How to enable hierarchies in ArcMap for each network analysis layer?
You can also choose to enable hierarchies in ArcMap for each network analysis layer that you add by following these steps: open the Layer Properties dialog box for your network analysis layer, click the Analysis Settings tab, and click Use Hierarchy. Alternatively, you can perform a normal analysis by unchecking Use Hierarchy.
When to not use hierarchy in network analysis?
If the impedance is not based on time, using a hierarchy may not produce realistic results. For analyses that don’t minimize time, consider solving without using the hierarchy. As long as the network dataset has a hierarchy attribute, you can set any network analysis layer you create to use the hierarchy by default.
Which is more likely in a hierarchical analysis?
Note that while a road in a higher level of hierarchy is more likely to be in the result of a hierarchical analysis, the road is not necessarily more favored by the solver than roads in the lower levels of the hierarchy. Even when you have the option of performing a hierarchical analysis, you can choose to ignore hierarchies.
When to use time based attribute in ArcGIS?
ArcGIS assumes that the highest order of hierarchy is connected. All other network analysis layers, except for service area, employ the hierarchical search method described above. It makes more sense to use a time-based attribute as impedance when performing a hierarchical network analysis.
How to solve a vehicle routing problem in ArcMap?
Solving a vehicle routing problem follows the same workflow as other network analyses. The vehicle routing problem analysis layer stores the inputs, parameters, and results for a given vehicle routing problem.
Which is invalid hierarchy setting during route analysis?
During route analysis, hierarchy settings are invalid, for example, “Invalid max value 2 for hierarchy level 2. Has to be greater than hierarchy value 3 for hierarchy level 1.”
