Figure A1.
The diagram illustrates a system dynamics model with multiple rectangular and circular nodes connected by arrows. The structure represents variables such as production rates, recovery processes, and economic measures, with links indicating causal relationships and feedback loops. Several dense clusters show many-to-one and one-to-many connections, highlighting complex interdependencies. Loops illustrate reinforcing and balancing dynamics that influence outcomes across the system. The layout flows vertically and horizontally, with labelled pathways that trace how processes interact and accumulate effects. This comprehensive framework visually represents the interrelated dynamics of production, recovery, and credit within the system.The overall simulation model structure
