Fuzzy Comprehensive Evaluation of Human Work Efficiency in a High-Temperature Thermal-Radiation Environment

Work efficiency is not only related to objective cognitive performance, but it also closely subjective psychological feelings. The existing research mostly focuses on the human safety tolerance limit from physiological perspective, and there are few studies work efficiency. In order evaluate of humans in a high-temperature thermal-radiation environment, this paper proposes method personnel efficiencies evaluation based fuzzy comprehensive method. method, ability questionnaire data subjects environment were obtained by building platform, ergonomic status score (ESS) was calculated determine grade. results study indicate that job satisfaction has strong influence efficiencies. safe WBGT temperature threshold can be borne lower than single environment. decreased significantly with increase radiation temperature. When 300 °C (WBGT ? 33.2 °C), should stopped immediately ensure health personnel. provide reference for labor protection working environments.
