Ergonomics Issues Investigation of a Complex System Based on a Questionnaire Methodology

Subjective questionnaire surveys are one of the methodologies for identifying ergonomic issues. In response to previous shortcomings in survey comprehensiveness, user coverage, and in-depth data analysis, this study adopts a human-machine interaction framework to develop new questionnaires. A subjective survey was conducted among 24 individuals across different positions, yielding issues and suggestions related to operational control and other aspects of a specific complex system. This research offers fundamental data for the development of an ergonomic assessment index suite, as well as for subsequent design enhancements of complex systems.
