摘要
为了评价VDT(visual display terminal)作业引发的疲劳,根据多级模糊综合评价的要求和VDT作业引 发疲劳感的特点,从视觉疲劳、局部骨骼肌疲劳和精神疲劳3个方面设计了评价指标体系,建立了VDT作业疲 劳的二级模糊综合评价模型.实证研究表明该模型能够对VDT作业者的疲劳程度做出正确的评价.模型中有 关构造评判矩阵的信息可通过问卷调查的方式获得,效率高,成本低,且具有良好的可靠性.此模型便于现场应 用,为企事业单位在VDT作业管理中全面、客观、准确地评价作业者的疲劳程度提供了新方法.
In order to evaluate fatigue of VDT(visual display terminal) operators, an evaluation index system and a two-grade fuzzy synthetic evaluation model of VDT operators' fatigue are set up based on fuzzy mathematics theory and the fatigue characteristic of VDT operators. The case studies show the model is effective in evaluating VDT operators' fatigue. The data to build judgment matrix is obtained by questionnaire, which costs a little but is reliable. The two-grade fuzzy synthetic evaluation model of VDT operators' fatigue can be easily applied in companies to evaluate VDT operators' fatigue.
