Formula To Work Out Maintenance In Life Cycle Model
Jul 4, 2014
I'm try to do a what IF Formula, so I can automatically add the cost into the right year for a lifecycle cost
My criteria is in column K I have either New Build or Existing and column AT I have year 12 of the lifecycle and column AZ I have year 18
And what I want the result to say is IF Column K Say New build I want the value of the first maintenance year to start in year 18 and column k say Existing I want the value of fist year Maintenance to start in Year 12
I already have this formula in the Column AT&AZ working out he value
IF(ISERROR(MROUND((AQ$1-$Q2),$P2)),"0",
IF((MROUND((AQ$1-$Q2),$P2)+$Q2) = AQ$1,$AF2,"0"))

I am trying to create a life-cycle management sheet that is simple for the user but gives specific data.
The user would input "Date", "Machine type", "Component Set No.", and "Component". This would happen over a period of time and build up a picture of how often each component was lasting and it's average life in days.
I am fine from the user input side but am struggling to figure out how to extract ONLY the data I need to display in a graph.
For example: If I want to see the average no. of days "component X" is lasting before being replaced I've not been able to extract just that data. I have tried using a pivot chart but this won't do exactly what I'm after.
See the attached for a clear explanation : Component LifeCycle Example.xlsx

I am trying to figure out a formula to calculate remaining useful life. I have the following information:
In Service Date (Cell W2)
Estimated Life (Cell X2)
Aquired Value (Cell Z2)
Is there a formula that will just calculate how much life is left based on the information i have?

I price life insurance policies and need a formalu for the following new Fund:
If the sum of the first two years of premium added to 10% of that total is equal to or less than 25% of the face amount, the case fits into the general parameter.
Here is what I have, but it isn't working:
=IF((U2+V2)*10%)+(U2+V2))

I have some Excel models out in the field with some old VBA code that is now causing problems. I regularly develop 'patch' models to make updates or repairs to user models, but need the VBA code syntax to get into a Worksheet module and change one line of VBA code.
The worksheet is named 'Forecast' and I need to change line 5 of my VBA code.
The vast majority of my users are on Excel 2000. I remember the security issues with newer Excel versions and can walk then through that, but I forgot the code syntax I need to get the job done.

I am trying setup a maintenance schedule checklist for a large list of items. Each item has a cycle in weeks for the checklist. I set up a nested if statement to check if the item is overdue or done based on the cycle and the current date. The if statement checks when the last time the item was done or overdue and populates an "X" for the next due date. It works fine as long as the cycle is 4 or less. After that there are too many if statements and I get an error. I'd rather not have to use a macro to get this to work. Any ideas?

I have a deferred revenue model. Revenue from each month earns out at an equal rate over twelve months. Sales for each month are in column B (B21) and C. I created formulas for the first year but when I get to the second year, I'm not sure what to do, because the earned premium will include values from previous year sales and current year sales.

We are trying to work out a pricing model based on how many units we will produce. In production the price per unit will be really high when you produce a low quanity, and the price per unit will be lower with the more units you produce (but never reach zero). What we are trying to accomplish is to create a formula to build a pricing structure that accounts for this curve without having to price every possible scenario.
For example, if we have the following data where for 1 unit we charge $3 per unit to produce, for 5 units we charge $2 per units to produce, etc...:
1 units @ $3 per unit
5 units @ $2 per unit
10 units @ $1 per unit
What I need to figure out is how much it would cost per unit if we were to produce 3 units. I'm guessing it would be somewhere around the $2.40 mark give or take. Or say 8 units, would be something like $1.50 per unit.
Is there a formula that can calculate this? I've tried thinking of it as a moving average, or prorating the pricing.

I'm struggling to include a repeating 8 (or 4) weekly cycle in my sheet.
For instance, week 21 starts on 20-05-2013, than I would like to have the below cells filled untill 26-05-2013, following cells must be blank, untill 8 weeks are over, and the first date you see again is 15-07-2013, and so on. Using the MOD formula, I can get the first day of each cycle correctly, but I'm having difficult to get the next 6 cells entered and the next ones blank again untill 15-07-2013
I'm using now following formula, where B is the date:
Code:
=IF(MOD($B$264-B264;56)=0;B264;"")
but I need to nest another IF I guess that takes care of the rest.

i need to work out a formula for my spreadsheet which I use to work out cutting lists for timber frames. I need it to work out if the width of a job is for eg 2400mm i need to work out how many timber studs I need so the space between each stud is between 400mm and 500mm and this will need to work for a range of different sizes of frames. I have it written at the moment and it just devides the width by 400 and gives me a amount of studs but it would work much better if it could space them between 400 & 500.

I'm working on a spreadsheet to compile and print checks. All the check information except the date and first check number is contained in a Wins sheet. I also have a Checks sheet which contains a master check. I used text boxes on the master check to contain individual check information. Each text box is filled in from the Wins sheet by means of formulas. The problem I'm having is how to modify the formula entries in the following code to cycle or loop through all checks required. A sample spreadsheet is attached.

