public class NoOverlapBinaryWithTransitionTime
extends AbstractCPConstraint

Binary NoOverlap constraint with transition times enforcing that two interval variables A and B do not overlap and respect minimum setup/transition times transitionTimeAB (when A precedes B) and transitionTimeBA (when B precedes A) when both are present.

Constructor Details

NoOverlapBinaryWithTransitionTime

public NoOverlapBinaryWithTransitionTime(CPIntervalVar A,
 CPIntervalVar B,
 int transitionTimeAB,
 int transitionTimeBA)

Creates a binary non-overlapping constraint with transition times between A and B.

Parameters:

A - the first interval variable

B - the second interval variable

transitionTimeAB - the minimum transition time when A precedes B

transitionTimeBA - the minimum transition time when B precedes A

NoOverlapBinaryWithTransitionTime

public NoOverlapBinaryWithTransitionTime(CPBoolVar AprecedesB,
 CPIntervalVar A,
 CPIntervalVar B,
 int transitionTimeAB,
 int transitionTimeBA)

Creates a binary non-overlapping constraint with transition times between A and B, channeled with a given precedence boolean variable AprecedesB.

Parameters:

AprecedesB - a boolean variable that is true iff A precedes B

A - the first interval variable

B - the second interval variable

transitionTimeAB - the minimum transition time when A precedes B

transitionTimeBA - the minimum transition time when B precedes A
