基于贝叶斯网络的VDT作业疲劳

摘要

VDT,as the representative of modern labor assignment ,can enhance the working efficiency and seriously affect the physical and mental health of the operators .A method of using Bayesian network is put forward to analyze fatigue , establishing fatigue prior Bayesian networks , and then the posterior Bayesian networks by examples .The model is analyzed to find the key factors by using Netica software while analy-zing factors causing fatigue .%在分析VDT作业中引起疲劳的各种影响因素时，提出利用贝叶斯网络分析疲劳的方法，建立疲劳先验贝叶斯网络，通过实证研究建立后验贝叶斯网络，利用Netica软件对后验贝叶斯网络模型进行数据分析解释及推理，以期找到影响疲劳的关键因素。
