Class VariableReleaseDatesSchedulingComputer

java.lang.Object

ai.libs.jaicore.problems.scheduling.ASchedulingComputer

ai.libs.jaicore.problems.scheduling.computers.VariableReleaseDatesSchedulingComputer

All Implemented Interfaces:

IScheduleComputer

public class VariableReleaseDatesSchedulingComputer
extends ASchedulingComputer

The unique aspect of this computer is that Job release dates are ignored. Instead, release dates are automatically derived from the assignments and the latest arrival date: The release date is set to the minimum of the processing time and the latest allowed arrival time.
