Recently, many manufacturers are recalling due to product quality problems. since it is difficult to record and utilize the manufacturing information in all steps of manufacturing, it is hard to figure out a cause of the quality problem clearly in the process of manufacturing and supplying parts. It is necessary to share the manufacturing information throughout the supply chain particularly among small and medium-sized manufacturers, but related infrastructure and information systems are in shortage. In this research, a 3D-based visualization system to cope with quality problems after product shipment was proposed. The proposed system shows the past state of the process and the flow of the logistics of the product in which the complaint after a shipment has occurred to the 3D-based visualization. It also shows the manufacturing history including product defect information and the status of each facility. In addition, it is possible to compare the production results for each scenario based on the built-in simulation function and perform alternative analysis on an improvement of the line such as buffer optimum capacity calculation or cycle time reduction. It was developed using open source for the diffusion of medium and small-sized manufacturing companies and applied to the actual production line of auto parts company.

Mass production was the main stream in manufacture industry for decades, however, small quantity batch production is becoming important as IT technology and data management system developed. In this industrial situation, manufactures are under pressure of shortening new product development time to meet custormer needs. DFMA provides guidance to the designer for simplifying the product structure to reduce manufacturing and assembly costs. Most of existing DFMA tools are implementing checklist method based on surveys on user experiences and assessing design under guidelines. This research suggests design-support system which is associated with 3D CAD systems to analyze assemblability and manufacture cost easily. Design-support system helps designer’s decision making using 3D CAD models and data to show product assembly structure and BOM.
