5.1 Summary of major or deeper changes that caused productivity improvement in coil manufacturing
The productivity improvement in coil manufacturing resulted mainly from the reduction of setup time of the expander through the application of LMS tools, which included VSM, SMED, and Kaizen (continuous improvement). Additional benefits were obtained through the reduction of WIP inventory and improved pant layout resulting in reduced shop floor congestion and coil damages and improved workplace safety.
The major changes of the shop that contributed to the improvements can be attributed to top management support for LMS philosophy, formation of LMS team, and provision of necessary orientation and training in LMS.
6 Conclusions
In summary, the conclusions reached from this investigation are the following:
1. LMS was successfully applied to improve productivity of airconditioning coil manufacturing.
