Kanban for Shared Resource
By Jean Cunningham:
Normally when I think of Kanban, I think of external Kanban between the manufacturing cell and the external supplier. However, kanban within the plant when there are shared resources is very common too. (At least until all equipment/resources are able to be dedicated to product lines.)
For shared resources using Kanban we had to figure out a way to prioritize different kanban signals coming to the shared resource. The method I am most familar with is to segment the time available for the shared resource into time slots that each product line could utilize. This worked really well with a paint line, or pallet building area.
I would like to hear from some of our readers on visual methods used to schedule a machine shop which is shared by multiple assembly product lines. While we would like to have dedicated equipment, the shop isn't big enough yet; therefore we have to find a good way to help the machine shop to prioritize the various signals coming to them.
