The analytic evaluation of multi-scale Feynman integrals is difficult due to the presence of various scales of the problem.When exact calculation is very difficult or impossible, systematic approximations may help.The strategy of expansion by regions is a useful method for obtaining the asymptotic analysis of multi-scale Feynman integrals.In this talk, we present a novel method for the identification of regions associated with multi-scale Feynman integrals.
