Question on daily maint...

[Commander Truestar]

Hi All,

So I had a spreadsheet I made *mumble* years back and it got blasted in a drive event..

And I was pulling out my books to recreate the spreadsheet and stopped to consider the work I had gone through. Then I thought, there must be a fairly simple formula for determining how many daily man hours are required for ship maint..

So can anyone suggest a good and simple formula for determining this?

I really do not want to spend more hours with my MT Ref's Manual

Thanks!
Marc

multiply the unrounded crew formulae by 40/7

 

[Commander Truestar]

so: ((H+A)/C/400)*(40/7)

Where:
- H = Hull CP
- A = Hull Displacement /100
- C = Computer CP Multiple

Yup. Do same for electronics and engineers...

Thanks!
Ironically, I found my notes and am posting them as follows:

Routine Daily Maintenance

Starships require daily maintenance.
This requirement - expressed in man hours - is given by:
....Man hours = Cp/Cm/100*Tv*
......Where:
........Cp=Total Control points (See the formula below the table * )
........Cm=computer Cp multiple (See Table 3, MT Referee's Manual Pg 81)
........Tv=TL variable (See the table below)
........x=Vessel age variable (See the table below)

Years since...........Maintenance.....Annual Maint. cost..................TL
construction/refit.....variable (x)....% of Purchase price.....TL......Variable(Tv)
.....0-10.....................1.....................0.1...................7-A........1.5
....11-20...................1.2....................0.1...................B-C........1.3
....21-40...................1.5....................0.1...................D-E........1.1
....41-60...................1.9....................0.2...................F-G........ 1
....61-100.................2.4....................0.3.....................H+........0.9
..101-200..................2.9....................0.4
.....200+...................3.5....................0.5

Modified Table 2, MT Referee's Manual Pg 81
Total CP = ((Vessel Cost/100,000)*Vessel Tech Level)
* NOTE: I noted you'd eventually add all the CP per ship section to get the ship's total
CP. So I just did the add in costs and found the total CP based on total cost.

Not all cremen perform maintenance tasks. Bridge crew reasonably don't, nor maneuver crew. (except on small ships.)

Maint and Engr definitely do, as do electronics crew.

What?! Bridge & Maneuver crew do no maintenance? Then what are they doing when the XO calls ot on the 1MC "Sweepers, sweepers man your brooms. Give the ship a clean sweep down fore & aft. Sweep down all lower decks ladder wells and passageways. Now, Sweepers!"

[aramis]

Sweepers are maint crew by the definitions given. The Maneuver crew are the officers... specificallly equivalent to the dive officer and nav officer.

Just because the USN puts ratings on the bridge doesn't mean the 3I will.

I like this table; however I think it'd be appropriate to increase the cost for the first 20 years or so, as newer parts are more pricey and less available, decrease it through the 21-100 (for ships that are common) and then increase it sharply after that point (as obsolescent ships and parts are retired / no longer manufactured.)

Sorry for the delay...
This chart was right out of the book

Well it said "Modified Table 2, MT Referee's Manual Pg 81"

So I wasn't sure what was modified. I don't own MT at all, so i've never seen it =]
