Both static and dynamic material flow modelling (System Dynamics) are used for the holistic analysis of complex systems such as the modelling of global resource models.

This field of work is supported by the following software:

  • Vensim
  • mee!Sankey
  • STAN

 

Static material flow modeling

Static material flow modelling considers the input and output quantities within a fixed system. This makes linear dependencies and the accumulation of potentially usable materials visible, which leads to an increase in transparency within the processes and thus allows potentials for optimization and increased efficiency.

 

Dynamic material flow modeling

Dynamic material flow modelling can be used to investigate dynamic problems in complex social, ecological, economic and systems - i.e. systems characterized by interdependencies and mutual influence (System Dynamics Society 2011).

 

The advantages:

  • Not only is the actual state mapped, scenarios for the past, present or future can also be developed and their implications compared.
  • Influencing factors of the system are considered in the overall context and not separately, whereby complex correlations and causal structures can be analyzed and mapped.
  • The consequences and effects of different decision variants are mapped in order to be able to estimate the effects of individual decisions on a complex system.
