Summary
Calculates exponent values for use in the Huff Model tool.
Usage
The output exponents are based on attractiveness values of the existing facilities and their spatial relationship to customer points.
Customer point data is a required input.
The Huff Model Calibration output is stored in the Business Analyst container in the Catalog pane.
Exponent values are correlated to the market defined by the inputs. Although they can be applied to additional markets, they may be less reliable in those scenarios.
The Huff Model Calibration output can be applied to the Huff Model tool.
Syntax
HuffModelCalibration(in_facility_features, facility_id_field, in_customer_features, link_field, in_sales_potential_features, sales_potential_id_field, out_calibration, attractiveness_variables, {customer_weight_field}, {distance_type}, {distance_units}, {travel_direction}, {time_of_day}, {time_zone})| Parameter | Explanation | Data Type |
in_facility_features | The input point feature class representing competitors or existing stores. | Feature Layer |
facility_id_field | A unique ID representing a store or facility location. | Field |
in_customer_features | The input point feature class representing customer locations. | Feature Layer |
link_field | The field used as an ID to assign individual customers to a facility or store. | Field |
in_sales_potential_features | The input polygon feature class used to determine the potential sales market. | Feature Layer |
sales_potential_id_field | A unique ID representing the sales potential area. | Field |
out_calibration | The output calibration file that will contain the calibrated Huff model results, which is the exponent values for the attractiveness variables and distance. The output file extension will be *.huffmodel. | File |
attractiveness_variables [attractiveness_variables,...] | The fields used to determine the attractiveness of each competitor. In many cases, the size of the store is used as a substitute for attractiveness. | Value Table |
customer_weight_field (Optional) | A calculated weighted value assigned to each customer. | Field |
distance_type (Optional) | Defines how distance is calculated based on method of travel. The default value is Straight Line. | String |
distance_units (Optional) | The distance-measuring units to be used when calculating distance. | String |
travel_direction (Optional) | Specifies the direction of travel that will be used between stores and sales potential features.
| String |
time_of_day (Optional) | The time and date that will be used when calculating distance. | Date |
time_zone (Optional) | Specifies the time zone that will be used for the Time of Day parameter.
| String |
