Seminar: Providing Risk-Informed Decision Support for Resilient Communities

Abstract: Communities, both large and small, are embracing the need to prepare for future hazard events and ongoing stressors through resilience planning, which addresses the ability of a community to recover its services and functions within a specified timeframe, so that the effects of severe disruptions are averted or minimized. Resilience builds upon well-established concepts that include urban planning, hazard characterization, reliability, life safety, risk management, mitigation, and emergency response. It provides a framework to integrate these and other concepts, such as recovery planning and dependencies between multi-disciplinary (e.g., physical, social, and economic) systems. Therefore, computational tools need to be multi-disciplinary and provide risk-informed decision support at the community scale for future hazard events and ongoing stressors.

Recent interactions with communities at workshops and during their resilience activities have identified significant challenges that communities face in selecting appropriate computational tools to support developing and implementing resilience plans. The range of data and tools available, and the resources needed for their use, can be overwhelming for communities. Many communities continue to rely on expert judgment of their staff and consultants. Advancing resilience requires that communities understand and appropriately apply computational tools to inform their community plans and decision options.

Even with these challenges, communities are actively working with available data and tools to advance their resilience plans. Examples of community resilience planning tools and needs and considerations for computational tools will be provided.

Seminar: Physics-driven disaster simulation and its application in community resilience

Abstract: Quantify the performance of the community under multiple potential hazards is important for building a resilient community. In this study, a physics-driven multi-hazard simulation framework based on the city information model (CIM) concept is proposed to evaluate the function loss of the community under the earthquake, fire, and wind disasters. The disaster simulations in the framework are all based on physics-driven models. Consequently, it is more flexible to be employed in different communities compared with data-driven empirical methods. Furthermore, the CIM-powered database unifies the database required for the simulations of different hazards and scales, promoting the modeling efficiency. The regional disaster simulation together with several case studies for real-world communities is introduced in detail to demonstrate the workflow of the framework, including the application of these methodologies in the NHERI SimCenter and San Francisco Bay Area.

Seminar: Resilience, Behavior, and Equity

Abstract: Resilience is a powerful concept in hazard preparedness planning. However, existing conceptualizations and models of resilience offer a limited view of community resilience and how it changes over time. In this talk I present a view of resilience that spans the engineering and social capital perspectives and refocusing resilience as equitable access to essential services. I then discuss the critical role of behavior in influencing how the resilience of a community evolves over time. This talk draws on computational modeling projects spanning a number of hazards and geographies from hurricanes to tsunamis to riverine floods.

Bio: Dr. Seth Guikema is a Professor in Industrial and Operations Engineering and Civil and Environmental Engineering at the University of Michigan. Dr. Guikema’s research is highly interdisciplinary.

Seminar: NHERI SimCenter Computational Framework for Simulating Regional-Scale Impacts of Natural Hazards

Abstract: The Natural Hazards Engineering Research Infrastructure’s Computational Modeling and Simulation Center (NHERI SimCenter) is developing computational workflows for regional simulations of natural hazard disasters. These simulations enable research to combine detailed
performance assessments of individual facilities and infrastructure with comprehensive regional-scale simulations of natural hazard effects on communities. Effective development of platforms for high-resolution regional simulations requires modular workflows that can integrate state-of-the-art models with information technologies and high-performance computing resources. In this presentation, the modular architecture of the computational workflow models is described and illustrated through testbed applications to evaluate regional building damage for an earthquake scenario in the San Francisco Bay Area and a hurricane scenario in Atlantic City. Developed and disseminated as open-source software on the NHERI Design Safe Cyberinfrastructure, the computational workflows are facilitating multi-disciplinary research to develop strategies that can mitigate disruption and facilitate more rapid recovery from natural hazards disasters.

Seminar: Quantifying Seismic Resilience of Infrastructure and Communities: smart tools vs. pragmatic challenges

Abstract: In case of seismic events, the inter-dependency between structural damage and system functionality is key for assessing financial cost and social impact. One of the challenges associated with informed disaster risk mitigation, however, is the quantification of resilience in a feasible, meaningful, and pragmatic manner. This talk focuses on a recently developed, multidimensional (i.e., structural, geotechnical, transportational, financial and social) framework that aims to facilitate resilience enhancement and metrics-based decision-making for infrastructure and communities, using state-of-the-art computational methods, hybrid testing and mobile app agents in different societal contexts. Depending on the system studied, a set of resilience-based indicators is also presented for meeting pre-defined objectives by stakeholders and individual agents. Examples are provided from recent applications in developed and developing countries.

Seminar: The Interdisciplinarity of Community Resilience and IN-CORE

Abstract: Physical infrastructure exists to support society and thus many community-level metrics are socio-economic and related to population and economic stability. As a result, community resilience requires cooperation across and within disciplines, namely engineering, computer science, social science/planning, economics, and policy. Dependencies play a key role and act within networks, across networks, and across disciplines making modeling a complex endeavor. The Interdependent Networked Community Resilience Modeling Environment (IN-CORE) developed by the NIST Center for Risk-Based Community Resilience Planning enables analysts to develop and/or combine models from all disciplines with interacting physics-based/process and data-driven/empirical models for earthquakes, tornadoes, floods, hurricanes, and tsunamis. This presentation will address the interdisciplinarity of these complex modeling approaches, which metrics are tracked to identify stability and improvements in resilience, and demonstrate an example of modeling the event-to-recovery (ETR) modeling process for a tornado striking a mid-size city.

Seminar: Critical Infrastructure Resilience in the Face of Climatological Systemic Risks

Abstract: The 2019 Global Risk Report by the World Economic Forum identified Failure of climate-change mitigation & adaptation; Extreme weather events; and Natural disasters as the top three global risks in terms of their combined likelihood and impact. The series of devastating climatological disasters across the globe in the past few decades clearly demonstrates that our societies are far from being climate resilient. Our societies’ critical infrastructure networks feature a multi-layer, densely interconnected architecture of several dynamic (i.e., evolving with time) networks. These networks include, most notably, the power grid, water & wastewater, transportation, as well as telecommunications, fuel, food supply chain, health care, and financial networks. The interdependence of such networks may be responsible for system-wide failures spreading progressively, through interdependence, from one network to another in a domino-like scenario (known as systemic risks), thereby threatening multiple strata of social life and economy. This talk will highlight some ongoing projects at the INTERFACE Institute employing data analytics to overcome the interdependence-induced complexity influencing infrastructure resilience to climatological risks.

Seminar: SRTI: An Accessible Distributed Computing Platform for Interdisciplinary Simulation of Natural Hazard Scenarios

Abstract: Computational research is widespread in the many fields that contribute to natural hazards research. Yet, transdisciplinary efforts routinely face the challenge of connecting disciplinary models that were not designed from the start to be compatible with one another. Integrated platforms are a natural answer to this problem. However, modifying or extending them requires detailed knowledge of the software that necessitates a dedicated maintenance and development staff. This diminishes their scalability and versatility and acts as a throttle on future growth.

The Simple Run Time Infrastructure (SRTI) was developed to address these limitations. Designed to have a low barrier to use, the platform enables disparate simulators to interact together within a publish-subscribe modeling environment. Each simulator represents one part of a disaster scenario and is viewed as a black box that subscribes to data it needs from other simulators and/or publishes its results for other simulators to use. The key advantage is that researchers from various parts of a project (say civil engineering) do not need to know, and may not have the training to know, the details of how simulators from other parts of the project (e.g. economics, social science, or health) work. A cross-language simulation of a time-dependent seismic resilience analysis is presented to demonstrate the scalability and usability of SRTI.

University of Michigan

Workshop: Hands-on Workshop: Creating a Hybrid Simulation System Using the Simple Run Time Infrastructure Software

Abstract: This hands-on workshop’s goal is to introduce the Simple Run-Time Infrastructure software toolkit (SRTI) to the participants, and provide a template project consisting of multiple simulators, each with a specialized purpose, relating to a natural-disaster scenario. It will take place after the feature talks.

The SRTI is a free, open-source solution developed at the University of Michigan, and enables researchers to connect computer programs and simulators written in different languages, to share data during execution, and to design hybrid systems using disparate simulator modules, with a primary goal of being user friendly. This hands-on workshop will explain what the SRTI is, and provide an example on how to use it.

The Java Runtime Environment (JRE) is required to run the SRTI. Please install it prior to the workshop. Refer to icor.engin.umich.edu for more information on supported operating systems and languages. Participants will need to use their own computer systems at home to take part. Basic coding skills in any programming language are required.
