Relationship between complexity in manual assembly work, ergonomics and assembly quality

Paper i proceeding, 2012

Earlier studies have demonstrated strong relationships between manual assembly at high physical load levels and increased amounts of quality errors compared to assembly at low physical load levels. A recent Swedish interview study indicated that assembly complexity is also of importance for the assembly quality. The objective of this study was to examine the significance of complexity and the relationships between ergonomics, assembly complexity and quality by analyzing manual assembly tasks in car manufacturing. The results showed several significant correlations between ergonomics and assembly complexity, assembly time, failures and costs.
