ArcObjects Library Reference (NetworkAnalyst)

NAVRPSolver CoClass

Performs VRP network analysis.

Product Availability

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

Description

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

Interfaces	Description
IClone (esriSystem)	Provides access to members that control cloning of objects.
INASolver	Provides access to the common interface for all network solvers.
INASolverForwardStar	Creates a network dataset forward star which honors the current solver settings as well as any barriers.
INASolverOutputGeneralization	Provides access to generalization parameters used on solver output.
INASolverSettings	Provides access to settings common to all solvers.
INASolverSettings2	Provides access to settings common to all solvers.
INASolverSettings3	Provides access to settings common to all solvers.
INAVRPSolver	Provides access to the VRP solver.
IPersist	Defines the single method GetClassID, which is designed to supply the CLSID of an object that can be stored persistently in the system. IPersist is the base interface for three other interfaces: IPersistStorage, IPersistStream, and IPersistFile.
IPersistStream (esriSystem)
ISupportErrorInfo	Indicates whether a specific interface can return Automation error objects.
IXMLSerialize (esriSystem)	Provides access to members that XML serialize and deserialize an object to/from XML.

Remarks

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.
