NETWORK FLOWS

THE LABELLING PROCEDURE

Use the forward facing arrow to indicate the spare capacity in that arc

- the amount by which the flow can be increased - the excess capacity.

Use the backward facing arrow to indicate the flow along the arc,

i.e. the amount by which the flow could be decreased - the back capacity.

We now look for Flow Augmenting Paths

There are no other flows through the network

as every route is now blocked by a saturated arc.

Initial Flow: SACT Flow 3

SBDT Flow 4

Next path is SBCDT Flow 1

Next path is SABCDT Flow 1

One such path is SBCT Flow 1

The final flow along each arc should then

be represented on a fresh diagram:

The Maximum Flow is 10
