The two things that occur to me are:
1) Using a spreadsheet (like Openoffice.org's Calc, and there, we're
back on-topic :) to create a trivial "bitmap" of sleep/wake times.
Column A is hours 1-72, columns B-? are crew names. There's an S or W,
or just an X, or whatever, in the cell as needed. Or S = sleep for
whole hour, s = sleep for half an hour, or whatever. Or up to four 'X'
for 15-min increments. Or...or...or...
2) Using some (F/OSS :) project management software set up so that the
dependencies and critical path makes sense. I know very little about PM
software, so this idea may be infeasible, but it's something that is
geared to charting time periods...
The more I think about this, the more I think some kind of visual
"bitmap" is going to be the way to go.
But I also kind of think you must be re-inventing the wheel. The FAA &
NTSB must already have some standard way to do this. Probably any
accident investigation type organization does. And there must be some
books. OK, here we go:

Lots of stuff on the shuttle, but also a book:

That last one looks like the--ummm--ticket... And the "Searches related
to: accident investigation timeline" at the bottom of the Google page
look good too.

"Microsoft Tax" = the additional hardware & yearly fees for the add-on
software required to protect Windows from its own poorly designed and
implemented self, while the overhead incidentally flattens Moore's Law.
