Abstract

Abstract: To improve the performance and reliability of VDT continuous operation , a break schedule was studied by carrying out experiments. A fatigue evaluation index system and mental arithmetic experiments were designed after analyzing operation characteristics. Membership functions of fatigue were put forward based on fuzzy statistics and minimum fuzzy entropy, and a fuzzy comprehensive evaluation model was built for getting the operation fatigue evaluation value of time inflection point. The results show that the fuzzy comprehensive evaluation model is suitable for human-computer interactive VDT continuous operation fatigue evaluation, and the self-adaptive break schedule is easy to operate and has little interference to the job.

Key words: visual display terminal(VDT), continuous operation, break, self-adaptive, fuzzy evaluation
