Constructor Details

TransitionTimes

public TransitionTimes(CPSeqVar seqVar,
 CPIntVar[] time,
 int[][] dist)

Links visits of nodes within a CPSeqVar to given time windows CPIntVar. The nodes belonging to the sequence must be visited during their time window. The triangular inequality must be satisfied.

Parameters:

seqVar - sequence visiting the nodes

time - time windows of the nodes

dist - distance matrix between the nodes

TransitionTimes

public TransitionTimes(CPSeqVar seqVar,
 CPIntVar[] time,
 int[][] dist,
 int[] serviceTime)

Links visits of nodes within a CPSeqVar to given time windows CPIntVar. The nodes belonging to the sequence must be visited during their time window. The triangular inequality must be satisfied.

Parameters:

seqVar - sequence visiting the nodes

time - time windows of the nodes

dist - distance matrix between the nodes

serviceTime - processing time of each node

TransitionTimes

public TransitionTimes(CPSeqVar seqVar,
 CPIntVar[] time,
 int[][] dist,
 Optional<int[]> serviceTime)

Parameters:

seqVar - sequence visiting the nodes

time - time windows of the nodes

dist - distance matrix between the nodes

serviceTime - processing time of each node
