• Kanban ( Kan=card, Ban=signal) developed at Toyota 1950s to manage material flow ; • Kanban is an information network used to control production quantities; a communication process that controls the movement of material; a tool to implement JIT. Simple movement system “cards” to signal & communicate reorder information boxes/containers to take “lots” of parts from one work station to another (client-server). Kanban Introduction
Rules of kanban 1.Parts are never to be produced or conveyed without a Kanban; 2.Kanban comes from downstream process; 3.The upstream process produces items in the quantity and the sequence indicated by the Kanban: 4.The downstream process draws only what is required by the Kanban from upstream processes; 5.Kanban must be attached to the actual containers of parts; 6.Never send defective products to downstream processes. 上浒充通大粤
