 however I have servers that are only supported 5 days a week between 07:30 and 18:30 and so only want to calculate failures that occur during that time when it comes to Availability.
I would of thought there would be a program on the market that does this but I haven't come across it and our company are kean on ITIL.
So to summarise, I key in downtimes every day what ever time of day they are but I want calculations on availability to only take in to account failures between 07:30 and 18:30 on certain servers.

I am doing a program for a car rent company (made up one).
What my problem is when a customer reserves a vehicle and another customer also wants to that same vehicle they should click on check availaility button to see if that vehicle is available or not.
way it should work is once one customer has reserved a vehicle with a specific start date and end date the button checks the vehicle, start date and end date and give a message to the customer tell them if the vechicle is available or not.
I have started it off but i am stuck in creating this function.
Here is the link to my program

I modified an employee schedule that I found on here to meet my needs but I am needing one more thing:
I need a field (or separate worksheet in the workbook) where I can enter employee availability and if they are unavailable for a specific day, it will auto update in the calendar stating they are unavailable for that day.

Attached is an excel file (test.xls) which shows work schedule (Week wise) of a person for two projects.
Now by looking at the sheet we can see the John is available from Work Week 8 (WW 8) onwards. The cells which have "1" in them indicate that John is busy.
Now I would like to achieve this (showing when John will be available) by using a formula in Cell B22. For example, if the formula can show somehow "WW8" in cell B22 it would suffice.

I am working on a Property Management spreadsheet to track the availability of vacant units (and upcoming vacant units). I'm trying to write a formula to count the number of current units that are listed as vacant, so that I can ultimately report on the overall unit availability as of any given period (today, 15, 30, 60, 90-days out). All of the data in this spreadsheet is dynamic and each field can change at any time. There are also a lot of blank fields as well. I am using Excel 2003.
Here are the fields/data that I am using for my analysis:
Column A - (Reporting Period Dates): A2 = 5/20/08, A3 = 6/5/08, A4 = 6/20/08, etc.
Column B - (Unit Status: V=Vacant, O=Occupied): B2 = V, B3 = V, B4 = V, B5 = V, B6 = V, B7 = V, B8 = O, B9 = O, B10 = O, B11 = O, B12 = O, B13 = O
Column C - (M/O Date. These dates represent when the current resident will move out) - Cells C2:C13 contain dates for when each tenant will move out
Column D - (M/I Date. These dates represent when the future resident will move in) - Cells D2:D13 contain dates when the future tenant will move in
If my reporting period is 5/20/08 (cell A2), then I need to calculate how many Vacant units (B2:B13) I will have as of 5/20. The formula will need to count all of the current Vacant units (B2:B13), plus it will also have to take into account any Move Outs (C2:C13) during the reporting period. For example, let's say we have an Occupied unit that is scheduled to move out on 5/15/08. The cell will show this as "O" but the formula will need to determine if the M/O date is <= the Reporting Date of 5/20/08 (A2). If so, then Excel would count this unit as a Vacant for the period.
In addition to this, I also need the formula to look at upcoming Move IN dates (D2:D13). The formula will also have to determine if the MI date is <= the Reporting date (A2). If the MI date falls prior to the Reporting Date, then this unit should be considered as Occupied and should NOT be added to the total available units. NOTE - there are quite a few cells in column D that are blank and don't have MI dates. If there isn't a MI date, then the formula should assume that those units are Vacant if it is past the prior tenants MO date.
I'm assuming that Excel can handle multiple conditions like this, however, I am not smart enough to figure it out.

In the sheet I'm currently working on I have a column (column C) that uses a validation so that users can select from a number of call types (data tracking in a call center). I allowed for an "Other" option, with a free-form column (column D) dedicated to the "other" reason in case the list doesn't cover the type, but I'm running into a problem where people use the other column to describe call types already listed. Is there anyway to lock the Other column (column D) unless Other is selected in the drop down in the Call Type column (column C)? The sheet I'm working with contains confidential data so I can't post it, but if this isn't clear enough I can draw up a mock sheet.

Hoping someone might be able to kindly help me out with this one. It's for a spreadsheet of call charges (credit crunch thing).
On the sheet, I have the call charge up to an hour ($H$5). Over an hour, it's charged per minute at the rate in $H$6.
In cell E27 I can enter the number of minutes for the call.
So basically, if E27 is up to a value of 60 then the cost is just H5, if the value in E27 is 61 or more then it's H5 + (E27-60)*H6.
I'm thinking it's an 'IF' but keep making a mess of it...

