| Summary: | In order to identify and assess the vulnerability of the port logistics system itself, this paper further improves the methodology on the basis of previous studies by using the Deterministic Experimentation and Evaluation Laboratory (DEMATEL) and Interpretive Structural Modeling (ISM) methods to study the correlation between the vulnerability factors of the port logistics system, and the best-worst method (BWM) to identify the key vulnerability points of the system. The results of the study showed that in terms of the correlation between the factors, port consolidation capacity and average arrival time are the most direct factors affecting the vulnerability of the port logistics system, and the strength of government regulation and coordination and the level of port management are important indirect factors affecting the vulnerability of the port logistics system. This paper also found that port loading and unloading facilities and natural disasters are the main vulnerabilities affecting the port logistics system itself. Port enterprises should focus on reducing the vulnerability of the system by strengthening the above aspects. The model constructed in this paper can also be applied to future research on the resilience and sustainability of port logistics.
