Identifying Critical Nodes in Airport Risk Networks
An Adaptive PageRank Approach under Dynamic Scenarios
This paper introduces an adaptive PageRank algorithm to identify critical nodes in airport risk networks under dynamic scenarios. It combines a weighted complex network model with mechanisms for dynamic weight adjustment based on operational criticality and scenario-driven threats. Validated with airport incident data, the approach reveals small-world characteristics, identifies core cascading chains, and shows communication disruption nodes surging in influence under simulated dynamic scenarios, a critical shift undetected by static methods. This advances risk management from static analysis to dynamic resilience.
Our solution provides a sophisticated tool for dynamic risk management in complex, high-risk environments. By identifying evolving critical nodes and propagation pathways in real-time, it enables proactive, resilience-oriented defense strategies, moving beyond static risk assessments to anticipate and mitigate cascading failures, optimize resource allocation, and enhance overall system performance and safety under dynamic, high-stress conditions.

Adaptive PageRank Algorithm
The core of this research is an adaptive PageRank algorithm designed to identify critical nodes under dynamic high-pressure conditions. It integrates a weighted complex network model with two key mechanisms: (1) a specific weight calibration mechanism based on control zone operational criticality, dynamically adjusting node priorities; (2) a scenario-driven dynamic adjustment mechanism, enabling real-time modification of edge weights to simulate evolving threats. This allows for real-time assessment of node importance under changing circumstances, moving beyond traditional static analyses.

Dynamic Risk Propagation
The study demonstrates how risks propagate rapidly through specific airfield systems, often through cascading chains like 'control-execution-support'. Under simulated dynamic scenarios, nodes representing communication disruptions (E-class electronic countermeasures) exhibit a significant surge in influence rankings (average 53%). This highlights the shift from static, human-error-centric risks to dynamic, information-system-failure-driven vulnerabilities under adversarial conditions.

Static vs. Dynamic Risk Management
Traditional static risk models (e.g., collision risk models, N-K models) are insufficient for capturing the cascading propagation characteristics of risks in complex, high-stress military aviation systems. This research proposes a dynamic, resilience-oriented defense mechanism embedded with OODA-loop capabilities, moving beyond static prevention to active response.

Case Study & Real-World Applicability
The model was validated using an airport incident report dataset and retrospectively tested against a 2023 runway incursion event. It successfully identified critical nodes and the highest-probability risk path (C₁→B7→A4), a conclusion corroborated by the official investigation. The model exhibits linear computational complexity, allowing for efficient processing of large-scale infrastructure analysis.
WH Airport: Runway Incursion Analysis
The adaptive PageRank model was applied to WH Airport data, identifying 'Vehicle Runway Incursion' (A4) as a critical node and C₁→B7→A4 as the highest-probability risk path. This finding was later corroborated by official investigation reports, demonstrating the model's predictive accuracy and practical relevance.
