Abstract
High Efficiency Particulate Air (HEPA) filter was introduced during the World War II for removing or blocking very small particles (0.3μm particles) or contaminant from entering the air stream into the clean space. A new HEPA filter production line has been developed, however it has no production management system for the new production line. A lean production management system for HEPA production was developed. Value stream mapping tool was applied by analyzing the current state situation and developed the future state improvement. Production flow was designed into five sessions as a batch flow process to improve the productivity in limited space of working environment and manpower. After reducing the wastes identified in current state study, future state development in production line showed 22% improvement compared to current state study.
