A multi-level explanation of the process of innovation
This research models the process of innovation with an iterative multi-method model made up of a system dynamic (SD) model and an agent-based model (ABM). This method is a tested and validated modeling process for the study of dynamic processes that take place during disequilibrium (Ross and …

Application of Agent-Based Modeling: Simulating Financial Systemic Risk and Contagion within Housing and Financial Markets
<p>This dissertation presents an agent-based model (ABM) to model systemic risk in the housing and financial markets from 1986 to 2017 and provides a unique approach to simulating the financial market along with demonstrating the phenomenon of emergence resulting from the interconnected-behavior of …

Agent-based Modelling and Social Theory Reveal How People Change Their Yards in Response to Wildlife
… 2) conducted experiments with Noticing Birds, an agent-based model (ABM) simulating a socio-ecological system of urban yards, residents, and bird populations. We organized the literature with a framework based on the Theory of Planned Behavior and found that current studies in this field are …

Modelling evolution of genome size in prokaryotes in response to changes in their abiotic environment
… response to a less predictable environment. An agent-based model (ABM) of genome evolution in an free-living prokaryotic population has been proposed. Using the classic Hutchinson niche space model, a gene was defined as a Gaussian function over a corresponding niche dimension. The cell can have …

Computer Experimental Design for Gaussian Process Surrogates
… are still computationally demanding. A surrogate model or emulator, is often employed as a fast substitute for the simulator. Meanwhile, a common challenge in computer experiments and related fields is to efficiently explore the input space using a small number of samples, i.e., the experimental …

Assessing Working Models' Impact on Land Cover Dynamics through Multi-Agent Based Modeling and Artificial Neural Networks: A Case Study of Roanoke, VA
… urban landscapes. While existing urban growth models (UGM) offer insights into environmental and economic impacts, There is a need to study the urban phenomena from the bottom-up style, considering the essential influence of individuals' behavior and decision-making process at disaggregate and …

Economic evaluations of vaccines in Canada: Exploring the epidemiologic and economic impact of chickenpox vaccine strategies in Canada using an agent-based model
… or effectiveness of the vaccine. We built an agent-based model (ABM) to aid in the understanding of chickenpox and shingles disease dynamics, to measure the cost-effectiveness of chickenpox vaccination and to help guide health policy decision-making. Chickenpox is a childhood disease caused by …

Understanding the influence of individual behaviour and social networks in sustainability transitions.
… survey (N=474), a lab experiment (N=134) and an agent-based model (ABM) to explore how a change towards sustainable food purchasing may be achieved in society. The methodological approach of this thesis is quantitative confirmatory and exploratory. The online survey, based on main environmental …

Agent-based modeling to address emerging threats from antimicrobial resistance to the sustainability of the beef industry
… in feedlot cattle. In the current thesis, an agent-based model (ABM) was developed under the context of emergence and transmission of AMR within and between feedlot cattle. The objectives of the first experiment were to investigate the influence of on-arrival injectable metaphylaxis options on …

A complex, high-performance agent-based model used to explore tuberculosis and COVID-19 case-finding interventions
… on TB incidence and mortality. We developed an agent-based model (ABM) called ABM Spaces and used it to ask: (i) What is the impact of four different TB case-finding interventions on TB detection rates, incidence and mortality? (ii) What is the impact of test frequency and test sensitivity on …

Widening stakeholder involvement: exploiting interactive 3D visualisation and protocol buffers in geo-computing
… user interaction whilst other tools demonstrate model environments with a tightly coupled user interface, resulting in poor performance. The research and development described herein relates to the development and testing of a visualisation engine for rendering the output of an Agent Based Model …

A computational approach to understanding spatial and temporal granularities in agent-based modeling
Epidemic agent-based models simulate individuals in artificial societies capable of moving, interacting, and transmitting disease amongst themselves. Due to limitations in data and computation, epidemic models simulating tens of millions of individuals often coarsen the finest representations of …

System importance measures: A new approach to resilient systems-of-systems
… on where and how resources need to be targeted. Based on the needs of an SoS, decision-makers can iterate through the design process to identify a set of practical and effective design improvements. ^ We use two case studies to demonstrate how the SIM-based design process can inform …

Integrated or monofunctional landscapes? Agent-based modelling for evaluating the socioeconomic implications of land use interventions
… they seek to reconcile. Using a Companion Modelling approach, which comprises the development of a role-playing game (RPG) and an agent-based model (ABM), this thesis addressed these caveats. The research was based in the Nilgiris of Western Ghats India, a tropical agricultural system at …

The potential of antimicrobial resistance diagnostics to inform prudent antimicrobial use in feedlot cattle: dynamic models as tools for optimizing interventions in bovine respiratory disease
… There is growing interest in the use of dynamic models to explore hypotheses about the relationships between AMU and AMR in animal populations. Dynamic models are mathematical representations of complex, time-varying systems and have been used to optimize intervention strategies in other food …
