The System Dynamics approach consists in an open environment for software development, the development process, however, in contrast to the Sensitivity model, is poorly structured. The development of a basic model structure is fast, what takes time and needs the relevant data is filling the functions, testing and calibrating. An advantage is the high flexibility within the definition of relations, the capacity of simulation is „only“restricted by data. System analysis tools, however, are less performing. The model platform is lacking transparency; communicating the model thus becomes difficult. The simulation is oriented to integrate the global system as a whole, but there is no spatial dynamics.
System Dynamics approaches in consequence are suitable for quantitative simulation of system behavior over time, if the model functions can be given and the relevant date is available. It is less suitable for interactive communication and system analysis.
