Researchers, organizations, and engineers alike are eliciting an increasing importance to design space system architectures to be more robust and resilient to the dynamic, contested, and congested space environment. However, resilience is a nebulous term with varying qualitative definitions in multidisciplinary fields. Furthermore, no globally agreed-upon method exists for quantifying (and designing) resilience. Without an established metric or definition, optimizing, comparing, and designing resilient architectures is a challenge.

In literature, resilience tends to be associated with a system’s ability to adapt to, respond to, and recover from dynamic or adverse events. Furthermore, resilience terms can overlap with other (though more well-known and well-defined) terms, including robustness, reliability, survivability, etc.

Because of these major gaps, honing a mathematical representation and definition of resilience is imperative for addressing the issue of creating resilient space systems. As we advance our space system technologies, especially through distributed architectures, autonomous decision-making capabilities, and artificial intelligence, how can we measure, design, and adapt such systems to be more resilient to disruptive events? How can we cross-analyze designs or decisions to enable resilient capabilities?

The purpose of this workshop is to address the issues of defining/quantifying resilience and collaborate on brainstorming, discussing, and refining the current state-of-the-art when applied to space system design.

Workshop Goals

This workshop is designed to:

- Serve as a brainstorming session to discuss a unifiable definition and quantifiable metric for resilience,

- Survey the current state-of-the-art and share present considerations and applications of resilience metrics,

- Discuss methods of designing resilient space systems, especially regarding distributed architectures,

- Distinguish resilience from yet relate to well-known and well-defined terms (especially robustness), and

- Provide a collaboration opportunity to refine resilience and define future steps/research areas for improving, applying, and verifying the metric.


We invite authors to submit single-page abstracts with presentations following the SMC-IT 2024 Submission Guidelines to the “What is Resilience? A Workshop on Resilience, Adaptation, and Robustness to Design Resilient Space System Architectures” workshop.

**Single-page abstracts are due by May 31st.**

As the nature of the workshop is to collaborate on and discuss resilience quantification and design methods, single page abstracts with presentations will be accepted (no full paper requirement). Abstracts should entail the following focus/interest topics:

- Literature surveys on resilience

- Applications of resiliency in space system design

- Distributed space system architectures for robust and resilient design

- Applications of resiliency in autonomous systems and artificial intelligence

- Development/application of resilience metrics

- State-of-the-art research on resilient and robust space systems

Authors of abstracts should prepare a 15–20-minute presentation as part of the workshop schedule. Each presenter will have a time allotment of 15-20 minutes plus 2-5 minutes for questions. The workshop will conclude with a group discussion, where attendees, presenters, and authors may collaborate and discuss presented work, future research areas, and remaining questions.

Details regarding SMC-IT 2024 Submission Guidelines may be found at: https://smcit-scc.space/submissions.html .

Submissions may be made at: https://easychair.org/conferences/?conf=smcitscc2024.

Abstracts should follow the template: https://www.ieee.org/conferences/publishing/templates.html . One-page abstracts should clearly demonstrate applicability to this workshop and articulate intended research to be presented during the workshop.
