Manual work analysis and simulation system framework for performance improvement in manned assembly line

Presented in this paper is a framework for analysis and simulation for performance improvement of manual work in a manned assembly line. In a manufacturing system, productivity is a key of competitiveness for output products, and the manual work performance is one of the decisive factors of productivity of a manned assembly line. However, existing approaches to the manufacturing systems are limited to matters of the plant layout or the robot tasks design in the automated factory and to the manual work are concentrated on the ergonomic based workload analysis. Consequently, the modern approach for the manual work performance improvement has not been researched. As a solution of the current problem, this study proposes a system that analyzes manual work based on work design approach using video-recording, and the system executes a brief simulation of newly derived work standard from the analysis.
