from entrance to boarding. In particular
this study develops a simulation model. Based on the Discrete Event theory, that can be used to build a structure that helps to
predict delay and to produce a logical and rational management of check-in and security checkpoint inside the airport
terminal. The proposed model, tested in the South Italian reality (Capodichino – Naples International Airport), has a modular
architecture and interface, enabling quick and easy model building and providing the capability of being adaptable to the
configuration and operational characteristics of a wide range of airport terminals.
