public class NAClosestFacilitySolver
extends Object
implements com.esri.arcgis.interop.RemoteObjRef, INASolver, INASolverSettings, INASolverSettings2, INAClosestFacilitySolver, IPersistStream, ISupportErrorInfo, Externalizable

Performs closest facility analysis.

Remarks

NAClosestFacilitySolver is a Network Analyst solver that finds a set of closest facilities from a set of incidents. It can find the closest facility based on any suitable cost attribute and then write the results to an in-memory feature class. It has options to limit the number of facilities to compute to/from any incident by either specifying a maximum number of facilities to find or by specifying a cutoff value. For example, find the three closest facilities from a set of incidents that are no more than 10 Km away. It can also generate the actual path or straight line geometries connecting each facility to each incident. The NAClosestFacilitySolver honors all of the settings of the INASolverSettings interface.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.
