Benchmark dispatching rules.
RulesDescriptions
RR Raghu and Rajendran 
COVERT (weighted) cost over time 
ATC (weighted) apparent tardiness cost 
PT + WINQ + NPT + WSL PT + WINQ plus NPT and waiting slack* 
PT + WINQ + SL processing time plus WINQ and slack 
2PT + WINQ + NPT double processing time plus WINQ and NPT 
SPT + PW + FDD shortest processing time + PW plus earliest flow due date** 
Slack/OPN slack per remaining operations 
Slack slack 
FIFO first in first out 
EDD earliest due date 
CR critical ratio 
CR + SPT critical ratio plus processing time 
WSPT weighted shortest processing time 
LWKR least work remaining

*PT is the processing time, WINQ is the work in next queue, and NPT is the next processing time.

**PW is the process waiting time.
