Scheduling in an M/G/1 Queue
Poisson arrivals with rate .
Service requirements are i.i.d. with distribution F(x)=P[X x].
Complementary cumulative distribution denoted by
Attained service is known (total service requirement unknown)
Optimality criterion: Mean number of jobs in the system
( ) )x(F1xF -=
Two important set of disciplines depending on whether the
size of jobs is known.
The size is known: Shortest-Remaining-Processing-Time
