Research on Comprehensive Quantitative Evaluation System of Occupational Stress of Civil Aviation Pilots

Abstract

Through theoretical analysis, expert survey and issuance of the questionnaire to all age civil aviation pilots this paper summarized several influential factors for occupational stress of civil aviation pilots and established an occupational stress risk comprehensive valuating index system. According to the comprehensive analysis of occupational stress influential factors we took 7 factors, i. e. working load factor, physiological factor, organization factor, psychological factor, environmental factor, equipment factor and incident factor as the criterion. Then an occupational stress risk comprehensive valuating index system was established. Order relation analysis method (G1 method) was used to calculate the weights of indexes. Thus occupational stress risk three grade comprehensive evaluation index system was established. To quantify the level occupational stress index by four levels each occupational stress index was respectively corresponded to different degrees of occupational stress. Civil aviation pilots occupational stress questionnaires are compiled according to the comprehensive evaluation index system. Through the questionnaire statistical analysis results of occupational stress index distribution value interval of occupational stress index corresponding to the degree of occupational stress for civil aviation pilots was divided reasonably which reflected the comprehensive quantitative evaluation of occupational stress. The results showed that the quantitative evaluation system provided a practical way for the evaluation of occupational stress level and risk for civil aviation pilots.
