Abheek his paper was written in collaboration with Dr. Richard Malak, in CIE’s SEIKM division titled “Exploring a Bio-Inspired System of Systems Resilience vs. Affordability Tradespace“

Abstract: “The objective of this study is to investigate the value of an ecologically inspired architectural metric called the Degree of System Order in the System of Systems (SoS) architecting process. Two highly desirable SoS attributes are the ability to withstand and recover from disruptions (resilience) and affordability. In practice, more resilient SoS architectures are less affordable and it is essential to balance the trade-offs between the two attributes. Ecological research analyzing long-surviving ecosystems (nature’s resilient SoS) using the Degree of System Order metric has found a unique balance of efficient and redundant interactions in their architecture. This balance implies that highly efficient ecosystems tend to be inflexible and vulnerable to perturbations while highly redundant ecosystems fail to utilize resources effectively for survival. Motivated by this unique architectural property of ecosystems, this study investigates the response to disruptions vs. affordability trade-space of a large number of feasible SoS architectures. Results indicate that the most favorable SoS architectures in this trade-space share a specific range of values of Degree of System Order. This suggests that Degree of System Order can be a key metric is engineered SoS development. Evaluating the Degree of System Order does not require detailed simulations and can, therefore, guide the early stage SoS design process towards more optimal SoS architectures.”

BiSSL PhD student Abheek Chatterjee just had his full-length research paper accepted in the Journal Reliability Engineering &System Safety! The paper, titled “Mimicking Nature for Resilient Resource and Infrastructure Network Design,” investigates the use of ecological robustness – a functional characteristic of ecological food webs, to guide the design of a supply chain case study to improve its ability to survive network disturbances.

Abstract: “Increasingly prevalent extreme weather events have caused resilience to become an essential sustainable development component for resource and infrastructure networks. Existing resilience metrics require detailed knowledge of the system and potential disruptions, which is not available in the early design stage. The lack of quantitative tools to guide the early stages of design for resilience, forces engineers to rely on heuristics (use physical redundancy, localized capacity, etc.). This research asserts that the required quantitative guidelines can be developed using the architecting principles of biological ecosystems, which maintain a unique balance between pathway redundancy and efficiency, enabling them to be both productive under normal circumstances and survive disruptions. Ecologists quantify this network characteristic using the ecological fitness function. This paper presents the required reformulation required to enable the use of this metric in the design and analysis of resource and infrastructure networks with multiple distinct, but interdependent, interactions. The proposed framework is validated by comparing the resilience characteristics of two notional supply chain designs: one designed for minimum shipping cost and the other designed using the proposed bio-inspired framework. The results support using the proposed bio-inspired framework to guide designers in creating resilient and sustainable resource and infrastructure networks.”

Texas A&M Energy Institute Lecture Series

July 2, 2020 12-1pm CT Zoom Meeting

Dr. Debalina Sengupta is the Associate Director of the Texas A&M Engineering Experiment Station’s Gas & Fuels Research Center, as well as the Water, Energy, and Food Nexus Coordinator in the Texas A&M Energy Institute at Texas A&M University.

Abstract: We are witnessing history, and living through it. Never before in recent times has a pandemic spread around the world and paralyzed nations, economies, resources, and most importantly, people, all at the same time. It has exposed vulnerabilities to systems in ways that we are yet to fathom. As we wade through solving the immediate human health concerns and crisis, there is a deeper question that we need to address. The role of different entities and players in the society need to be taken into consideration for determining the resilience to disasters of great magnitude.

Over the past two decades, statistics suggest that the intensity of natural disasters have been increasing, and the damages caused by them have been impacting the lives of millions. Hurricanes and flooding events have increasingly influenced coastal communities and given rise to terms as climate refugees. Disaster management has primarily been a top-down approach from governance perspectives. The Post-Katrina Emergency Management Reform Act of 2006 saw a comprehensive push towards disaster management strategies, and the need for emergency planning and implementation. However, the multiple failures during disasters and the resulting increase in losses to human lives, property, and progress of regions have yet again shown us that a convergent, interdisciplinary research approach is required to address the four stages of disaster management: Response, Recovery, Mitigation, and Preparedness. From analyzing vulnerabilities and risks to identifying root causes and critical elements in the full cycle of disaster management, interventions can be designed for timely recovery and minimizing loss of life. Deriving from concepts of sustainable development, this webinar will provide a framework for resilience studies, and seek to develop partnerships that can bring translational research components for innovative approaches towards disaster resilience.

BiSSL alumn Colton Brehm (MS graduate May 2020) just had his full-length research paper accepted in the Journal of Industrial Ecology! The paper, titled “Nestedness in eco-industrial networks: exploring linkage distribution to promote sustainable industrial growth,” investigates the use of nestedness – a structural characteristic of ecological food webs, to guide the design of Eco-Industrial Networks (EINs) to improve their sustainability, creating a more circular economy.

Abstract: “Eco-Industrial Networks (EINs) have gained support as a solution that simultaneously reduces environmental burdens and promotes economic interests. EINs operate under a mutualistic framework, where waste materials and energy are exchanged between industries to their mutual benefit, creating a diverse web of flows. Recent studies have focused on analogies between food webs (FWs) and EINs, measuring a network’s success at ecological imitation as representative of its sustainability. Studies have focused heavily on the number of links and nodes in a network, but have neglected the economic reality that each investment comes at the opportunity cost of all alternatives. This analysis focuses on the nestedness metric as used by ecologists to address this pivotal facet to the FW-EIN analogy. Nestedness describes an ecological strategy for the position of links between nodes in a network in a way that maximizes network cycling for a given number of connections. This metric presents many advantages for EIN design and analysis, including maturity independence, size normalization, and a strong statistical record in highly mutualistic ecological systems. Application of nestedness to EINs indicates a lower presence of nested structures and more randomness than what is typically seen in FWs. The industrial networks also display a correlation between high nestedness and internal cycles, suggesting that the reuse of materials and energy in EINs can be improved upon by increasing the nestedness of structures.”

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).
