The Evaluation of Operator's Mental Workload in Operation Control Center Division in the Railway Industry
Pages 202 - 207
Abstract
The operation control center (OCC) in the railway industry is an automated-based work system controlled by the operators. The mental workload in OCC is necessary to evaluate due to a dynamic workload. The operators' mental workload was classified into mental underload conditions because of a long working hour with simple and repetitive tasks demand. This research was conducted with 17 male operators within two hours of peak sessions in the morning and afternoon shifts. The operators were performed a single and dual-task workload using EEG to find the optimal workload. NASA-TLX was chosen as a subjective assessment to measure mental workload. ANN was used to predict the operator's mental workload. The result shows significant differences between two different workloads and an increase of theta waves in frontal lobes. The ANN result claims 96.65% from the R-square value of the Testing data set were accurate to predict mental workload. The precise high accuracy level means that dual-task can be implemented in the OCC division to improve operators' workload and reduce monotonous activity.
