Research on Fuzzy Comprehensive Evaluation of Fire Safety Risk of Battery Pack Production Process Based on DEMATEL-ANP Method

A new safety risk assessment model for battery pack production processes was developed using the DEMATEL-ANP method to analyze the impact and complex relationships of risk-influencing factors. Initially, five major risk-influencing factors were identified, leading to the construction of a 15-factor indicator system. Through the DEMATEL method, these factors were categorized into cause and result factors. Subsequently, by combining the DEMATEL and ANP methods, key risk-influencing factors were identified by comparing ANP weights with hybrid weights adjusted through the DEMATEL-ANP method. Finally, integrating the DEMATEL-ANP method with the fuzzy comprehensive evaluation method allowed us to assess the overall fire safety risk level. Our findings highlighted “hazards in the test process” and “fire hazards” as critical risk factors needing control and elimination in the highly hazardous battery pack production process. This method offers dynamic evaluation and valuable insights for safety management in battery pack production.
