Welding workstation worker operation fatigue comprehensive evaluation and analysis method based on combined empowerment-cloud model

The invention relates to a welding workstation worker operation fatigue comprehensive evaluation and analysis method based on a combined weighting-cloud model, and the method comprises the following steps: analyzing the fatigue factors of an automobile seat skeleton welding workstation worker, and constructing an automobile seat skeleton welding workstation worker fatigue evaluation system from the physiological and psychological fatigue aspects. The weight of each factor is calculated in combination with fuzzy AHP-DEMATEL combined weighting, a cloud model comprehensive evaluation method is adopted, the subjective influence of fatigue evaluation is reduced, and the fatigue grade of the welding workstation workers is determined. The method is simple and practical, the fatigue of people in work is accurately quantified, the fatigue index calculation precision is improved, and a scientific basis is provided for evaluating the working fatigue degree of workers. 本发明涉及一种基于组合赋权-云模型的焊接工作站工人作业疲劳度综合评估分析方法，包括如下步骤：分析汽车座椅
