Zusammenfassung
Complex ecological and socio-economic systems often have to be modelled spatially ex-
plicitly. Therefore, cellular automata (CA) are a widely used method for such applica-
tions. But CA in its original form do not allow to model processes on different time
scales and also define a common grid for all processes. This problem can be overcome
by an extension of CA called HACA, introduced in this short paper. HACA allow multi-
ple-scale modelling of spatially explicit processes based on a formally defined extension
of CA. HACA can be used for practical applications by extending a C++-framework that
allows a maximum of freedom to define local dynamics of cell's behaviour.
