Various aspects of multi-method modelling and its applications in modelling large infrastructure systems like airports
Authors: Barbara Glock, Niki Popper, Felix Breitenecker
Abstract
Large infrastructure systems like airports are complex, consisting of various subsystems that are interconnected dynamically to each other. Modelling only one subsystem, although the research question addresses only that subsystem, can lead to error propagations, as dynamic system effects are underestimated. Extending the system boundaries after identification of the dynamic effects can lead to trade-offs when the chosen modelling method gets to its limits. Combined systems require multi-method modelling where diverse subsystems are modelled with the respectively best fitting modelling method. These subsystems are connected via specifically defined interfaces to get a model that represents the large system. Multi-method modelling allows using all advantages of the different modelling methods by coupling them and give a more natural way of seeing the system. Different coupling methods found in literature are presented and basic concepts for modelling airports and its subsystems are proposed.
