IEとQEのコラボレーションによる製造工程合理化手法の提案

抄録

So far, industrial engineering (IE) and quality engineering (QE) have been used as independent improvement methodologies. Some manufacturing processes can be rationalized by use of either industrial engineering alone or quality engineering (inspection design) alone, but in other cases this is difficult. Especially in a production line including inspection processes, the major issue is how to optimize the entire line, including deciding which items should be inspected. This study focuses on the scale by which improvement is evaluated,and demonstrates that manufacturing processes can be rationalized by making use of the synergy effect of industrial engineering, which evaluates time, and quality engineering, which evaluates loss. The method introduced here can become a general-purpose rationalization methods (model) that links industrial engineering and quality engineering, and has the potential to be widely applied to rationalization of production lines including inspection processes. Further research and wider utilization of this method at many production sites are expected to lead to productivity improvement in manufacturing industries.
