Instance Mangement manages the analysis instance, which is a process to solve the practical problem by analysis in the network model such as path analysis, service area analysis and closest facility. Currently, network analysis has been widely used in electronic navigation, transportation, tourism, urban planning, logistics, electric power, telecommunication, etc.
Instance Management
Click Spatial Analysis > Facility Network Analysis > Network Analysis , and then select any item to open the Instance Management window.

Barrier Node
- Remove : Click Remove in the right-click menu of Barrier Point to remove all the barrier points in the list. If select Remove in the right-click menu of its child node, then you just delete this point.
- Import : Add the barrier points by import, similar to import stops.
- Export : Export all the barrier points in the current instance to save them as point dataset.
Result
- Save as Dataset : Save all the subitems in the analysis results as the dataset. If you select Save as Dataset in its subitem right-click menu, then only the subitem is saved as the dataset. When generating a result dataset, you can select a field as the statistics field, which is the sum of the corresponding field values for all arcs through which the path passes.
