Abstract
Problem statement: High demand for products in the manufacturing industry had driven the human workers to work faster and adapt to their un-ergonomically designed workstation. Some tasks at assembly workstations require human workers to stand for a prolonged period of time to assemble the products. Approach: This study was conducted at an automotive component manufacturer. Twenty full time workers working at the assembly line participated as subjects in this study. Observations were made and recorded with respect to working postures practiced while performing their assembly tasks. Subjects' anthropometric data and current workstations dimensions were measured to determine whether they were suitable or not to perform the assembly tasks. Results: The findings from this study showed that there were four types of awkward postures and anthropometric data mismatches that had contributed to Musculoskeletal Disorders (MSDs) problems, faced by the subjects. Conclusion: The findings from this study shows current assembly workstation at Company A need to be redesign to eliminate awkward postures and anthropometric mismatches to lower MSDs problem and improve productivity among assembly workers.
Highlights
Clearance and angle of vision; and eye height are very important (Kroemer, 2008). Deros et al (2009) suggest
A literature review on past researches showed that there are few studies conducted with respect to new workstation design to solve Musculoskeletal Disorders (MSDs) and ergonomic problems faced by standing workers performing the various tasks
The assembly workers perform most of their assembly tasks while in the standing position
Summary
Clearance and angle of vision; and eye height are very important (Kroemer, 2008). Deros et al (2009) suggest. Zander et al (2004) had applied this concept for standing workers by conducting a study on different types of flooring conditions. Modification the workstation design is an alternative approach that can be used to overcome MSDs problems faced by standing workers. With respect to the physical design of an industrial workstation, four design dimensions that consist of: work height; normal and maximum reaches; lateral the workstation designer to incorporate the users’ anthropometrics data in specifying the appropriate dimensions for the workstation. A literature review on past researches showed that there are few studies conducted with respect to new workstation design to solve MSDs and ergonomic problems faced by standing workers performing the various tasks. CADWORK can be applied to design and build a new workplace from scratch or modify any existing workplace assembly layout fed into it. The two main objectives of conducting workplace assessment using CADWORK is to reduce the product assembly time and to design a safer workplace
