Same Location Constraint

Hi @power1990,

You can apply a hard route constraint to force a group of jobs to be in the same route. See the following posts:

Job relations in same route not working for multiple jobs using hard constraints

I have 4 jobs and all jobs must be done in same route. I cant use soft activity as I am not sure how much penalty/rewards will be useful for that. I have used below objective function: stateManager.addStateUpdater(new UpdateJobRouteAssignment(stateManager)); HardActivityConstraint sameRouteServicesConstraint = new HardActivityConstraint() { @Override public ConstraintsStatus fulfilled(JobInsertionContext iFacts, TourActivity prevAct, TourActivity newAc…

How can I ensure that services occur in the same route using constraints?

I’m trying to use Jsprit constraints to ensure that a solution route has a specific set of services… Given the services [S1, S2, S3, ..., S10], I want to ensure that services [S2, S4, S6] occur in the same route… For this, I am using HardRouteConstraint… @Override public boolean fulfilled(JobInsertionContext context) { // jobIds = [S2, S4, S6] Job thisJob = context.getJob(); if (jobIds.contains(thisJob.getId())) { for (String jobId : jobIds) { VehicleRoute route = stateManager.get…

Best regards,
