Archaeological Simulation: Comprehensive Methods & Application Guide

Introduction: Understanding the Past Through Simulation

Archaeological simulation involves creating models that replicate past processes, systems, and human behaviors to test hypotheses, explore scenarios, and gain insights that traditional archaeological methods alone cannot provide. By combining archaeological data with computational approaches, simulations allow archaeologists to explore dynamic interactions, temporal processes, and complex systems from the past. These techniques bridge gaps in the archaeological record, helping researchers understand not just what existed, but how and why past societies functioned as they did.

Core Simulation Principles

Types of Archaeological Simulations

Agent-Based Models (ABM)

• Simulate individual actors (people, households) making decisions
• Model emergent social patterns from individual behaviors
• Test theories about social organization and cultural change
• Explore adaptation strategies and decision-making processes

System Dynamics Models

• Focus on feedback loops and system-level interactions
• Model resource flows, population dynamics, and environmental change
• Examine long-term trends and stability of systems
• Analyze relationships between variables over time

Cellular Automata

• Grid-based models where cells change based on neighbor states
• Effective for modeling spatial processes like settlement patterns
• Simulate landscape use and modification over time
• Model diffusion of technologies or cultural practices

GIS-Based Simulations

• Incorporate real-world spatial data into models
• Test hypotheses about spatial relationships and patterns
• Model movement costs, resource accessibility, and viewsheds
• Simulate environmental changes and their effects on settlements

Network Analysis Simulations

• Model connections between people, sites, or resources
• Simulate trade networks and information exchange
• Test theories about social organization and hierarchy
• Explore resilience of connection systems
