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,

    The use of fixed position layout becomes indispensible in the situations where other types of layouts are inappropriate. For instance, in the construction of oil rigs, the functional layout would not be appropriate layout where different parts of the product are manufactured in different departments, then shifted and compiled in another department (Miltenburg, 2005). On the other hand in fixed position layout, all the required equipments and labor are essentially moved to the site in each step of job performance. Similarly,…

    An Ergonomic Assessment is an examination of the injured workers’ workstation; focusing on posture, keyboard use, physical work demands, environmental factors as well as the equipment and workplace design (RehabManagement, 2013). Through this assessment the OT can support the successful return to work of Ms Blogs by ensuring her workplace is designed to minimise any discomfort or aggravation whilst she recovers from her injury (Lahmi, Shahnavaz, & Jazani, 2004). By implementing these ergonomic principles it helps to “prevent injury, re-occurrence of injury and increases productivity” (RehabManagement, 2013).…

    Ergonomics is the scientific, interdisciplinary study of individuals and their physical relationship to their environment. Ergonomics can be further defined as "the design of the workplace, equipment, machine, tool, product, environment, and system, taking into consideration human's physical, physiological, biomechanical, and psychological capabilities. Ergonomic design is the application of this body of knowledge to the design of tools, machines, systems, tasks, jobs, and environments for safe, comfortable and effective human use. The term ergonomics is derived from the Greek word ergos meaning "work" and nomos meaning "natural laws of" or "study of." In the United States, the term 'human factors engineering' is often used.…

    The first problem we discussed is the number of tasks per assembly line. We see this as a problem because this isn’t how an assembly line should be. The essence of an assembly line is that at every station a simple task is done. Maybe two but it has to stay a simple action. This ensures a smooth flow of the production process. What you see at this assembly line is that there are three positions where one operator has to fulfil multiple tasks. This does not enhance the efficiency because the operator has to switch every time he finishes a single task. A solution for this problem is to implement more assembly line positions. This will result in a smoother and more efficient flow of the production. In a situation like that every operator has to do only one or two tasks instead of six. This is beneficial because when you look at the production of a car for instance. If you let one employer built one entire car it will…
