some short feedback:

• SequenceOptimization API is restricted to a planning horizon of 24 hours - so if you want to compute a driver's whole week in one go, this would technically require a switch to RouteOptimization API.

Hello Ignacio, well - any optimization algorithm tries to minimize/maximize a target function. While OPTIFLOW and xServer 2.29 "Monetary" use values such as vehicle cost per kilometer driver cost per hour ... the old school xTour2 uses abstract values you can hardly influence through the A...

Hello Mehdi,

please look into the Sequence Optimization API and consider the known restrictions:

• max. planning horizon = 24 hours

As an alternative you can consider the
Route Optimization Optiflow API.

Please check this thread " Tour Optimization a la PTV (driven by xTour2) " It describes the generic approach towards "optimization in xTour2" which uses some abstract internal cost function in the traditional mode. Since the acquisition of OPTIFLOW - which is 100% based on real c...

just to be complete:

• v2.27 : monetary cost optimization in xTour was available as experimental feature
• v2.28 : monetary cost optimization in xTour was available as released
• v2.29 : monetary cost optimization in xTour was still available but announced to be discopntinued with v2.30

I made further tests:
The attached Gantt shows

• The two tours I created successfully with a first run and TWO vehicles without break intervals.
• Then I evaluated the output plan but also applied the break rules for one of the vehicles
• This led to an invalid input plan as expected.

That was a tricky one... For some reason all but one driver have break rules. Drivers.png In this case the services (each last 3 hours) are not possible within the given constraints (opening times of the location, driving time from/to depot...) So this is why one order is scheduled and the other one...

Hi Ignacio, a distance matrix can be seen as a storage of some KPIs of undeerlying AB-routes with equal routing options: The primary key of the storage is the combination of the route locations of start and destination. The stored data contains traveltime distance violation state direct distance sta...

Hi there, as a watcher in this forum you are probably familiar with the story behind loading space optimization and you know pictures such as this one: loadingspace.png Now this time I have a question to you: How do drivers in reality pick the freight into the containers / bins? Do they use tools su...
