Making subsections in network-dataset for using location allocation in ArcMap?Geographic Information Systems
When should we use location-allocation model?
These models are most commonly used to locate ‘outreach’ services, such as ambulance or fire stations, where service planners are keen to ensure that no one is more than a given distance (or time) from such a station.
What is network allocation in GIS?
It contains line features that connect demand points to the facilities they are allocated to. If a demand point is allocated to more than one facility, it has one line for each facility it is allocated to. If a demand point is not allocated to any facility, it won’t have any corresponding lines.

What is a location-allocation problem?
Location-allocation (LA) problem is to locate a set of new facilities such that the transportation cost from facilities to customers is minimized and an optimal number of facilities have to be placed in an area of interest in order to satisfy the customer demand.
What are the four options in location planning?
Existing companies generally have four options available in location planning:

- Factor rating method.
- Weighted factor rating method.

How networks are formed in geospatial data?
An urban spatial network can be constructed by abstracting intersections as nodes and streets as links, which is referred to as a transportation network.
How is network partitioning done in GIS?
Network partition is a divvying up of regions in a network to zones or subcategories. These regions are sized based on proximity to specific points in a network. This is common for fire stations in metropolitan areas.
