System Dynamic Modelling




System Dynamic Modelling Using FLAC

General System Theory (Bertalanffy, 1968) indicates there is a general tendency towards integration in the various sciences, natural and social. Such integration seems to be centered in a general theory of systems, which is derived from 'sets of elements standing in inter-relation'.

System dynamics is strongly useful to describe our understanding of real system. Complexity of forest ecosystems and social systems involved in forest management make our knowledge of real systems never complete. Under this circumstance we can use systems analysis and simulation to investigate our hypotheses about how systems work. If we can model how real systems work then scenarios for increasing sustainability and human well being can be hypothesized.

FLAC (Flores Adaptation and Calibration) is a tool to adapt and calibrate a general FLORES system dynamic model, created within the SIMILE environment, to enable policy makers to explore the consequences of alternative policy actions for rural communities.

Within FLAC you can:

  • Change policy inputs
  • Change scenario inputs
  • Change coefficients
  • Change equations
  • Swap one submodel for another
  • Work with submodels saved as stand-alone models
  • Creat new submodels
  • Load new submodels into FLORES
  • Edit the structure of the FLORES model
  • Design new FLORES models from scratch

The ACM will undertake work on "A System Dynamic Model for Creating Scenarios of Adaptive Collaborative management of Forests" in Indonesia (East Kalimantan and Jambi Province), Zimbabwe and Cameroon.

The work is lead by Dr. Ravi Prabhu. Other scientist involved Jerry Vanclay, Herry Purnomo, Stepi Hakim, Mandy Haggith, Chris Legg, Robert Muetzelfeldt and Fergus Sinclair.
