The GRAMS reference model defines single agents as well as the
simulation of a model containing multiple agents, thus the GRAMS
reference model applies to the micro-level as well as to the macro-level
of an agent-based model. The interrelation between those two levels of
modeling is illustrated in Figure 6.3 and with respect to the GRAMS
reference model the following distinction is adopted:
