NAVRPSolver CoClass

Performs VRP network analysis.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server. Requires Network Analyst Extension.


This object is new at ArcGIS 9.3.

Extended Error Information

Use the ISupportErrorInfo method InterfaceSupportsErrorInfo to determine if the object supports extended error information. If the object supports extended error info, VC++ developers should use the OLE/COM IErrorInfo interface to access the ErrorInfo object. Visual Basic developers should use the global error object Err to retrieve this extended error information.


Interfaces Description
INASolver Provides access to the common interface for all network solvers.
INASolverSettings Provides access to settings common to all solvers.
INASolverSettings2 Provides access to settings common to all solvers.
INAVRPSolver Provides access to the VRP solver.
IPersistStream (esriSystem)
ISupportErrorInfo Indicates whether a specific interface can return Automation error objects.


NAVRPSolver is a Network Analyst solver that computes an optimized set of routes for a fleet of vehicles to service a set of input orders. The NAVRPSolver can also honor time windows, multiple route capacities, travel duration constraints, route zone and route seed point constraints, specialties constraints, and paired order constraints. The NAVRPSolver honors all of the settings of the INASolverSettings interface except for IgnoreInvalidLocations. If invalid locations are present, the solver will return an invalid input error, along with the appropriate GP messages identifying each error.
