Abstract
This paper outlines the human error identification (HEI) techniques currently existent to assess and analyze latent human errors. Even if many formal error identification techniques have existed for years, few have been validated to cover latent human errors analysis in different domains. This study considers lots of possible error modes and influential factors that include external error modes, internal error modes, psychological error mechanisms and performance shaping factors, and integrates a number of execution procedures and frameworks of human error identification techniques, including hierarchical task analysis, task classification, error analysis, consequence analysis, reliability analysis and remedy analysis, to identify the latent human errors and to evaluate the human reliability in a case plant. The case study in this research is the operational process of changing chemical cylinder in the manufactory. In addition, the integrated HEI method is used to assess the operational processes and system reliability. It is concluded that the integrated method and analysis procedure is a valuable aid to develop much safer operational processes and can be used to predict human error rates of critical tasks in the plant.
