2nd PATRES workshp, October 2007
Question how complex systems demonstrate
resilience by absorbing or recovering
from major external perturbations

• OBJECTIVES
• Develop tools (including software) and
  methods for pattern resilience in complex
  systems
• Patterns evolving statistical
  regularities or structures
• Resilience defined as a viability
  problem in the pattern state space
• Synthetic (low d) description of IBM
  complex dynamics
• Develop new methods and tools for defining action
  policies in order to maintain
• or restore desired pattern dynamics in a complex
  system
• Test and illustrate these innovations on a set of
  case studies
