Remarks

The values within this enumeration are used to populate information on constraint violations involving orders and routes within a VRP problem instance. These values are stored in the ViolatedConstraints fields on the Orders and Routes NAClasses within a VRP NAContext.

ViolatedConstraints field values on the Orders and Routes NAClasses identify all constraint violations associated with a given order or route feature, respectively, by specifying a combination of bits defined in esriNAViolatedConstraints.

The valid values for this field are 1 - 16383. Each bit represents one of the enumeration settings in esriNAViolatedConstraints.

esriNAViolationMaxOrderCount - this value indicates a violation of a route's MaxOrderCount property
esriNAViolationCapacities - this value indicates a violation of a route's Capacities property
esriNAViolationMaxTotalTime - this value indicates a violation of a route's MaxTotalTime property
esriNAViolationMaxTotalTravelTime - this value indicates a violation of a route's MaxTotalTravelTime property
esriNAViolationMaxTotalDistance - this value indicates a violation of a route's MaxTotalDistance property
esriNAViolationHardTimeWindow - this value indicates a hard time window violation on an order, depot, or break
esriNAViolationSpecialties - this value indicates that the specialties required by an order were not found on the target route(s)
esriNAViolationZone - this value indicates that an order does not fall within a hard route zone
esriNAViolationOrderPairMaxTransitTime - this value indicates that an order belongs to an order pair and violates the pair's MaxTransitTime property
esriNAViolationOrderPairOther - this value indicates that an order belongs to an order pair and is unrouted because the other order has some violation
esriNAViolationUnreachable - this value indicates there is an unreachable depot or other order from a particular start depot or order
esriNAViolationBreakRequired - this value indicates there is a break assigned to a route which cannot be added to the route without introducing violations
esriNAViolationRenewalRequired - this value indicates there is a route renewal assigned to a route with capacity violations which cannot be added to the route without introducing violations
esriNAViolationBreakMaxTravelTime - this value indicates there is a violation of a break's MaxTravelTimeBetweenBreaks property

Thus, for example, if an order feature was unable to be routed because it violated all available route capacities and also violated all available route zones, then the ViolatedConstraints field value for that order feature would be esriNAViolationCapacities + esriNAViolationZone (i.e., 2 + 128), which would equal 130.
