This paper addresses the design of an assembly system facility consisting of multiple assembly lines of different shapes. In such a design problem there are two conflicting objectives: (i) to minimize the overall area of the facility; and (ii) to maximize the efficiency of the material handling transportation system. We first address the optimization problem of objective (ii) when replacing obj...

It is apparent that severe weather should hamper the productivity of work that occurs outside. But what is the effect of extreme rain, snow, heat and wind on work that occurs indoors, such as the production of automobiles? Using weekly production data from 64 automobile plants in the United States over a ten-year period, we find that adverse weather conditions lead to a significant reduction in...

Intelligent assist devices (IADs) are a new class of hybrid devices for direct, physical, interaction with a human operator in shared workspaces. These devices – designed for the assembly line worker – can reduce ergonomics concerns that arise due to on-the-job physical and cognitive loading, while improving safety, quality and productivity. Cobots, a sub-set of IADs, implement software defined...

welding is one of the key components of numerous manufacturing industries, which has potential physical and chemical health hazards. many components of welding fumes can potentially affect the lung function. this study investigates the effects of welding fumes on lung function and respiratory symptoms among welders of an automobile manufacturing plant in iran. this historical cohort study asses...
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...

A systematic approach is presented to obtain improved panel tit quality through the use of an optimum panel fitting strategy. ‘The objective of the optimal1 panel fitting strategy is to determine the location of the panels on the automobile body such that the gap and flush variation of the panel fit are mmimized. This approach uses measurement data from both the panels and the body-inwhite (BIW...

The painting process is an important part of the entire automobile manufacturing system. Changing color in the painting process is expensive because of the wasted paint and solvent during color change. By intelligently selecting cars toward downstream operations at the places where conveyors converge or diverge, we can reduce the number of such color changes without additional hardware investme...

Spot welding is a type of resistance welding in which pieces of metals are pressed together and an electric current is passed through them. Spot welders are at risk of contact with some potentially hazardous agents but there are few studies about the respiratory effects of spot welding.
Our objective was to study lung function and respiratory symptoms among spot welders and of...