How do I calculate YTD from 1 MTD cell? The YTD cell needs to keep a running total of the MTD cell. If the current YTD cell has the number 11 in it and I typed 2 in the MTD cell the YTD cell needs to increase by 2.

What I need is to add a field that gives a gross margin percentage for a project.
To begin, I simplified the following data that the Pivot Table is using. Project (10 different projects), Account Number, Account Category (Revenue, and Cost), Debit Amount, Credit Amount, and a manually inserted column named Total (CR Amount - DR Amount). See 1st image. Pivot1.jpg
I have designed the Pivot table so it lays out like this. Pivot2.png Pivot3 (2).png
I have been trying to enter a calculated field that would automatically provide the Gross Margin Percentage. In the 2nd image, the Grand Total is the gross margin, but I am unable to use that as a selection when creating a calculated field.

I am trying to figure out the calculation steps that Goal Seek is doing behind the scenes so I can create the formula rather than clicking on goal seek whenever I need to make a change. I need to maintain certain weeks of supply every week depending on the sales. Let's say i want to maintain 5 weeks of supply every week, I would like to insert a column for "Suggested To Order' column that would change if weeks of supply goes below 5. In this scenario I would do a Goal Seek, but I want to automate the calculation so I don't have to do this step every week.

My understanding of Excel is that the calculations are performed in Column A first and then down through the rows in Column A. After all the calculations are finished in A, the calculation moves over to Column B and down the rows in B. Is this true?
I know that Excel is a little more complicated than that especially when it creates a queue for calculations, etc. However, assuming there's no calculation list/queue, would the above be correct?

I'm creating a spreadsheet to calculate materials with the following columns Cost/10% of Cost/Customer Cost/Qty/Total cost.
I understand that whilst showing rounded to 2 decimal places excel stores more than this in the cell. which then throws out the Total cost by a few pence.
My research leads me to believe I need to use the ROUND function but I'm unsure which cell to use it or how.

I use VBA with the macro recorder. Now I'd like to programming a code to calculate the average of three cells.
I've done a lot of measurements about 180 but it can be also more. For one test object I've always done three measurements to get then an average.
My values are beginning in cell C2:CXXX, D2:Dxxx and E2:Exxx. For example I'd like to get the average from C2:C4, D2:D4 and E2:E4. The result of C2:C4 I'd like to have in cell H2, the result of D2:D4 in cell I2 and the result of E2:E4 in cell J2. Then the next calculation is C5:C7, D5:D7, E5:E7 and the results in H3, I3 and J3. And so on.
I've attached my excel file, maybe I didn't explained it well. The VBA-Code is for sheet Export.

I got a work sheet with 672 columns of information that im trying to cross compare against. I wanna compare each column against every other column in that row. I have 200 rows of data. That means each i need excel to do 226,128 comparion calculations each row. So that means in the entire work sheet its gotta do 91 million comparisons. Im on a dual core 1.8ghz core 2 duo cpu and 2 gigs of ram on xp pro with excel 2007. I even bumped up my virtual memory by 3 times the size it was yet still its taking forever.
Its taking over 3 hours to do this whole page of calculations. So i opened up visual c++ and quickly programmed in the same code with some generic values and within 3 seconds it computed it all. My guess is that the bottle neck is when excel has retrieve data from the cells because other than that i cant figure out why its so slow. Heres a section of my

I need to find out the amount of time between two dates for filling out
funeral benefits. The form asks how long the person has been alive in Years
Months and Days.
I would like to know if I put for instance 10/21/1955 in say A1 as the birth
date and 01/25/2006 in B1 as the date of death. So what is the formula, if
one, to calculate the time in years months and days that has passed between
the two dates?

I am writing a formula to calculate the last and next month end e.g. if I
enter 28-02-06, the expected result will be liked 31-01-06 and 31-03-06.
28-02-06 will be stored in cell A1, and my expected result will be displayed
in A2 & A3.
My formular is liked " =A1-31 , = A1+31. But because of "31"
has to change each month, therefore if doesn't work to my calcaulation.
Also, from the above example, the calculation for March is correct "31-03-06"
but the January is worng, it comes date on 28-01-06. But I need both result
at the end of the month.

I have been burning brain cells trying to figure this out.
I get these numbers from an online source and they come in like this:
A B C D E
1/1/0912:01AM02:40AM11:18AM07:55PM
The times do not come in as times...when I format the cell to time it doesnt change...that is my first problem.
What I would need to do to these times is: take B and C and find what time is in the middle of them and put that in a different column.
This mess will also need to be plotted on a chart with time by the minute for one day as the X axis. In my example I drew lines on the chart to show what I mean....the blue lines I dont want charted...I use those to find the time in the middle.
