System-of-Systems Approach Optimizes Circular Supply Chains
Category: Resource Management · Effect: Strong effect · Year: 2023
Viewing a circular supply chain as a 'system of systems' allows for a more comprehensive analysis of its components, interactions, and enablers, leading to more effective implementation of resource-efficient strategies.
Design Takeaway
Adopt a systems-of-systems perspective to map and analyze all components and interactions within a circular supply chain, enabling targeted interventions for resource efficiency.
Why It Matters
Understanding the complex interdependencies within a circular supply chain is crucial for designers and engineers aiming to minimize waste and maximize resource utilization. This systemic perspective enables the identification of critical leverage points for improving the overall efficiency and circularity of product lifecycles.
Key Finding
By treating a circular supply chain as a complex system of interconnected systems, and by adapting assessment tools like Life Cycle Assessment, designers can better understand and manage the flow of resources to achieve greater efficiency and circularity.
Key Findings
- A 'system of systems' perspective is effective for analyzing circular supply chains.
- Modifying LCA functional unit definitions is necessary to account for dynamic supply chain boundaries in circular models.
- Network theory can identify critical players in a circular supply chain system.
Research Evidence
Aim: To develop a theoretical framework for analyzing and theorizing circular supply chains within their system context, focusing on the technical cycle of the Circular Economy.
Method: Systems Engineering Approach and Life Cycle Assessment (LCA) integration, System-of-Systems (SoS) perspective, Network Theory.
Procedure: The research proposes a 'CE system context' for supply chain SoS, integrates R-strategies (reduce, reuse, recycle, etc.) into LCA by modifying the functional unit definition, introduces measures to assess R-strategy effectiveness, and uses network theory to evaluate player criticality.
Context: Circular Economy, Supply Chain Management, Technical Cycle
Design Principle
Complex systems require holistic analysis; optimize the whole by understanding the interactions of its parts.
How to Apply
When designing a product or service intended for a circular economy, map out all upstream and downstream processes as interconnected systems. Identify key players and their roles, and use adapted LCA to assess the resource impact across the entire value chain.
Limitations
The proposed framework's application and validation in diverse real-world scenarios require further empirical study.
Student Guide (IB Design Technology)
Simple Explanation: Think of a circular supply chain like a set of nested boxes, where each box is a different part of the process (like making, using, and recycling). By looking at how all these boxes connect and work together, you can find better ways to save resources and reduce waste.
Why This Matters: This helps you understand the bigger picture of your design's environmental impact and how to make it truly circular, not just in one part but across its entire journey.
Critical Thinking: How might the 'system of systems' approach reveal unintended consequences or trade-offs when implementing circular strategies?
IA-Ready Paragraph: The concept of a circular supply chain as a 'system of systems' (SoS) provides a valuable lens for analyzing resource flows and stakeholder interactions. By adopting this perspective, designers can move beyond isolated optimizations to understand and improve the holistic performance of their designs within a circular economy framework, ensuring that strategies like reuse and recycling are effectively integrated across the entire product lifecycle.
