Pre-emptive scheduling is scheduling where a task is not atomic ; you 
can stop it in the middle, do something else then restart it (at not 
additional cost). It is easier than non pre-emptive scheduling.

If you want to deal seriously with scheduling and constraints I suggest 
you have a look at the work of Philippe Baptiste 
http://www.lix.polytechnique.fr/~baptiste/ 
and more specifically his book "Constraint based scheduling" (with C. Le 
Pape and W. Nuijten)
