No, that's too specific itself. The Rolls Royce factory would fall under categories 1, 2, 3 and 4 of that list - and I woldn't be at all surprised if their engines were also used on ships too - maybe to power motor torpedo boats? In other words, that particular historical factory produced IC that could be used to build any class of unit whateoever.
No it wouldn't if we use a victoria style unit building. Meaning that units cost stuff and use little or no ic to produce, the ic is spent stockpiling the components.
Lets say we have types of factories
Automotive
Airplane
Small arms
Artillery
Shipyards
General
For example an armored division would require, ofcourse, large numbers of automotive parts, say 1 part represents 1 truck and 10 one tank, 15 one heavier tank etc. It would also require sigificant numbers of small arms, artillery and general supplies. All specific requirement values come from the specific unit they are assigned to and are decided by the type of tanks equipped, doctrine, national sliders and tech.
One battleship would require large amounts of steel, would occupy one largeshipyard slot (which should be rare enough), 1-2 aircraft, rather large amounts of artillery as large caliber guns were not cheap and easy to produce and large amounts of general supplies.
An aircraft unit uses large amounts of aircraft, the heavier and bigger the aircraft the bigger the aircraft costs. Fighters units, for example cost 100, tac bombers 200, strat bombers 400. Also large amounts of general goods. Tiny amounts of small arms.
Constructing AA consumes large amounts of artillery and some general goods. Forts use up a lot of general goods and some artillery.
All units naturally have MP cost
So to simulate the production for rolls royce you can have five different types of rolls-royce owned plants with no problem.
You get the point I hope. This might be too much micromanagement perhaps, but this is what i would like to see in the end.
