Three models were developed; a hybrid system dynamics-discrete event simulation model, a system dynamics model and a model from a new simulation method inspired by agent flocking.
Þrjú líkön voru þróuð, blendings (e. hybrid) hermilíkan sem samanstendur af kviku kerfislíkani (e. system dynamics model) og strjálu-atburða hermilíkani (e. discrete-event simulation model) og nýrri tegund líkana sem er í ætt við einingalíkön (e. agent-based models).
