Analysis of Factors Affecting the Vulnerability of the Hazardous Materials Transportation System

A method for identifying key vulnerability factors in hazardous materials transportation systems is proposed, combining qualitative and quantitative analytical techniques. First, we establish a conceptual framework that Integrates definitions of hazardous materials, their transportation systems, and vulnerability (including supply chain vulnerability). Through qualitative analysis, we identify critical factors that contribute to systemic vulnerability. Subsequently, the interrelationships among these factors are quantified using the Decision-Making Trial and Evaluation Laboratory (DEMATEL) method. By applying DEMATEL, we model causal relationships and prioritize key factors based on centrality and causality indices. Finally, we proposed targeted mitigation measures aligned with these prioritized factors to enhance the resilience of hazardous materials transportation systems.
