•The lower, upper and cost of arcs could be
changed over time.
factor might be
assigned to the flows on each arc, such as leakage, evaporation, breeding, interest rate,
function could be
assigned to each arc.
•Some constraints could be added to the constraints, like utilities (water, gas, electricity) supply system, i.e.
the flow of some arcs must
be the same.
In the area of Minimum Cost Flow, some particular problems may be arisen.
