Hello Eduardo,

I found the following paper to be insightful for finding
better formulations:

Norbert Ascheuer, Matteo Fischetti, Martin Grötschel
Solving the Asymmetric Travelling Salesman Problem with Time Windows by 
Branch-and-Cut
Appeared in: Math. Program., Ser. A, Vol 90, No 3: 475-506 (2000)

Best regards

Xypron
