Class: ChooseBestFacilities
[ AMD Module Require | Legacy Module Require ]
dojo.require("esri.dijit.analysis.ChooseBestFacilities")
Description
(Added at v3.16)
Choose Best Facilities allows you to choose the best locations for facilities. The tool allocates locations with demand for the facilities, in a way that satisfies the specified goal. The widget provides various options to solve specific problems. These options include:
- Allocating to existing facilities
- Minimizing travel time
- Maximizing coverage
- Maximizing coverage with capacity
- Covering a percentage of demand
