Cell Production System
UMC carries out the KAIZEN activity named UPS (UMC Production System) under the tutelage of PEC(Production Education Center) as the driving force of Toyota Production System.
UMC pursues the most rational production method, process and operation to suit customer products from the view point of "Waste finding eye" by PEC Morale Training.
UMC challenges to shorten Lead Time by aggressive efforts acting from Point Improvement(Individual) to Line Improvement(Team).
Cell Lines and One Person Workbench System based on the workability analysisis effective for Cost Reduction and Productivity Improvement.
