Abstract: 

System analysis is a theory-based approach with a wide range of
practical applications for interdisciplinary co-operation that was
derived from the General Systems Theory, as introduced by Bertalanffy
and others. Formerly being developed as an analytical instrument, it has
now become also an integral part of model development. The method
starts with the delimitation of the investigated system from the
surrounding context, the specification of its compartments, key factors,
driving forces and how these interact with each other. To gain a
conceptual overview, a cause–effect diagram of a system can be
constructed to sketch the influences between the investigated
components. Such a graphical examination can be refined in a next step
into a flow-diagram (flow chart) that depicts the compartments,
connections and controls of the system. This tool is of considerable
help when developing model systems further on the basis of differential
equations, as it enables to characterize time-dependent quantitative
changes of the components as a result of their interactions. Over the
recent years, object-oriented systems analysis (OOSA) has been
established as a structural extension of the classical systems analysis.
By using the object-oriented programming approach, OOSA enables to
represent and subsequently simulate dynamic systems which change their
structure over time. We provide examples of the resulting complex
interaction networks from marine fisheries and functional plant
architecture.
