Mitigating Systems Complexity & Unintended Systems Emergent Behaviours through NASA's Digital Twin Strategy

Presented by Michael Grieves

The issue with today's complex systems is that often behaviours emerge that are unforeseen and unwanted. The usual and expensive part of this issue is that these unforeseen and unwanted behaviours do not surface until after the system has been designed and realized. In the worst-case scenario, these unwanted behaviours result in a catastrophic failure. In the best case scenario, we are faced with expensive and time-consuming changes to the system.

Once the system is realized in atoms, i.e., a physical manifestation, the cost and time to make corrections ranges from the costly to the unaffordable. A major way to mitigate this issue is to use bits, i.e., modelling and simulation, in order to test out the system virtually and uncover emergent behaviour that is detrimental to the performance of the system. The NASA DigitalTwin project is a step in that direction.

This presentation outlines the scale and scope of the initial efforts and discusses the path forward.
