Application Of The Agent Based Model To Predict And Study The

This research explores the application of agent-based models (ABMs) to predict and analyze the impacts of pandemics on supply chain management. The study aims to understand how changing dynamics during health crises influence supply chain resilience, decision-making, and logistical strategies through simulation techniques inherent to ABMs. As global interconnectedness increases, the importance of modeling complex adaptive systems such as supply chains during pandemics has grown, demanding sophisticated analytical tools for better preparedness and response strategies.

The paper begins by articulating the problem within the context of recent global health emergencies, emphasizing uncertainties and vulnerabilities in supply chains exacerbated by pandemics. It then formulates guiding research questions and hypotheses, such as “How can ABMs simulate behavioral responses of supply chain actors during pandemics?” and “What factors significantly influence supply chain resilience in pandemic scenarios?” The assumptions underpinning the model development are clarified, including the behavior of agents and the environmental variables considered. Delimitations are defined to focus on specific sectors or geographic regions, while limitations acknowledge potential constraints in data availability and model complexity.

The significance of this study lies in its potential to aid policymakers and supply chain managers by providing insights derived from simulation outcomes, facilitating better contingency planning. The review of existing literature covers key themes such as the application of ABMs in supply chain resilience, the impacts of pandemics on global logistics, and the integration of behavioral modeling with supply chain analysis. Based on these insights, the research proposal outlines a systematic approach, including model development, data collection, validation procedures, and a proposed timeline for execution, thus guiding future research efforts.

Introduction

In recent years, the world has witnessed several pandemics that have significantly disrupted global supply chains. Events such as the COVID-19 pandemic exposed vulnerabilities in supply chain resilience, emphasizing the need for effective predictive tools that can simulate complex interactions among various actors during health crises. Agent-based modeling (ABM) offers a promising approach for understanding these complexities by representing individual agents with specific behaviors and interactions, thereby capturing emergent phenomena within supply networks under pandemic conditions.

Problem Statement and Its Setting

The primary problem addressed in this research is the lack of comprehensive models capable of simulating the dynamic responses of supply chain actors during pandemics. Traditional analytical methods often fail to account for the adaptive behaviors and decentralized decision-making that characterize real-world supply chains. During pandemics, factors such as workforce shortages, transportation disruptions, and changes in consumer demand become complex, nonlinear, and difficult to predict accurately. These challenges necessitate innovative modeling approaches like ABMs, which can incorporate heterogeneous agent behaviors and simulate emergent patterns in supply chain performance. Existing literature indicates a gap in applying ABMs specifically to pandemic scenarios in supply chain management, highlighting an opportunity for contribution (Tikhomirov & Mantes, 2020; Zhang et al., 2021).

Hypotheses and Guiding Questions

• H1: Agent-based models can accurately simulate the behavioral responses of supply chain actors during pandemics.
• H2: The resilience of supply chains during pandemics is significantly influenced by policy interventions modeled within the ABM framework.
• Guiding Questions:
• What are the critical behavioral factors impacting supply chain performance during pandemics?
• How do different mitigation strategies affect supply chain adaptability in agent-based simulations?

Assumptions

• Agents in the model have rational behavior based on available information, similar to real-world decision makers.
• The environmental variables such as infection rates, government policies, and resource availability are accurately represented in the model parameters.
• The supply chain network under study is sufficiently representative to generalize findings to similar contexts.

Delimitations and Limitations

• The study focuses on specific sectors such as pharmaceuticals and consumer goods within North America.
• The model assumes homogeneous agent behaviors within actor categories, which may oversimplify real-world heterogeneity.
• Data limitations restrict the scope of real-time or highly localized modeling.
• Limitations include potential oversights of external factors such as geopolitical events or future technological developments.

Importance of the Study

This research contributes to the field of supply chain resilience by providing a dynamic simulation tool that captures behavioral responses during pandemics. The insights gained can assist policymakers and industry leaders in designing more robust supply networks and contingency plans, ultimately mitigating the adverse impacts of future health crises. Furthermore, the integration of ABMs into pandemic-related supply chain analysis advances theoretical understanding and offers a methodological foundation for subsequent empirical research.

Review of the Literature

Recent studies highlight the growing application of ABMs to analyze supply chain resilience. For instance, Lee and Lee (2019) demonstrated how agent-based simulations can model stakeholder behaviors and logistical disruptions during crises. Similarly, research by Chen et al. (2020) emphasized the importance of behavioral dynamics in supply chain adaptability, especially when faced with uncertainties like pandemics. The literature also explores hybrid models combining ABMs with other techniques such as system dynamics and network analysis to better capture complex phenomena (Sarkis et al., 2021). Moreover, studies underscore the necessity of incorporating behavioral factors, such as risk perception and decision-making heuristics, to enhance the realism of simulations (Miller et al., 2021). Despite these advances, there remains a research gap in applying purely ABM-based frameworks specifically tailored to pandemic-induced disruptions.

Outline of the Proposed Study

• Week 1-3: Literature review and refinement of research questions.
• Week 4-6: Development of the conceptual ABM framework, identifying agent types and behaviors.
• Week 7-9: Data collection, including case studies and expert input to parameterize the model.
• Week 10-12: Implementation of the ABM using software such as AnyLogic or NetLogo.
• Week 13-15: Validation of the model through comparison with historical data and scenario analysis.
• Week 16-18: Analysis of simulation results, identification of key insights, and formulation of recommendations.
• Week 19-20: Final report writing, review, and dissemination of findings.

The project timeline emphasizes iterative model refinement and stakeholder engagement to ensure practical relevance and academic rigor.
