The primary objective of this research project was to investigate models for monitoring and predicting subjective workload in the control of complex systems. Such models would enable systems to use workload levels to distribute tasks optimally in addition to identifying levels of workload which could lead to a serious breakdown in performance. In the aircraft-pilot system, for example, such cap...

Introduction: One of the factors influencing the behavior and performance of nurses at the workplace is the mental workload. It is the amount of mental effort that a person uses during doing his or her task. Objective: The current study aimed at evaluating the mental workload and its related factors in the Intensive Care Unit (ICU) affiliated to medical and educational centers of Guilan Univer...

The mental workload imposed by systems is important to their operation and usability. Consequently, researchers and practitioners need reliable, valid, and easy-to-administer methods for measuring mental workload. The ratio of perceived time to clock time appears to be such a method, yet mental workload has multiple dimensions of which the perceived time ratio has mainly been linked to the task...

Introduction: One of the most important factors affecting quality of work-life (QWL) is the workload in the form of mental and physical. The increased workload may reduce the level of performance of workers. Therefore, the present study aimed to evaluate the relation of the mental and physicalworkload with the QWLof workers in the foundry industry. Material and Methods: This cross-sectional st...

The author of this report provides an overview of mental workload theory and mental workload measurement. She also describes the development, application, and validation of the mental workload modeling tools developed by the Human Research and Engineering Directorate of the U.S. Army Research Laboratory (ARL). These ARL tools, VACP (visual, auditory, cognitive, psychomotor) option in the improv...

Mental workload is an important component in complex human-machine systems. The limited applicability of empirical workload measures produces the need for workload modeling and prediction methods. In the present study, a mental workload prediction model is built on the basis of attentional resource allocation and information processing to ensure pilots' accuracy and speed in understanding large...
