摘要

Abstract

this study adopts the modeling framework of the SPA-ITFN safety assessment model and employs grounded theory to develop a comprehensive storage accident risk evaluation system. The system comprises five primary indicators (including inherent/aging risks of facilities/equipment and operational risks related to personnel behavior) and 18 secondary indicators (such as inherent shelf system risks and overload risks). A risk assessment model is constructed using pair-set analysis combined with interval triangular fuzzy number theory

where correlation coefficients balance determinism and uncertainty in risk metrics

while interval triangular fuzzy numbers clarify risk level boundaries. Case analysis of K Enterprise's supporting warehouse facilities in Weifang

Shandong Province reveals: a composite correlation coefficient of-0.1526 indicates moderate risk levels; combined values for cargo-related

load-related

and indirect impact risks reach-0.5833

classified as high-risk areas requiring prioritized mitigation. These findings demonstrate the robust applicability of our evaluation system and SPA-ITFN model

providing valuable references for precise accident risk assessment and prevention strategies in warehousing operations.
