introduction: work pressure and excessive workload can jeopardize and impair the people’s health. one of these impairments is musculoskeletal disorders. among these disorders, low back pain is the most common and most costly problem. the purpose of this study was to investigate the relationship between workload and prevalence of low back pain in assembly line workers of a car manufacturing fact...

This paper address a special class of generalized assembly line balancing in which it is assumed that there are two groups of workers: skilled and unskilled ones. The skilled workers are hired permanently while the unskilled ones can be hired temporarily in order to meet the seasonal demands. It is also assumed that more than one worker may be assigned to each workstation. To show the adv...

the aim of this study was to evaluate the effectiveness of individual-focused stress management training namely deep breathing exercise (dbe) on self-perceived occupational stress among male automotive assembly-line workers.a quasi-experimental study was conducted at 2 automotive assembly plants in malaysia over 9 months, from january 2012 to september 2012. assembly-line workers from plant a r...

background; work-related musculoskeletal disorders (wmsds) may involve all parts of the body, and have been a worldwide problem. employed women are two to five times more likely to report such problems, and assembly lines suspected to induce more wmsds because of high rate of repetitive motions. methods;the aim of this study to determine the prevalence of wmsds in women workers of an automobile...

BACKGROUND Carpal tunnel syndrome (CTS) is a common occupational disorder associated with repetitive manual work. Little information exists about the possible relation between the variation of biomechanical hand/wrist exposure and the development of symptoms and median nerve conduction values. AIMS To investigate the prevalence of CTS in a group of workers exposed to intensive use of the hand...

with the growth in customers’ demand diversification, mixed-model u-lines (mmul) have acquired increasing importance in the area of assembly systems. there are generally two different approaches in the literature for balancing such systems. some researchers believe that since the types of models can be very diverse, a balancing approach without simultaneously sequencing of models will not yield...

Background: Work-related musculoskeletal disorders (WMSDs) may involve all parts of the body, and have been a worldwide problem. Employed women are two to five times more likely to report such problems, and assembly lines suspected to induce more WMSDs because of high rate of repetitive motions. Methods: The aim of this study to determine the prevalence of WMSDs in women workers of an automobi...

We propose the Assembly Line Worker Integration and Balancing Problem (ALWIBP), a new assembly line balancing problem arising in lines with conventional and disabled workers. The goal of this problem is to maintain high productivity levels by minimizing the number of workstations needed to reach a given output, while including in the assembly line a number of disabled workers. This problem gain...
