The Design and Realization of HRA Service System for the Engine Assembly

Abstract

Human error is a main factor causing the engine assembly quality defects. This paper presented the application of the Root Cause Retrospective Analysis (RCRA) of the Cognitive Reliability and Error Analysis Method (CREAM) in the engine assembly process, proposed a new model of the RCRA for engine assembly failure within the framework of HRA (Human Reliability Analysis) service system for the engine assembly. The application of the model was illustrated by an example. The research belongs to one of the core functions of HRA service system, which can be used to perform the human error analysis in the process of the engine assembly, so as to provide guidance for production.

A Human Error Analysis in Human–Robot Interaction Contexts: Evidence from an Empirical Study

“…Concerning the causes of errors, Torres et al highlighted that, during the execution of manual assembly tasks, some operations are the most likely to cause errors because the level of difficulty is very high [28]. In other cases, the main reason for the errors can be related to the poor skills of the operators or the adverse psychology, often due to the scarce confidence in the working environment or the lack of safety awareness [29]. The psychological factors which ledd to human errors have been widely debated in the literature, beginning from 1990, when the study of HRA started combining different areas of scientific studies, such as behavioral science and psychology [30].…”
