Modern manufacturing systems should satisfy emerging needs related to sustainable development. The design of sustainable manufacturing systems can be valuably supported by simulation, traditionally employed mainly for time and cost reduction. In this paper, a multi-purpose digital simulation approach is proposed to deal with sustainable manufacturing systems design through Discrete Event Simula...

The application of ergonomics in enterprises is gaining in importance. Nowadays ergonomics in enterprises is addressed in a more technical manner. Therefore it is necessary to try to adapt generally applicable ergonomic practices to a technical perception. The result of this is a search for approaches that can be used as a link between technical and ergonomic perspectives of problems in the wor...

We assessed the effects of two ergonomic aids on the usability of an in-line screwdriver. The simple aids considered were a hand support and a sleeve which softened the handle. In an experiment, 15 subjects drove screws into horizontal plywood plates with four combinations of a screwdriver and an ergonomic aid. The activities of four forearm muscles (EMG) and the force acting on the screw were ...

This paper introduces the Ergonomic Work Analysis as a relevant instrument to identify the risks in occupational environments through the investigation of factors that influence the relationship between the worker and the productive process. It draws a parallel between the several aspects of risk identification in traditional tools of Health and Safety Management and the factors embraced by the...

Methods The process used to collect postural, discomfort, and performance data pre-and post-implementation of split keyboard. Participants 80 employees participated in the study. The characteristics of the population are presented. The postural, discomfort, and performance outcome...

Ergonomic practice increases the productivity, quality, and longevity of the dermatologic surgeon. When used properly, magnification devices can be ergonomic and beneficial additions to the dermatologic surgeon's practice. Herein, we review the available magnification options for the dermatologic surgeon and evaluate the options based on cost, design, and functional advantages and disadvantages...

This review article outlines the physical, chemical, biological, ergonomic and psychosocial occupational health hazards of mining and associated metallurgical processes. Mining remains an important industrial sector in many parts of the world and although substantial progress has been made in the control of occupational health hazards, there remains room for further risk reduction. This applies...

BACKGROUND Both low back pain (LBP) and neck pain (NP) are major occupational health problems. In the workplace, participatory ergonomics (PE) is frequently used on musculoskeletal disorders. However, evidence on the effectiveness of PE to prevent LBP and NP obtained from randomised controlled trials (RCTs) is scarce. This study evaluates the process of the Stay@Work participatory ergonomics pr...

Human figure models are commonly used to facilitate ergonomic assessments of vehicle driver stations and other workplaces. One routine method of workstation assessment is to conduct a suite of ergonomic analyses using a family of boundary manikins, chosen to represent a range of anthropometric extremes on several dimensions. The suitability of the resulting analysis depends both on the methods ...

This paper presents a formal framework for the development of interactive software that bridges the gap between ergonomic knowledge and software design. It builds upon previous work on formal notations and proposes an integrated development process from requirements to model-based execution. It also embeds ergonomic knowledge in requirements, and proposes a way to formally represent them and to...
