Big congratulations to BiSSL Ph.D. student Abheek Chatterjee for his paper “Ecology‐inspired resilient and affordable system of systems using degree of system order” – which investigates applying ecological resilience measures to the design of Systems of Systems (SoS) and has now been published!
Abstract: This research tests the value of using an ecology-inspired architectural metric, called the metric Degree of System Order (DoSO), to identify resilient and affordable engineered System of Systems (SoS) architectures. Analysis of long-surviving biological ecosystems (nature’s resilient SoS) using DoSO has revealed a unique balance of efficient and redundant interactions in their architectures. This balance is hypothesized to enable both effective resource utilization under normal operation and adaptability to survive and recover from perturbations. Optimal trade-off between resilience (the ability to survive and recover from disruptions) and affordability is highly desirable in engineering SoS as well. To test this analogy, the resilience vs. affordability tradespace of a large number of notional SoS architectures is investigated using the DoSO metric. Results indicate that the majority of Pareto optimal SoS architectures, under various disruption scenarios, lie in the ecologically identified favorable DoSO range. Further, SoS architectures within this DoSO range were found to have better resilience and affordability attributes, in general, than the architectures outside it. Evaluation of the DoSO metric does not require detailed simulations and is the first network architecture metric to consider resilience vs. affordability trade-offs, making it a valuable addition to the SoS engineering toolset.

Three BiSSL students have had conference papers accepted to the 2021 International Design Engineering Technical Conference! Ph.D. candidate Abheek Chatterjee and MS student Tyler Wilson have co-authored a paper on modifying bio-inspired system design methodologies for supply chains, enabling the impact of storage to be considered when applying resilience characteristics from nature. MS student Garrett Hairston has had his first, first-authored paper accepted that focuses on using a system perspective to develop net-zero design guidelines for multi-use (industrial, residential, commercial) communities from biological food webs.
Abstract: “Supply chain policies and design efforts are traditionally focused on efficiency objectives such as reducing operational costs. With the occurrence of the most devastating pandemic in decades and the continually increasing prevalence of natural disasters, this focus has been challenged, and the need to focus on supply chain resilience has become apparent. Achieving long-lasting sustainable development in supply chains requires a balance of efficiency-focused measures that enhance economic and environmental sustainability and resiliency measures. Ecological Network Analysis has revealed a unique balance between pathway efficiency and redundancy in ecosystems’ network architecture. This enables both efficient operations under normal circumstances and resilience to perturbations. This same analysis can be used to evaluate the balance of sustainability and resilience in supply chain networks, providing insights into what kind of supply chain design and policy decisions lead to more ecosystem-like architectures. This study lays the groundwork for such efforts by studying four supply chain topologies (formed by prevalent supply chain strategies) using ENA. Inventory (storage) is not well understood in the typical flow analysis used in ENA but is an essential facet of supply chain design and must be included in a supply chain analysis. This study overcomes this limitation by proposing a method to include inventory in the ENA framework. The analysis conducted revealed two significant insights: (a) the agile supply chain strategy is the most ecologically similar and (b) it is possible that there are optimal inventory levels (given partnership strategies) to utilize bio-inspiration in supply chain design.”

Abstract: “Much emphasis is placed on the role of Net Zero Communities (NZCs) in achieving a sustainable future. Systems research on the topic, including the application of bio-inspired techniques already used on other human networks, is currently hindered by the lack of case studies documenting the structure and quantity of energy, water, and waste flows within realistic NZCs. This work proposes and preliminarily tests a method of generating a database of hypothetical-realistic NZCs by expanding the system boundaries for well-documented Eco-industrial Park (EIP) networks. The expansion includes residential and commercial actors from the community surrounding the EIP. Past studies using Ecological Network Analysis (ENA) to improve the environmental and economic performance of these EIPs have resulted in a quantitative database of case studies. Combining these industrial hubs to nearby residential, commercial, agricultural, etc. actors can generate potential multi-use networks on which similar design work can be conducted. Three EIP to NZC cases are generated and analyzed focusing on their system structure. Cyclicity, an ENA metric used to quantify the presence and complexity of cyclic pathways in a network, has been shown to promote the efficient use of resources in both biological and human networks. Cyclicity values for the original EIP networks, the community additions, and the potential NZC case studies reveals that there are many meaningful interactions that occur between actors that are only visible once the system boundaries are expanded to the NZC level. This offers a glimpse into the potential benefits of approaching the NZ problem, and sustainable living more generally, on a system scale – an analysis that will be further enabled by the generation of an NZC database initiated by this work.”

BiSSL MS student Samuel Blair has had his first, first-authored conference paper accepted to the American Society of Engineering Education 2021 annual conference! The conference was to be held in Long Beach, CA but unfortunately has since shifted to an entirely virtual format. The paper is titled “Bipartite Network Analysis Utilizing Survey Data to Determine Student and Tool Interactions in a Makerspace” and is a collaborative work with our partners at Georgia Institute of Technology, Dr. Julie Linsey and her MS student Henry Banks. The conference will take place July 26-29, 2021.
Abstract: “Engineering makerspaces are a powerful new tool in the educators’ toolbox. A growing body of empirical data demonstrates their benefits to student learning, but more needs to be done to ensure they meet their full potential. Analyzing the design of these spaces to maximize student tool interactions and identify barriers to entry supports goals for these spaces to be inclusive environments were all students are comfortable. The representation of student interactions with tools in a graph form enables analysis on the tools by mapping combinations between tools and shared student. The bipartite model of the network allows for students to be the “actors” while the tools are the “events” that students interact with. Using the one way interaction allows for a matrix simplifying the complex interactions in the space. The matrix can then be manipulated to yield important information about makerspaces. The results of this ongoing research propose advice regarding what tools and tool types are the most accessible to students, primarily high interaction tools such as basic 3D printers and handheld tools. Utilizing the analysis can also reveal how tools depend on higher interaction tools such as the advanced forms of 3D printing, as well as what student groups have may need extra support or outreach to increase their inclusion.”

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.”
