Model B describes perfect coordination. The fabrication crew
and the installation crew plan before starting their work and
decide on the sequence in which to draw resources. Cutsheets
and areas are assigned sequence numbers so they can be drawn
in FIFO order (STROBOSCOPE's default discipline). CutSheets
1 through 40 will go to fabrication before 41 through 80, and so
on. Similarly, Area 1's prerequisite work will be performed prior
to Area 2's, and so on.
