I need help for a network problem,
The problem is a network that have summit and arc.
I need the model to pass metric ton by trucks to the end of the network.
1. I have to add a constraint that if the model use that route, it add 10$ to the total of the model.

2. I have to add a contraint that add 15$ to the total, everytime a truck pass on that route but the maximum weight everytime is 15 metric ton.
(for this one, if I put the fonction IF, it say that my model make a circular reference)

Thank you for your answer :)
