Simple Rules

FIFO (first in first out) PN_j = t_aj

SPT (shortest processing time) PN_j = o_j

ODD (earliest operation due dates) PN_j = t_dj

EDD (earliest job due date) PN_j= t_dj *

SL (slack) PN_j = t_dj* - t - w_j* * = t_sj *

CR (critical ratio) PN_j = (t_dj - t) / (t_dj - t_dj - o_j)

SL/OPN (slack per remaining operation) PN_j = t_sj / n_j*

SL/RPT (slack/remaining processing time) PN_j = t_sj / w_j*
