基于G1法的高危作业疲劳风险模糊综合评判

Fatigue risk fuzzy evaluation for high-risk operations based on G1 method

疲劳严重威胁作业安全,许多事故都直接或间接由疲劳引发。针对高危作业疲劳风险评价问题,考虑作业疲劳致因,综合运用G1法,提出高危作业疲劳风险的模糊综合评判方法。首先,根据疲劳的表现,系统分析影响高危作业疲劳的因素,以管理因素、岗位因素、作业环境、生理、心理等5个因素为准则,构建作业疲劳风险的评价指标体系。然后,应用G1法,确定指标权重,建立高危作业疲劳风险多级模糊综合评价模型,评判疲劳状况。最后,通过一个案例验证了模型方法的可行性与有效性,为综合评判高危作业疲劳发生可能性提供了一个新视角与方法。

Fatigue is the direct or indirect cause of many accidents and is a serious threat to work safety .For fatigue risk evaluation of high-risk operations , the causes of operations fatigue were considered and a fuzzy comprehensive evaluation method was proposed according to comprehensive application of G 1.First of all, a systematical analysis of the influencing factor was conducted based on the performance of fatigue , and an evaluation index system was constructed with criterion of management , job, environment, physiological and psychological factors . Then, the weights of indexes were determined by applying the method of G1 and the multilevel fuzzy comprehensive evaluation model of high-risk operations fatigue risk was built to judge fatigue .Finally , the feasibility and effectiveness of the method were illustrated by an example .It provides a new perspective and tool for the comprehensive e-valuation on the likelihood of high-risk operations fatigue .
