Are there any models for planning aircraft placement in hangars?
I’ve not heard of software programs to do this, but the Navy has made use of a relatively low tech solution to address this problem for decades aboard their aircraft carriers.



Known simply as the Ouija Board, the aircraft handler and his crew utilize a scaled physical map of both the carrier flight deck and hangar deck along with appropriately scaled footprint models of aircraft in order to track and plan aircraft movements.

I’d guess a similar scheme could be employed to solve your problems.
