Circular Systems Engineering: A Novel Paradigm for Sustainable Systems Design, Development, and Lifecycle Management

Core Concepts

Circular systems engineering is a novel paradigm that adopts the circularity principle of circular economy to enable truly sustainable systems engineering practices.

Abstract

The paper introduces the concept of circular systems engineering, a novel paradigm for systems sustainability. It defines two key principles to implement circular systems engineering: End-to-end sustainability: Reasoning about sustainability must scale from the scope of single engineering activities to the overall engineering process and networks of processes. This allows for assessing sustainability and finding trade-offs across the entire value chain. Bipartite sustainability: Sustainable systems and sustainable engineering methods are equally important and form an inseparable unit when assessing sustainability. Incurring sustainability debts along the engineering process might render the overall systems engineering endeavor unsustainable. The paper outlines typical organizational evolution patterns that lead to the implementation and adoption of circularity principles, and highlights key challenges and research opportunities for the modeling community in supporting circular systems engineering. These include: End-to-end process modeling and enactment methods to assess and optimize sustainability across engineering process networks Modeling and simulation techniques to comprehensively evaluate the sustainability of systems and engineering methods, and find trade-offs among different sustainability goals Leveraging digital enablers like digital twins to govern end-to-end processes and support sustainability objectives

Stats

The paper reports the following key statistics: Manufacturing industries account for nearly a third of the global energy consumption and produce 36% of CO2 emissions worldwide. The ICT sector currently contributes to about 2-4% of global CO2 emissions, which is projected to increase to about 14% by 2040. The ICT sector should decrease its CO2 emissions by 42% by 2030, 72% by 2040, and 91% by 2050 to align with the rest of the economy. The amount of discarded electrical or electronic devices, known as e-waste, is recognized by the World Economic Forum as the fastest-growing category of waste.
