The human body is susceptible to heat diseases when exposed to high temperature and high humidity for a long period of time. In order to assess the level of human heat stress in indoor high temperature and high humidity environments, the paper utilized the EWM to determine the weights of measurement parameters such as Mean Skin Temperature (MST), Heart Rate (HR), Oral Temperature (OT) and Tympanic Temperature (TT). A new comprehensive evaluation index QI was established based on VIKOR model. The reasonableness of QI was validated by fitting with the subjective parameters and the environmental parameters. The grading of QI was determined by improving the thermal stress intensity grading of the physiological stress indicator PHSI. The results show that the weight ranges of TT, MST, OT and HR are 0.151 9-0.421 1, 0.193 5-0.345 2, 0.160 4-0.426 9 and 0.134 8-0.339 1, respectively. MST has a high mean value of weight, which is greatly affected by environmental factors and labor factors. QI's safety range [0,0.36), thermal tolerance range [0.36,0.57] and hazardous range (0.57,1].
