The NetLP Parallel Arcs node allows you to define multiple pathway capacities with varying costs, to influence the flow in a network. It provides the cost and capacity on an arc for netlp-based ordering.
There is, by default, one arc that is always present in the node (overflow arc), which has a very high cost and infinite capacity. As the name suggests, any overflow from other arcs goes down this path.
Configuring arcs
To configure an arc (in addition to the overflow arc), double click on the node to open its feature editor (Figure 1). Enter the arc’s name, along with its associated cost and capacity. Note that the capacity must be specified as an expression.
To delete an arc, click on the appropriate row and press the Delete key on your keyboard.
Figure 1. NetLP Parallel Arcs node
Enter the following information in the table:
- Name of the arc;
- Cost – Regulated capacity of the arc in the order phase; and
- Capacity – Actual flow in the arc in the order phase. This includes the bypass arc.
Figure 1 shows three arcs configured, each with the same cost.
