WHATS NEW
|
|
==========
|
|
**v1.4.0** ? in preparation
|
|
|
|
<b> SKILLS </b>
|
|
|
|
Skills can now be included easily (see for example https://github.com/jsprit/jsprit/blob/master/jsprit-examples/src/main/java/jsprit/examples/SolomonWithSkillsExample.java).
|
|
It lets you assign hard requirements to jobs and vehicles/drivers. For example, a technician requires a screwdriver to serve customer A or
|
|
your vehicle requires a loading bridge to unload freight at customer B etc.. You can add an arbitrary number of skills to jobs and vehicles.
|
|
|
|
To enable the algorithm to consider skills, you need to use <code>core.algorithm.VehicleRoutingAlgorithmBuilder</code> as follows:
|
|
|
|
<pre><code>
|
|
VehicleRoutingAlgorithmBuilder vraBuilder = new VehicleRoutingAlgorithmBuilder(skillProblem,yourConfig);
|
|
vraBuilder.addCoreConstraints();
|
|
vraBuilder.addDefaultCostCalculators();
|
|
|
|
StateManager stateManager = new StateManager(skillProblem);
|
|
stateManager.updateSkillStates();
|
|
|
|
ConstraintManager constraintManager = new ConstraintManager(skillProblem,stateManager);
|
|
constraintManager.addSkillsConstraint();
|
|
|
|
VehicleRoutingAlgorithm vra = vraBuilder.build();
|
|
</code></pre>
|
|
|

|
<b> UNASSIGNED JOB LIST</b>
|
|
|
|
- new feature: unassigned job list
|
|
|
|
<b> STATEMANAGER </b>
|
|
|
|
- StateFactory.createId(String name) moved to core.algorithm.state.StateManager.createStateId(String name)
|
|
- StateFactory moved from core.problem.solution.route.state.StateFactory to core.algorithm.state.InternalStates
|
|
- StateId moved from core.problem.route.state.StateFactory.StateId to core.algorithm.state.StateId
|
|
- StateFactory.createId(String name) is not accessible anymore
|
|
- constructor new StateManager(VehicleRoutingTransportCosts costs) does not exist anymore, but is new StateManager(VehicleRoutingProblem vrp)
|
|
- StateManager.addDefault... methods do not exists anymore. Client must now decide what to do when state does not exist.
|
|
- deprecated core.problem.VehicleRoutingProblem.Builder.addVehicle(Vehicle v) and added core.problem.VehicleRoutingProblem.Builder.addVehicle(AbstractVehicle v)
|
|
- deprecated core.problem.VehicleRoutingProblem.Builder.addJob(Job j) and added core.problem.VehicleRoutingProblem.Builder.addJob(AbstractJob j)
|
|
|
|
<b> LOGGER </b>
|
|
- migrated from log4j1x to log4j2
|
