- Multiple-scale analysis is an approach that involves studying complex systems and phenomena at different levels of scale or granularity.
- It helps reveal hidden patterns, emergent behaviors, and critical interactions that may not be apparent when examining a system as a whole.
Key Objectives of Multiple-Scale Analysis:
