Transition management thus equates to designing and implementing such an assemblage. Agent-Based Models (ABMs) may be used for ex-ante assessment of transition assemblage alternatives. To help determine whether the design of a particular model is fit for its purpose, we have developed a typology. Three models were assessed: 1 a model on the impact of CO 2 policy on the power production sector 2 a model on the transition of the global Liquefied Natural Gas (LNG) infrastructure 3 a model on the imminent transition caused by the arrival of Light-Emitting Diode (LED) lighting systems. All three models can be used to compare transition assemblage alternatives and could be adapted to assess regulatory adaptability.
