Abstract: Vessel traffic controllers work around the clock in order to fulfil the needs of international shipping traffic in each harbour. Due to their special work arrangement, shift work could have serious consequences on their health. Fatigue is one of them and could affect the outcome of the controller's work. For management to better schedule the controller's tasks, factors that have a bearing on the controller's fatigue need to be investigated. A structural equation model was carried out to conduct a path analysis. The relationship among physical fatigue (PF) and mental fatigue (MF), before and after work shifts, was then identified. The results show that sleeping quality has direct influences on the controller's fatigue before duty, either PF or MF. In addition, PF after shifts is influenced by sleeping quality, working environment, workload, PF before shifts, and MF after shifts. The MF after shifts is mainly affected by sleeping quality, workload and MF before shifts. The results indicate that workload and sleeping quality bear strong relations to the causes of fatigue. These findings are useful for management to reduce the level of controllers' fatigue and to improve harbour safety.
