복합 물류 공정에서 가상 시나리오 기반 안전 작업 모델 개발 및 위험성 평가

To effectively identify new risks in complex logistics processes, it is essential to consider not only individual equipment but also the interactions between systems and workers. However, current international safety standards have limitations in addressing the complex risks that arise from these interactions. In this study, the user error-based scenario development process described in KS P IEC 62366-1 was applied to six logistics processes in an electronics manufacturing environment. Task safety scenarios were developed to reflect both routine operations and potential human- or system-related errors. A risk assessment conducted in accordance with ISO/TR 14121-2 initially identified 13 high-risk and 11 medium-risk items. After the implementation of scenario-based safety improvements, all identified risks were reduced to an acceptable low-risk level (Level 1-2). The analysis revealed previously unrecognized hazards, including interference between autonomous mobile robots (AMRs) and fire shutters, as well as unauthorized access to forklift operating zones. These findings demonstrate the practical utility of a scenario-based approach in enhancing intrinsic safety and reducing risks in complex, automated industrial environments.
