Investigating Model Behavioural Analysis: A Critical Examination of Two Methods

Two methods for model behavioural analysis are implemented on a simple 2 order nonlinear model. The results of applying Ford’s behavioral approach are compared with those obtained using both system-wide and variable-specific loop eigenvalue elasticity analysis. Differences in the division of the time span into analysis intervals are identified as are discrepancies in the outcomes. The effort required for implementation and the necessity for automation also differ substantially. We consider Ford’s method readily understandable, whereas the mathematically more powerful eigenvalue elasticity analysis poses difficulties
