  3. Complex Engineered and Natural Systems • Definition: Complex, Complexity (adj., n) • Consisting of interconnected or interwoven parts; • Involved or intricate, as in structure; complicated. • Difficult to understand because of intricacy: • A whole composed of interconnected or interwoven parts • Engineering Complexity -- the condition of being difficult to explain and predict systems behaviors, robust operation of the same. • Complexity in • Engineered systems • Natural systems • Interface of engineered and natural systems

  4. The Challenge • Creation of common principles, unified theories, and methods to design, operate, and protect complex engineered systems. • Sources of complexity: • Too much information, too many components, too many constraints, too many parameters for consideration to accomplish a particular task • Not enough information about essential elements or components of a system or about their interfaces • Not enough information about how elements or components will behave under known or unknown conditions that may lead to unintended consequences

  5. NSF Role • To encourage the community to think about • What is complex system science • Fundamental questions related science of complexity • Questions related to design, control and management of complexz systems • To invest in the development of “science of the complex”

  6. NSF Activities • A series of workshops on complexity • Considering complexity under three topics • Transportation Systems • Biological Systems • Healthcare Delivery
