Park  \nAbstract—Presented in this paper is a framework for analysis and simulation application 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 ofthe 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 an application 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.  \nIndex Terms—Assembly line, manual work, simulation, work video analysis.  \nI. INTRODUCTION  \nProductivity of a manufacturing system is one of the important elements that decide the enterprise competitive power, such as market flexibility and quality management. Manufacturing enterprises must carry out an activity for productivity improvement continuously. The manned assembly line is a process of manufacturing systems, which is suitable to massive manufacture having better flexibility than the automated system. This process has been adopted in the industry for electronic appliances, i.e. television and refrigerator. Because the industry has many different product types and frequent changes, to design the manufacturing system as fully automated using dedicated tools is hindered by the view of cost-effectiveness. The process is structured by three factors of machine, worker and material (see Fig. 1), and the productivity is determined by machine capacity, worker performance and product design. After built up all the equipment and operation plans of assembly lines, it is difficult to modify the layout or replace the equipment. Therefore, improvement of the worker performance is an appropriate approach to the productivity enhancement of installed lines. Although jobs on an assembly line normally does not require high-skilled workers because of an aggregation of repetitive tasks, such as picking a component from toolset and assembling a component with a base laid on a conveyor, a slow workstation by a low-skilled worker  \nManuscript received May 10, 2013; revised July 10, 2013.  \nThe authors are with the Dept. of Industrial Engineering, Ajou University, Korea (e-mail: [lunacy@ajou.ac.kr](lunacy@ajou.ac.kr), [webmacom@ajou.ac.kr](webmacom@ajou.ac.kr), [scpark@ajou.ac.kr](scpark@ajou.ac.kr), [yongho1230@gmail.com](yongho1230@gmail.com)).  \ncauses delay of former workstations and idle of latter workstations. In other words, poor performance of one workstation affects to the entire assembly line flow, and it causes, as a result, a decline of productivity of the line.  \nFig. 1.

This research is to select process type (i.e. job shop, batch, assembly, continuous) based on the diversity, flexibility and yield of output products of the system and to apply the selected process to the target manufacturing system.
