“…Furthermore, a multi-stakeholder initiative raising the awareness of the risk of excessive network efficiency (low redundancy) and lack of modularity can lead to better management and contingency plans for the diversification of resource flows in anticipation of future shocks and disruptions. Investigation of these possibilities has already begun, e.g., see, for example, ( Dave & Layton, 2020 ; Kharrazi et al, 2017 ; Kiss & Kiss, 2018 ; Lietaer et al, 2010 ; Panyam et al, 2019 ).…”

Sustainability is increasingly concerned with the complex interactions between nature and society, and we need to seek solutions towards the challenges that threaten humanity's collective wellbeing. Towards this end, it is critical to advance the application of research examining the dynamic interactions of the components of complex social-ecological systems and their emerging properties. A key research area is on advancing tools and strategies relevant to the evaluation and strengthening of resilience. Redundancy, diversity, and modularity are important characteristics of resilience with a high potential for application in various critical social-ecological systems. This paper provides a critical overview of the theoretical underpinnings of modularity and redundancy and their application in measuring resilience of trade networks with implications for public policy and institutional design.

“…The validation in this study was performed using a notional supply chain case-study, but the proposed framework can be applied to any resource and infrastructure network that can be modeled as a network of flows (for example see [52] , [53] , [79] ). A novel feature of the bio-inspired design framework presented here is that it does not merely advocate adding actors of the same functionality, but rather intelligent set up of interactions between existing actors .…”

“…The ecological fitness function, when applied to power grid and industrial water networks, presents promising improvements in the ability of the network to absorb disruptions [52] , [53] . The existing mathematical formulation of the ecological fitness function however is limited to application on networks with only one type of flow (interaction).…”

“…The required modifications are presented and tested on an electric motor supply chain case study (an interdependent infrastructure network with multiple flow types), validating the new formulation through resilience analysis. While previous studies focused primarily on the possible improvements in a network's ability to absorb disruptions through the use of the ecological fitness function [52] , [53] , here we also investigate the recovery following disruptions, providing a more holistic view of the relationship between the ecological fitness function and the resilience of engineering networks.…”

Highlights Novel, bio-inspired resilient resource and infrastructure network design framework. Proposed framework only requires knowledge of network architecture. Valuable tool when information not available for high-fidelity analyses. Shown to be able to analyze complex resource and infrastructure networks. Validated network resilience improvement through supply chain case-study.

“…A systems-level analysis of a network of industries, for example, (as opposed to designing each industry individually) was able to reduce the overall environmental impact of all industries in the network without increasing the cost of the network (thereby maintaining profits) [1][2][3]. Similar system-analyses of water distribution networks and power grids have also resulted in designs that reduced raw material usage, improved use of available resources, and reduced economic damages following disruptions [4][5][6][7][8].…”
