The paper presents the results of a research work regarding the effective design of an assembly line for heaters production. Considering that the real plant still doesn’t exist, simulation has been used as cognitive tool. After the modeling and the VV&A phases the simulation has been used for carrying out ergonomic analyses for each assembly line workstation. The simulation results highlight pr...

introduction: macro-ergonomics is an important factor that affects behavior, favorable performance and personnel’s efficiency that can cause conformity of employees by increasing labor and efficiency and in result decreasing employees’ stress amount. the aim of the present study was to investigate relationship between macro-ergonomics and occupational stress in employees working in one casting ...

This work addresses a balancing problem approach whose objective is to minimizing the ergonomic risk dispersion between the set of workstations of a mixed-model assembly line and the risk level of the workstation with the greatest hazard. A GRASP procedure is proposed to achieve these two challenges simultaneously. This new procedure is compared with two Mixed Integer Linear Programs, the MILP-...

This paper gives an overview of a participatory ergonomic intervention aimed at reducing low back pain cases in the dispatch department of a catalogue and e-commerce retail company. Based on the findings of the ergonomic analysis and design committee, the company's own employees redesigned the assembly line's layout. As a result of these changes two job tasks that involved manual material handl...

BACKGROUND Early intervention educators who serve children with special needs often suffer from physical strains. The objectives of this study were to investigate the prevalence of work-related musculoskeletal disorders in this population, and to evaluate the relationship between work-related musculoskeletal disorders and personal/ergonomic risk factors. METHODS A self-designed questionnaire ...

The main objective of this research was to conduct an assessment of ergonomic-related problems in oilrigs in a desert environment. A checklist, physical audit and medical records were used in the investigation. The results showed significant health, environment and work-related problems that could be attributed to ergonomic deficiencies in the work system of the oilrig. Some major ergonomic iss...

This article presents information about the development of the dissertation. Deals with the production of ergonomic diagnosis in the environments and work processes of an important center of research and development in Public Health, FIOCRUZ. Critically evaluates the performance of a team promoting and facilitating the process of implementing ergonomic changes suggested. Through analysis of doc...

OBJECTIVE The literature on psychosocial job factors and musculoskeletal pain is inconclusive in part due to insufficient control for confounding by biomechanical factors. The aim of this study was to investigate prospectively the independent effects of effort-reward imbalance (ERI) at work on regional musculoskeletal pain of the neck and upper extremities of call center operators after control...

background: in addition to individual problems and conditions, low back pain reduces working capacity, resulting in the waste of time and absence from the work, and increases healthcare costs and economic losses. this study aimed to determine the prevalence rate of low back pain and its relationship to demographic factors, body mass index, and education in ergonomic principles in rural men.   m...

results the total art score was equal to 30.07 ± 12.43. data analysis from art illustrated that 74.6% of 240 cases were in high and 13.8% were in medium level of risk. art-electre results revealed that grading and pars naghsh halls were in the best and decoration hall was in the worst ergonomic conditions and should be placed in the top priority of action level. background in this paper, the er...
