4 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

5 The Challenge Sources of complexity:
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

6 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”

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