Just give the AIs a "rubber stamp" mode.

If its in "Rubber Stamp" it assumes it can do whatever it wants, otherwise you do the paperwork manually:
"Alpha Fleet Needs supplies! Should we:
a) Resupply now
b) Wait ___ Turns before asking me again."

in a series of message boxes at the beginning of turn.

You can either let the AI do what it wants, or decide whether each thing it wants is good, but still let it do the "dirty work" of checking supplies/finding/moving the ships. The third option is to turn off the AI and do it all yourself.
