철도종사자 인적오류 평가 시스템 설계 = Design of Human Error Evaluation System for Railway Workers

국문 초록 (Abstract)

철도는 기계적, 환경적, 인적 원인 등 다양한 원인으로 사고가 발생하게 된다. 인적오류 분석의 어려움으로 인해 철도 사고를 예방하기 위한 연구는 기계적, 환경적 분야에 집중되었다. 또한, 철도 사고에서 기계적, 환경적 원인에 의한 사고는 인적 원인에 의한 사고와 연결되어 있다. 본 연구에서는 철도 운영에서 인간의 역할과 관련된 안전성을 향상하기 위해 철도종사자의 인적오류를 평가하는 시스템을 설계한다. 철도종사자의 직무분석을 바탕으로 인적오류를 평가하고 인적오류를 사전에 예측 및 예방할 수 있는 시스템을 개발한다. 이를 위해 인적오류 평가 시스템은 직무분석, 직무수행 영향인자 정량화, 인적오류 평가 모듈을 개발한다. 각 모듈에 대한 역할을 명확히 하기 위하여 모듈 내 기능을 정의하고 기능의 주요 작업에 관해 설명한다. 또한, 모듈 내에 각 데이터 간의 관계를 분석 및 정리하여 나타낸다. 이러한 3가지 모듈은 철도기관별 직무 특성을 반영하여 정보를 입력하고 철도종사자의 인적오류를 평가할 수 있다. 철도종사자 인적오류 평가 시스템은 인적 사고를 예방하고, 관리하는 데 중요한 역할을 할 것으로 판단된다.

다국어 초록 (Multilingual Abstract)

Railroad accidents arise from mechanical, environmental, and human factors. On the other hand, research on accident prevention has often focused on mechanical and environmental causes because of the difficulty of analyzing human error, even though these frequently intersect with human factors. This study aims to improve safety in railway operations by designing a system to assess and predict human error among railway workers. This system, based on job analysis, includes modules for analyzing the job roles, quantifying the job performance influencing factors, and evaluating human error. Each module was structured with specific functions and primary tasks, detailing the relationships among the data within the module. The system allows for customized data input and accurate human error evaluation by adapting to the distinct job characteristics of each railway organization. This human error evaluation system is expected to play a critical role in preventing and managing accidents associated with human error in railway contexts.
