Resilient Systems
Systems that can maintain core functions and adapt to changes, disturbances, and failures while continuing to evolve and develop.
Resilient Systems
Resilient systems are complex structures that can withstand, adapt to, and recover from disruptions while maintaining their essential functions and identity. These systems exist across multiple domains, from natural ecosystems to human organizations and technological infrastructure.
Core Characteristics
- Adaptability
- Dynamic response to changing conditions
- Ability to self-organization in response to stress
- learning-systems capabilities that enable evolution
- Redundancy
- Multiple pathways to achieve critical functions
- Distributed resources and capabilities
- fault-tolerance through overlapping systems
- Modularity
- system-boundaries that contain failures
- Independent yet interconnected components
- Ability to reconfigure without system-wide collapse
Design Principles
Feedback Mechanisms
Resilient systems incorporate multiple feedback-loops that enable:
- Early detection of disturbances
- Response calibration
- Learning from experiences
Diversity
- Multiple solution pathways
