Abstract In order to promote the development of the social management mechanism on human working fatigue, and prevent the economic loss from working fatigue, it is necessary to make a quantitative evaluation on human working fatigue. First, based on the combination of entropy method, factor analysis method and comprehensive index method, this paper evaluates four fatigue indexes through questionnaires and experiments. Second, by using the improved fuzzy Borda method, this paper makes the combination evaluation of the results from the three comprehensive evaluation methods above. Finally, this paper draws the conclusion that, based on the result of the cluster analysis, the enterprise could improve its working tasks, incentive measures and working condition to reduce working fatigue. Keywords Combination evaluation • Human factors engineering • Improved fuzzy Borda method • Working fatigue
3.1 Introduction With the speeding up of economic development, people feel their life is becoming more and more stressful despite their material success. An increasing number of employees are affected by working fatigue which may jeopardize physical and mental health. A study points out that the working fatigue has been developed to a universal problem which would bring about social crisis. Besides, the study also puts forward the strategic planning to establish a perfect social crisis management system

of fatigue (Guo Xianhong and Chen Xian 2008). Working fatigue is a systematic problem including complex factors. One of the most important task is to solve the problem that how to make it more reasonable to evaluate the working fatigue of the employees. At present, the study of fatigue is mainly focus on the concept of fatigue, the theoretical model and influence factors (Zhan Fashang 2006). There is no method that can make a direct determination of fatigue (Qi Jiyan 2011). The evaluation of fatigue can be divided into three aspects, forecast beforehand, monitor during the process and evaluate after the event. Based on the decomposition of movement and the body’s energy analysis, forecast beforehand focuses on estimation and simulation (Wang Xiangyin et al. 2010; Wang Wei et al. 2006). Besides, it evaluates fatigue model through the theoretical analysis (Gao Yongquan 2007); Monitor during the process mainly focuses on monitor fatigue through the physical and mental changes (Kang Weiyong et al. 2007) and how to provide real-time fatigue feedback and alert by using various fatigue monitoring device (Qi Jiyan 2011; Jin
