John Hayward attended the 30th International Conference of the
System Dynamics Society in St Gallen, Switzerland, July 22 – 26, 2012. He presented a paper entitled Model Behavior and the Strengths of Causal Loops: Mathematical Insights and a Practical Method. John also became part of the special interest group in model analysis.
The paper derived analytical results for the strength of casual loops using the pathway participation metric approach to loop strength. A range of models were explained in terms of shifting loop dominance. The paper further demonstrated a numerical method for implementing loop dominance analysis in Stella/Ithink.
