Nowadays, automobile manufacturers are faced with increasing global competition which is required low cost as well as high quality. To reduce shipping and handling cost and delivery time, lots of automobile manufactures tried to build their new factory in the neighborhood of market. Simultaneously, many factories are under construction in developing countries to make efficient use of low-wage workers. However, because systems are installed in developing countries as the same type of domestic facilities, systems have lots of problems such as high installation cost and inefficient use of manpower. To find core problems and generate optimal solution of these problems, thinking process of TOC(Theory Of Constrains) is used. In case of transmission gear machining system, semi-auto system is proposed as the best solution to increase manpower efficiency and system utilization. Semi-auto system consists of automatic machining process and manual transporting process. The system layout is generated based on semi-auto process concept. And, 3D simulation method using QUEST is used to verify production volume of generated system.

Nowaday, the increasing global competition put much pressure on increasing the efficiency and quality at all stage in the life cycle of manufacturing systems e.g., (re)design, implementation and operation. To increase efficiency, there is need to minimize the time and cost for development and operation of a manufacturing systems. Therefore, it becomes more and more to important to analysis and test a manufacturing system before a large investment.<br/> In this paper, we introduce procedure for digital manufacturing and OLP for high efficiency. And. according to these procedures, we implement a virtual laser welding cell using IGRIP and CATIA V5 as an example.
