Simple Rules

FIFO (first in first out) PNj = taj

SPT (shortest processing time) PNj = oj

ODD (earliest operation due dates) PNj = tdj

EDD (earliest job due date) PNj = tdj *

SL (slack) PNj = tdj* - t - wj* * = tsj *

CR (critical ratio) PNj = (tdj - t) / (tdj - tdj - oj)

SL/OPN (slack per remaining operation) PNj = tsj / nj*

SL/RPT (slack/remaining processing time) PNj = tsj / wj*
