In this paper, we present an extension to the TSALB problem (Time and Space constrained Assembly Line Balancing) with ergonomic risk restrictions. This ergonomic risk is defined from the task durations and their categories regarding to the risk factor for the workers. A study is presented through a case linked to an engine assembly line in the Automobile industry, considering variable demand.

This discussion panel aims to identify ergonomic concerns, solutions and research needs, physical stresses, and outcomes related to clinical and surgical procedures. This session will begin with formal presentations to demonstrate current ergonomic concerns and research initiatives associated with clinical and surgical procedures to frame the panel discussion for the second part of the session....

Introduction Dental practitioners are exposed to different occupational hazards during the course of their professional activity, such as physical, chemical, biological, ergonomic factors. The ergonomic hazards, caused by strained posture and prolonged repetitive movements, can induce musculoskeletal disorders. It occurs in 54-93% of dental professionals and involve the spine, shoulder and hand...

Nacrtak A comparison of the ergonomic performance of 13 harvesting machine models was assessed from an ergonomic viewpoint. The main objective of the study was to compare ergonomic performance to harvesting machine operators’ work and propose viable solutions to improve the work environment. The principal assessed ergonomic requirements were operators’ workspace, operators’ seats, visibility, w...

Behaviour patterns specific to children pose them at greater risk of environmental hazards than adults. Ergonomics is the science of matching human interaction with the proximate environment. Conventionally ergonomic principles were applied on adult work places to ensure safety of the working environment. With emerging scientific evidence, school environments are being a focus to apply ergonomi...

A wide variety of observational methods have been developed to evaluate the ergonomic workloads in manufacturing. However, the precision and accuracy of these methods remain a subject of debate. The aims of this study were to develop biomechanical methods to evaluate ergonomic workloads and to compare them with observational methods. Two observational methods, i.e. SCANIA Ergonomic Standard (SE...

This study aimed to perform an ergonomic analysis in a fiberglass parts factory. For this purpose, was used the methodology of Ergonomic Work Analysis (EWA). At the end of the study it was possible to identify some ways to the development of improvements in order to contribute to the transformation of working conditions in the sector analyzed.
