The Kanban fixed batch system facilitates the monitoring and the launching of production which makes the workshop autonomous. The Kanban system has 2 operational loops :
• The supply loop which brings goods to the production line.
To avoid disrupting the Kanban system by the loss of a card, each card is placed in a specific position for each step of the process.
• The production loop which organises the production line process.
• The supply card goes from the container into the gutter on the desk onto the card holder of the container.
• The production card goes from the container in the batch box into the slot of the container's card holder.
