public class IFTMinusUIT
extends PR

This class implements a rule developed by Branke and Pickardt (2011) for job shop problems, which attempts to measure the usable idle time on other work centers in the prioritization of jobs.

The lookahead needs to be enabled in the simulation for this rule to work properly.
