2. Overview of the SD methodology and previous studies using SD
The System Dynamics Methodology is a simulation methodology based on systems theory. The characteristics
of systemic approaches adopted in the systems theory were well presented by Beard (1999) in which 14 systemic
ideas were provided. The methodology can facilitate understanding of a system by extracting essential structures of
its working mechanisms and development of efficient management strategies based on an analysis of feedback
structures inherent to the system.
