ANDON

Andon is derived from a Japanese term for a type of paper lantern. In manufacturing it refers to a system to notify management, maintenance, and other workers of a quality or process problem.

  • Green: Normal operations.
  • Yellow: – changeover or planned maintenance.

  • there is event schedule for understanding the maintenance activities,
  • graphical support for operators that are not in the plant,
  • emergency communication systems that enable electronic notifications.
