Constraints are used in the Optimization Analysis and Maintenance Analysis windows. These constraints can be subdivided to allow a more finely tuned optimization. For example, in Optimization Analysis in the PMS module, you could select CCI as an index for constraining treatment costs. This index would apply across all types of roads in the transportation network. However, if you would prefer to have different CCI values for different types of roads, you could use this window to subdivide the CCI constraint by, say, Interstates, Primary, and Secondary. These could then be used to create additional constraint records in the Optimization Analysis window.
This window contains two panes. The left pane shows the constraints that have partitions. For the constraint selected in the left pane, the right pane shows the hierarchical arrangement of the constraint's partitions.
| Note: When you add additional records to the Constraints tab of the Optimization Analysis window, records are only created for child nodes; parent nodes are ignored. |
When you right-click a node in the hierarchy, the system displays a shortcut menu with the following special commands:
