Decision Sciences and Visualization

Developing models and simulations that shed light on how human behavior affects decisions.

The decision science pillar has potentially been best described by Wong-Parodi et al in their 2016 article in Nature Climate Change entitled “A decision science approach for integrating social science in climate and energy solutions.” In that article, decision science was described as providing analytical frameworks that can accommodate the development of decisions for a diverse set of domains by formalizing the decision-making process. The decision-making process is formalized by characterizing the choices that a rational actor would make with perfect information and contrasting thaw with the decisions made by actors under bounded rationality, where only limited information is available. By understanding the differences, strategies are then developed to bridge the gap between the ideal decision and observed reality. Ultimately, the decision science pillar seeks to collaboratively work with subject matter experts and decision-makers to facilitate decisions that incorporate both the value outcomes as well as the risks and uncertainties.

Decision science draws from many disciplines including but not limited to behavioral economics, game theory, statistics, and risk analysis; to develop models and simulations that shed light on how uncertainty and human behavior affect decisions. The goal is to provide analysis that can be clearly communicated and utilized to make decisions in line with specified ideals.

The Applied Visualization Laboratory (AVL) staff combines hardware, software, and interaction expertise to develop innovative 3D capabilities in scientific data visualization, immersive analytics, virtual training experiences, remote collaboration and telepresence, and CAD/engineering modeling. We develop and deploy these capabilities on a variety of platforms: head mounted displays (HoloLens 2, Oculus Quest, HTC Vive Pro, Magic Leap), through the web and desktop (A-Frame, Unity), and in our state-of-the-art four-sided CAVE. We also employ a high-precision, high-resolution LiDAR scanner to create true to scale, true to life immersive environments.

Immersive VR/XR/AR at AVL is currently applied to multiple disciplines of science and research that support the key strategies at INL and CAES to advance analysis, explore data and models, and presentation of results.

Visualization is our passion and we have incorporated education and outreach into our mission through internships and collaborations with universities. We also hold positions on a variety of boards and review panels in the visualization community.

We see collaboration as a key for success and welcome opportunities to strengthen your research.

Collaborations & Projects:

Logistics and scale-up of cellulosic biomass supply chains – Developed a project with ExxonMobil to inform decisions around supply chain topologies that can be scaled to supply domestic cellulosic biorefineries consuming at minimum 10,000 dry tons/day, while identifying the economic and technological gaps. Lessons from failed biorefineries suggest that managing feedstock quality throughout the supply chain is necessary to achieve nameplate biorefinery capacity. INL will investigate biomass midstream operations utilizing a Quality by Design approach to meet the critical quality factors that will facilitate scale-up.

Decision support for recycling of e-wastes – Received funding from the Remade Institute, to develop a decision support framework (DSF) for e-waste recycling and refurbishment that is spatially explicit and accounts for dynamic market conditions for recycling recycled and refurbished commodities. This DSF will identify optimal supply chain configurations that reduce recycling/refurbishing costs and energy consumption based on available technology, market conditions, and the spatiotemporal relationships of supply chain actors. The purpose of the model is to provide insights on questions important to the industry (e.g., What configuration of machinery maximizes the recovery of a certain product stream? How far can the collection radius be increased to capitalize on favorable market conditions? etc.) Additionally, the model will improve industry performance (recycling rate, cost, efficiency of material use in highest valued applications, etc.) by providing a system-level understanding of e-waste recycling supply chains from local to continental scales.

Land suitability for the production of dedicated bioenergy crops – A geospatial multi criteria site suitability framework was developed under the Integrated Landscape Management (ILM) project to support decision-making for incorporating bioenergy crop production within agricultural landscapes. Converting low-yielding subfields within agricultural production fields to energy crop production has been demonstrated to improve field profitability, biomass availability and soil carbon sequestration, and mitigate soil erosion. ILM is a strategy developed to integrate biomass production into agricultural production fields to reduce feedstock access costs while improving the sustainability of crop production systems. The purpose of the framework is to identify fields in which an ILM strategy will likely result in maximized economic and environmental benefits. Evaluation criteria were developed across three domains: agronomic, field operability, and environmental. The set of criterias was established to develop a linear fuzzy-logic prediction model with binary constraints, which was used to calculate the site suitability index for each field. Built using open source software and data, the framework is agile, computationally efficient, and capable of assessing large regions spanning multiple counties.

Simulating the variability impacts to preprocessing systems – Utilized discrete event simulation to analyze the impact of feedstock variability on the economics and equipment decisions for first generation cellulosic biorefineries. The method utilizes a mathematical/logical model of the physical system that portrays state changes at precise points in simulated time. Through the use of this model, we were able to define a new metric, Overall Operating Effectiveness, that summarizes the performance of the system in terms of both material quality and attainment of operational capacity. Overall Operating Effectiveness is calculated by taking the product of the percentage of capacity achieved and the percentage of the units of material that meet a defined quality specification. Overall Operating Effectiveness has benefits over more traditional metrics of system performance in that both throughput and output quality are considered.

Decision Support for Recycling of e-Waste

Received funding from the Remade Institute, to develop a decision support framework (DSF) for e-waste recycling and refurbishment. The DSF provides insights on questions important to the industry and will improve industry performance  by providing a system-level understanding of e-waste recycling supply chains from local to continental scales.

Land Suitability for Production of Dedicated Bioenergy Crops

A geospatial multi-criteria site suitability framework was developed to support decision making for incorporating bioenergy crop production within agricultural landscapes.

Applied Visualization Laboratory (AVL)

The Applied Visualization Laboratory contains several 3D immersive environments for scientists and engineers to walk into their data, examine it, and provide deep analysis in pursuit of their research. As mixed, virtual, and augmented reality technology evolves, the opportunities for portable, in-depth analysis of complex data sets increases. Augmented reality solutions are envisioned to allow researchers to have CAVE-like experiences anywhere. Web-based 3-D geographic information systems, mobile applications (for both phone and tablet) and serious games (games built for training or educational purposes) allow users to conduct research at their desks or in the field, enabling discovery outside the lab. Virtual reality exploration systems offer the ability to create visualizations of large data sets that can be projected and run in real-time simulations. Using six-degrees-of-freedom input devices – which allow a body to move forward and backward, up and down, left to right – and stereoscopic output, they offer the benefits of more realistic interaction.

The Center for Advanced Energy Studies (CAES) opened its first Cave Automatic Virtual Environment (CAVE) in 2010. With the new CAVE installed in 2017, CAES’s Applied Visualization Laboratory is even better equipped to provide researchers from universities, industry and government agencies with a user facility where they can visualize and address scientific and technical challenges.
