Shortest job next

Shortest job next is advantageous because of its simplicity and because it minimizes the average amount of time each process has to wait until its execution is complete.

Highest response ratio next is similar but provides a solution to this problem using a technique called aging.

[3] Multilevel feedback queue can also be used to approximate SJN without the need for the total execution time oracle.

[1] Shortest job next can be effectively used with interactive processes which generally follow a pattern of alternating between waiting for a command and executing it.

[4] Value-flow rate (VFR) is an alternate, more intuitive name given to WSJF which expresses cost of delay and duration using unitless relative "points" rather than actual units of time or money.
