Abstract
Factory workers spend a significant amount of time on their assigned workstations performing tasks that are repetitive in nature. These tasks are not only physically exhausting, but also impose bio-mechanical stresses on workers. Various ergonomic risk factors such as repetitive movements, awkward postures, static postures, excessive noise and vibrations, and extreme hot or cold temperatures can add to workers’ fatigue. Poorly designed workstations exacerbate these factors and can lead to various musculoskeletal disorders (MSDs) among workers such as muscle strains, carpal tunnel syndrome, tendonitis, lower back pain, etc. In this research, human modeling and simulation was used to recreate real life factory workers and their workstations in a virtual environment. Using the simulation software, the virtual workers were designated to perform similar tasks as in real life situations. The purpose of this study was to analyze ergonomic risk factors that can lead to musculoskeletal diseases and complications among workers. Using various ergonomics risk analysis tools in simulated environments, we collected data on a multitude of health hazards caused by the tasks performed and gained information that allowed us to adjust the workers’ positions and/or the positions of the work stations. The results led to better quality of work, while at the same time reducing the risk for joint and muscle strain. Strengths and weaknesses of human modeling and simulation in ergonomics risk analysis are also explored.
