Abstract— Ergonomics plays an important role in workers’ productivity. Workstation layout and work design are two major factors of ergonomics of worker’s efficiency. Now, manufacturers found that instead of investing lots of money on man, machine, material, method (4m),improving ergonomics of workplaces is cost saving. Ergonomics found great need when market demand is high and manufacturers need more output within short period. This study was conducted on assembly workstation of welding shop. Ergonomic study of this assembly workstation was done by using motion study. Observations were made by studying each element of motion film recorded by video recorder. Results from this study reveal that there is need to modify workstation layout according to ergonomic principles.
Keywords: Ergonomics, Motion film, Fatigue factors, Productivity, Workplace Layout
I. INTRODUCTION
For productivity improvement in manufacturing industries, efficiency of worker plays an important role .Productivity of worker greatly depends upon ergonomic design of workstation. Efficient ergonomics in workstation design shows better interaction between man-machine systems. Lot of research has been done on analysing and improving ergonomics of workstation, facility layout and tool design. Study regarding operator performance and comfort in repetitive assembly task has been done (Shikdar et al,
