Abstract

Abstract: In order to analyze the factors affecting the human reliability of high-speed railway dispatchers in-depth, the PSF for high-speed railway dispatchers were extracted based on literature review, task analysis and structured interview. The PSF weights were calculated by using analytic network process (ANP) method. According to the PSF, a questionnaire was designed and the PSF implementation degrees were achieved by the survey results. Then the critical PSF were extracted by using the improved PEM method. The results show that complex event cognitive level, workload, operation skills are the top three factors of importance degree,that labor organization and scheduling, workload, safety information reporting and feedback are the last three factors of implementation degree,and that workload complex event cognitive level, safety information reporting and feedback are the critical factors.

Key words: high-speed railway, dispatcher, human reliability, performance evaluation matrix(PEM), performance shaping factors(PSF)
