A new contingent critical-ratio technique

Critical-ratio technique is a common approach used to identify the next job to run on a machine. Recently, an alternative procedure, known as the contingent critical-ratio technique, has been proposed and proved to be superior to the conventional critical-ratio rule. Examines the logic of the contingent critical-ratio techique and proposes a new procedure. Experimental results show that the new procedure performs better than both the contingent critical ratio and conventional critical-ratio techniques.
