dockyards

how about something like this:
A dockyard bay is like a hangar bay, but can also do bigger repairs and
servicing.  The size of the bay is the total mass of ships it can
accommodate.  To actually service ships, servicing facilities must be
provided: 

The mass depends on the number and size of ships which can be worked on
simultaneously.
	   Escort/Merchant    Cruiser	      Capital	    Supership
Servicing    1 per hull      2 per hull     4 per hull	    8 per hull
Repairing    2 per hull      4 per hull     8 per hull	   16 per hull
Building     4 per hull      8 per hull    16 per hull	   32 per hull
Cost eg 5 points per 1 mass

so a mass 100 dockyard bay with 16 mass of services could build 1
capital,
or 2 cruisers, or 4 escorts, or could repair 2 capitals, or service 4
cruisers while repairing 4 escorts, etc.

Hulls that won't fit in the dockyard bay (as they're too big, or because
it's too full) need double the mass of services (or increase the time
pro
rata) to get the same job done due to the inconvenience of using
shuttles
and workers in vacuum etc., so the bay above could service 1 supership
at
the normal speed, repair it at half speed or build it at one quarter
speed.
