General

Once Network Analysis is enabled, on the Service Editor dialog box, you can click on Network Analysis and specify the below general settings.

• Output Directory—The location to which result layers are written.

• Default Output Geometry Precision—This value sets the default precision of the output geometry after generalization. If it is set to zero or not specified, no generalization of output geometry is performed. If it is specified and positive, it represents the MaximumAllowableOffset parameter. Generalization is performed according to IPolycurve.Generalize.

• Allow users to save result layers on the server—This box specifies whether users can save result layers on the server for future reuse.

• Save result layer on server when an error occurs—This box specifies whether result layers should automatically be saved in the output directory if there is an error during analysis. If selected, this option may aid in troubleshooting an error.

• Save result layer on server when debugging—When this box is selected, result layers will automatically be saved in the output directory for every request if the log level is set to DEBUG.

• Ignore network location fields—This setting tells the service to not use the location fields on the input analysis locations (stops, barriers, facilities, incidents, and so on) if they are passed in with the request. It is useful to ignore network location fields if street names change often, to avoid passing in requests with stale location fields.

Constraints

Constraints are a set of properties that can be defined for each solver to set parameters for your service output. These properties can be set from the Constraints tab. Common to each solver are the following constraints:

• Max Barriers—The maximum number of point barriers allowed to pass in per request.
• Max Features intersecting line barriers—The maximum number of streets that can be restricted by line barriers per request.
• Max Features intersecting polygon barriers—The maximum number of streets that can be restricted by polygon barriers per request.
• Force Hierarchy Beyond (Extent of Inputs) and Units of Force Hierarchy Beyond (Extent of Inputs)—When stops are a great distance apart, solving requests can require a lot of time and server resources if this option is not selected.

Each solver has additional constraints that can be set:

Route

• Max Stops—The maximum number of stops that the user is allowed to pass in per request.
• Allow time windows—This option specifies whether the service supports the user passing in time windows on the input stops.

Service Area

• Max Facilities—The maximum number of facilities allowed to pass in per request.
• Max Break and Units of Max Break—The maximum break value that may be specified for a service area request. The impedance units can be based on the following:
  • Time
  • Length
  • Other
• Force Hierarchy Beyond (Break) and Units of Force Hierarchy Beyond Break—The maximum break value that may be specified for a service area request. After this maximum, the server will automatically change the request to use the network hierarchy.

Closest Facility

• Max Facilities—The maximum number of facilities allowed to pass in per request.
• Max Facilities to find—The maximum number of facilities from an incident you want the service to be able to find per request.
• Max Incidents–The maximum number of incidents allowed to pass in per request.

OD Cost Matrix

• Max Destinations—The maximum number of destinations allowed to pass in per request.
• Max Destinations to Find—The maximum number of destinations from an origin you want the service to be able to find per request.
• Max Origins—The maximum number of origins allowed to pass in per request.

Vehicle Routing Problem

• Max Orders—The maximum number of orders allowed to pass in per request.
• Max Routes—The maximum number of routes allowed to pass in per request.

Location Allocation

• Max Demand Points—The maximum number of demand points allowed to pass in per request.
• Max Facilities—The maximum number of facilities allowed to pass in per request.
