Two BiSSL students, PhD student Abheek Chatterjee and recent MS graduate Colton Brehm, had their first authored peer-reviewed publications presented at the 2020 CIRP Life Cycle Engineering conference. The conference, originally meant to be in Grenoble, France was entirely virtual due to COVID-19.

Abstract: “Supply chain design has traditionally focused on using the shortest path or the minimum number of paths to reduce operational costs. This approach, however, fails to account for a system’s response to external disruptions. A novel supply chain design is proposed that mimics the optimal balance of efficient and redundant pathways found in nature’s resilient ecosystems. A comparison of traditional and bio-inspired supply chain designs are done using a disruption scenario, showing that the bio-inspiration significantly reduces the supply chain’s vulnerability to cascading failures.”Chatterjee, A., & Layton, A.

“The sustainability of industrial practices is a growing point of emphasis in the research and business communities demanding effective systems-level solutions. Eco-Industrial Parks (EIPs), networks of co-located industries connected through mutually beneficial collaborations are a popular systems-level solution but have experienced highly variable degrees of success. Nestedness, a structure prevalent in mutualistic networks found in nature is our design focus for improved outcomes. This paper investigates how ecologically-similar nestedness values in EIPs relate to reductions of freshwater imports. The results indicate a range of nestedness values that support water conservation and critical thresholds for maximizing capital investments.”Brehm, C., Chatterjee, A., & Layton, A. (2020).
