Output from SolveLocationAllocation

After successful execution of SolveLocationAllocation, the service returns the chosen facilities, participating demand points, connecting lines between demand points and the facilities to which they were assigned, and the status of whether the analysis was successful. This information is output in the output parameters described below.

output_facilities

This provides access to the chosen, required, and competitor facilities, as well as any candidate facilities that were not chosen.

This parameter supports the following fields. In addition to these fields, the parameter also includes all the fields from the input facilities used for the analysis.

FieldDescription

Name

The name of the facility. The values for this field are copied from the Name field on the input facilities.

FacilityOID

The ObjectID value of the corresponding input facility feature. This field is often used to join information from the input facilities.

FacilityType

The best facilities, or those that are chosen in the analysis, are indicated in this field. The facility types are as follows:

  • 0 (Candidate)—The service didn't choose the candidate facility to be part of the solution.
  • 1 (Required)—Prior to submitting the analysis, the facility was designated as required; therefore, it is part of the solution regardless of how much demand it captured.
  • 2 (Competitor)—The facility represents your rivals and will remove demand from the problem. Competitor facilities are specific to the Maximize Market Share and Target Market Share problem types; they are ignored in other problem types.
  • 3 (Chosen)—These are the chosen facilities; that is, they are candidate facilities that capture the most demand.

Weight

The relative weighting of the facility, which is used to rate the attractiveness, desirability, or bias of one facility compared to another. The values for this field are copied from the Weight field on the input facilities.

Capacity

The amount of weighted demand the facility is capable of supplying. The values for this field are copied from the Capacity field on the input facilities.

DemandCount

A count of demand points allocated to the facility. A nonzero value means the facility was part of the solution, either as a required, competitor, or chosen facility.

DemandWeight

The sum of the effective weight from all demand points that were allocated to the facility. The value is the sum of all the Weight values from the demand points that were allocated to the facility. In the case of the Maximize Attendance and Market Share problem types, the value is an apportioned sum of the Weight field values, since these problem types allow demand to decay with distance or be split among many facilities.

Total_Minutes

The sum of travel time in minutes between the facility and each of the demand points that were allocated to the facility.

This field is included only if the travel mode set for the analysis has an impedance attribute that is time based.

TotalWeighted_Minutes

This field stores the cumulative weighted cost in minutes for a facility. The weighted cost for a demand point is its weight multiplied by the least-cost path between the facility and the demand point. The weighted cost for a facility is the sum of all the weighted costs of demand points that are allocated to the facility.

For example, if a demand point with a weight of 2 is allocated to a facility 10 minutes away, the TotalWeighted_Minutes value is 20 (2 x 10). If another demand point with a weight of 3 is allocated to the same facility and is 5 minutes away, the TotalWeighted_Minutes value increases to 35 (3 x 5 + 20).

This field is included only if the travel mode set for the analysis has an impedance attribute that is time based.

Total_Miles

The sum of travel distance in miles between the facility and each of the demand points that were allocated to the facility.

This field is included only if the travel mode set for the analysis has an impedance attribute that is distance based.

TotalWeighted_Miles

This field stores the cumulative weighted cost in miles for a facility. The weighted cost for a demand point is its weight multiplied by the least-cost path between the facility and the demand point. The weighted cost for a facility is the sum of all the weighted costs of demand points that are allocated to the facility.

For example, if a demand point with a weight of 2 is allocated to a facility 10 miles away, the TotalWeighted_Miles value is 20 (2 x 10). If another demand point with a weight of 3 is allocated to the same facility and is 5 miles away, the TotalWeighted_Miles value increases to 35 (3 x 5 + 20)

This field is included only if the travel mode set for the analysis has an impedance attribute that is distance based.

Total_Kilometers

This field is analogous to the Total_Miles field, except values are in kilometers instead of miles.

TotalWeighted_Kilometers

This field is analogous to the TotalWeighted_Miles field, except values are in kilometers instead of miles.

Total_Other

A sum of travel cost in unknown units between the facility and each of the demand points that were allocated to the facility.

This field is included only if the travel mode set for the analysis has an impedance attribute that is neither time based nor distance based.

TotalWeighted_Other

This field stores the cumulative weighted cost in unknown units for a facility. The weighted cost for a demand point is its weight multiplied by the least-cost path between the facility and the demand point. The weighted cost for a facility is the sum of all the weighted costs of demand points that are allocated to the facility.

This field is included only if the travel mode set for the analysis has an impedance attribute that is neither time based nor distance based.

SourceID

CurbApproach

The direction a vehicle may depart from or arrive at the facility. The values for this field are copied from the CurbApproach field on the input facilities.

Status

Indicates the status of the point with respect to its location on the network and the outcome of the analysis. The possible values are the following:

  • 0 (OK)—The point was successfully located on the network.
  • 1 (Not Located)—The point was not successfully located on the network and consequently was not included in the analysis.
  • 2 (Network element not located)—The network element identified by the point's network location fields can't be found. This can occur when a network element where the point should be was deleted, and the network location was not recalculated.
  • 3 (Element not traversable)—The network element that the point is located on is not traversable. This can occur when the element is restricted by a restriction attribute.
  • 4 (Invalid Field Values)—Field values fall outside a range or coded-value domain. For example, a negative number exists where positive numbers are required.
  • 5 (Not Reached)—The point can't be reached by the solver. The point may be on a separate, disconnected area of the network from the other inputs, or barriers or restrictions prevent travel to or from the point.
  • 6 (Time window violation)—The point could not be reached within the designated time windows. This status only applies to network analysis types that support time windows.
  • 7 (Not located on closest)—The closest network location to the point is not traversable because of a restriction or barrier, so the point has been located on the closest traversable network feature instead.

solve_succeeded

Use this parameter to determine if the analysis was successful.

output_result_file

Use this parameter to access the results from the analysis as a .zip file containing one or more files for each output. The format of the individual file is specified by the Output Format parameter. The parameter value is not populated when the Output Format parameter is set to Feature Set.

When a file-based output format—such as JSON File or GeoJSON File—is specified, no outputs are added to the display, since the application (such as ArcMap or ArcGIS Pro) does not draw the contents of the result file. Instead, the result file is downloaded to a temporary directory on your machine. In ArcGIS Pro, the location of the downloaded file can be determined by viewing the Output Result File parameter value in the entry corresponding to the tool execution in the geoprocessing history of your project. In ArcMap, the location of the file can be determined by accessing the Copy Location option in the shortcut menu on the Output Result File parameter in the entry corresponding to the tool execution in the Geoprocessing Results window.

output_network_analysis_layer

Use this parameter to access the network analysis layer file that stores the analysis settings and the inputs and outputs used for the analysis. The parameter value is populated only when the Save Output Network Analysis Layer parameter is set to True.

The file is downloaded to a temporary directory on your machine. In ArcGIS Pro, the location of the downloaded file can be determined by viewing the Output Network Analysis Layer parameter value in the entry corresponding to the tool execution in the geoprocessing history of your project. In ArcMap, the location of the file can be determined by accessing the Copy Location option in the shortcut menu on the Output Network Analysis Layer parameter in the entry corresponding to the tool execution in the Geoprocessing Results window.
