Types of network

analysis



• Find the area you can reach from a facility

- Solve for many facilities

- Use multiple break values

- Specify the direction of travel

- Output lines or polygons

- Analyze for different times of the day

Service Area solverperforms coverage analysis

Use the Service Area solver to

find coverage for fire stations

Fire Coverage


Demo


• Route a fleet of vehicles to service

a set of orders

- Vehicle capacities

- Driver specialties

- Work day rules

- Breaks

- Maximum hours

- Time windows on orders

Vehicle Routing Problem solverperforms fleet routing


• Find the nearest facilities from

each incident

- Limit the search distance

- Limit the number of facilities to find

- Travel from the facility to the incident

Closest Facility solverfinds the nearest location

Find the nearest emergency vehicle to

an incident

Dispatching


Demo

http://nadev.arcgis.com/arcgis/samples


• Determine the best location for a facility,

based on demand conditions

- Choose from many different analysis types

- Limit the capacity of facilities

- Analyze for different times of day

Location-Allocation solverperforms site optimization

Use the Location-Allocation

solver to allocate fire

inspectors to inspection

sites

Site selection


Demo


• Generate a matrix of the travel costs from

origins to destinations

- Limit the search distance

- Limit the number of destinations to find

- Analyze different times of day

• Find the best route for visiting a series of stops with minimum cost- Specify time windows on stops

- Find best sequence of stops

- Analyze for different times of the day

Route solverperforms point-to-point analysis
