A Study on Key Factors Affecting the Resilience of Emergency Logistics Supply Chains: A Hybrid Fuzzy DEMATEL-ISM-MICMAC Approach

Against the backdrop of global climate change, frequent public health crises, and escalating geopolitical conflicts, the stable operation of emergency logistics supply chains faces severe challenges. Building a resilient system that combines disturbance resistance and adaptability has become an urgent necessity. This paper, grounded in the evolution of resilience theory, clearly defines the meaning of emergency logistics supply chain resilience. It systematically identifies and constructs an indicator system comprising 17 influencing factors across four dimensions: Resistance, Responsiveness, Adaptability, and Development Capacity. Employing a hybrid fuzzy DEMATEL-ISM-MICMAC approach, the study quantifies causal relationships and hierarchical structures among factors while analyzing their driving forces and dependency attributes. Findings reveal that infrastructure development, emergency plan integrity, talent cultivation, financial safeguards, and regulatory support constitute core critical factors influencing emergency logistics supply chain resilience. Among these, regulatory support and financial safeguards form the fundamental pillars underpinning the system’s operation. The multidimensional influence factor framework and hybrid analytical method developed in this study not only enrich the theoretical research system on emergency logistics supply chain resilience but also provide scientific decision-making references and practical guidance for policymakers and industry practitioners to formulate targeted resilience enhancement strategies.