I m trying to write a formula for my financial model. If anyone can take a stab at a solution. I'm trying to write a formula that will equally distribute revenue either over the next 1 month, 2 month or 3 month period depending on size of the deal.
Details:
Sales will fit in 1 of 3 categories. Less than 25k; between 25k & 100k; greater than 100k.
- if under $25K, recognize in next month (month N+ 1)
- $25K-100K, recognize in two equal parts in months N + 1 and N + 2
- over $100K, recognize in three equal parts over 3 months
N + 1, N + 2, N + 3 ...

I'm currently developing a model for a payment schedule. For example, lets say a customer purchases an item from a store, but the store receives that payment in the following month. I'm looking to develop a dynamic model so that if I change the assumption from 1 month to another term (2,3,4+ months etc.) the model will adjust accordingly.
I've started with a formula
=IF(MONTH(H3)-MONTH(G3)=B14,G11*B13)
But of course this will not work once the term is set to larger than 1 month. With B14 representing 1 month, and G11*B13 being payment information (price * quantity).

1. In column A, I have models, in column B, I want to place either a "printer" if the model begins with Phaser or Laser, and if it begins with WorkCentre make it MFD. Also, if the Phaser has MFP on the end, make this an "MFD" and If Color 560 or Docucolor, make this "Out of Scope". How do I read the first part of the string in column A to do this, or do I need to make a second column with this Phaser and WorkCentre broken out?
I have this code attached, but only works if I have the word Phaser or WorkCentre.

I am having a very difficult time determining how to get started with this problem in VBA. I am not sure how to generate the failures, or start the array. I have been racking my brain for quite some time. Company B makes a product that has two component parts. The results of reliability testing for each component shows that the components fail according to an exponential distribution with the following mean time between failure (mtbf).
ComponentMTBF(months)
115
224
Below are Company B's sales records for the past 36 months.

This IF formula does not work on the last part of this formula
IF(E10>50,"$50.00",0)))) and I think there is a conflict with the
IF(E9>199,(E9*0.01) but I cannot figure out what the problem is.
=IF(E8>0,"$0.00",IF(E9199,(E9*0.01),IF(E10>50,"$50.00",0))))

See the attached workbook.
Please edit the formula in column B so that it only gives a BINGO if the adjacent cell in column G is less than 51.
So cell M16 should not be a BINGO because cell G16 is not less than 51.

Combing these two formulas. I have a work schedule spreadsheet. If the employee is Off I want the value to = 0 (zero hours). But if the cell has a start time I need it to calculate those hours. I know both of the formulas work individually. But I need them to work together.
Formula for when cell says OFF:
=IF(C11="Off",0)
And the second
Formula to calculate hours (based on start time/finish time is the same for all employees)
=($X$4-C11+($X$4<C11))*24

=SUMPRODUCT(--($C$1:$C$17="S"),--($C$2:$C$18"S"))
how does this formula work?
It counts the number of instances in a list but not sure how
does the ranges have to be differant for this to work? ie C1:C17 C2:C18

I need to work out a formula which will work out 48 permutations.
There are three headings: Impact, Probability, Risk Category:
ImpactProbabilityRisk Category
VHM = 1
VHH = 1
VHVH = 1
HH = 1
HVH = 1
VHL = 2
HM = 2
MH = 2
MVH = 2
HL = 3
LVH = 3
MM = 4
LH = 4
ML = 5
LL = 5
LM = 5
The formula I need is: if Impact is "L" and probability is "M", then return answer = "5".
The thing is - there are 48 possible answers - and im not sure what formula you could type into 1 cell - which would answer this.

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've recorded a Macro that goes through multiple spreadsheets and refreshes the pivot tables in the sheets. I would like the Macro to run without it actually showing it go to each sheet and showing the pivot table updating. Bascially I would like the spreadsheet to remain on the first sheet while it's working with all the spreadsheet in the workbook when the macro is running.

I have a table, 2 columns by 10 rows (A1:B10). The table values are the result of calculations (imagine they are random). These calculations are performed repetitively for some specified number of repetitions (let's say 10 iterations). (e.g. all of the table values change with each iteration until the 10 iterations are complete. With each iteration all of the values in the table change). At the completion of the 10 iterations (one full cycle) I want to know the minimum and maximum calculate value as the 10 iteration cycle was performed.
To simplify; the table changes 10 times in one cycle. I want to know the minimum and maximum values attained in the cycle.
It is easy to determine the minimum and maximum values of the table for each iteration. It seems the problem would be write some vba code that 1) found the min. and max. 2) save that value 3) find the min and max in the next iteration and compare the old and new values 4) retain the value or replace the min and max values with new values and 5) proceed to the next iteration until the cycle is complete.

So I have a cycle time formula; Start Date to Completion Date, if the task is not complete the completion date field is blank. In this case the cycle time is listed as a negative 5 digit value. The networkdays formula takes into consideration weekends and holidays.How can this field be left blank rather than the negative value?
=NETWORKDAYS(I2,P2,Sheet3!$A$2:$A$10)
