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
– 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
– 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”
