A Simulation Study on the Safety Operation Capacity of Tower Crane Systems from a Resilience Perspective

To effectively enhance the safety operation capacity of tower crane systems, this study first establishes an evaluation index system based on prior field investigations. A system dynamics model is then constructed by identifying the causal relationships among influencing factors. Using expert scoring methods, both single and combined strategies for improving safety operation capacity are formulated. These strategies are simulated using Vensim software to examine their impact. The simulation results indicate that under single strategies, the contributions to safety operation capacity are ranked as follows: personnel safety skills and competence (9.7%) > safety education and training (8.95%) > technological innovation and application (7.6%) > deployment of intelligent tower crane systems (5.25%). Under combined strategies, the effect paths are ranked as: Path 1 (18.15%) > Path 2 (17.83%) > Path 3 (16.6%). This study offers new insights for enhancing the safety operation capacity of tower crane systems and reducing the occurrence of accidents.
