Constraints and Ordering Phases

The order phase comprises of the following steps.

1. Process Water Users:
   1. For each Water User (can be done in parallel - see scenario options):
      1. Calculate and distribute the demands of each Water user
2. Constraint phase:
   1. Traverse the network from the leaf nodes at the top of the network down to the outlet node(s) at the bottom of the network (down the network):
      1. Calculate minimum and maximum constraints at each element and pass the constraints downstream
3. Ordering phase:
   1. Network traversing from outlet node to leaf node (up the network):
      1. Calculate regulated orders and pass upstream
      2. Calculate off allocation orders and pass upstream

Refer to rules-based ordering for details.
