Task analysis is a foundational step preceding both qualitative and quantitative assessments of human errors. A classification of generic task types (GTTs) help to standardize the process of task analysis and reduce the variability of task analysis results. In this study, a GTT classification in digitalized NPP main control rooms for human reliability analysis were established through analysis of 26 representative operating tasks. Ultimately 11 GTTs were identified and presented, along with definition and typical activities. By breaking down a complete operating task into a series of GTTs, analysts can quickly identify the corresponding activities, and then proceed with human error analysis.

摘要

Task analysis is a foundational step preceding both qualitative and quantitative assessments of human errors. A classification of generic task types (GTTs) help to standardize the process of task analysis and reduce the variability of task analysis results. In this study, a GTT classification in digitalized NPP main control rooms for human reliability analysis were established through analysis of 26 representative operating tasks. Ultimately 11 GTTs were identified and presented, along with definition and typical activities. By breaking down a complete operating task into a series of GTTs, analysts can quickly identify the corresponding activities, and then proceed with human error analysis.
