Kanban (Japanese: 看板 meaning signboard) is a scheduling system for lean manufacturing (also called just-in-time manufacturing, abbreviated JIT). [2] Taiichi Ohno, an industrial engineer at Toyota, developed kanban to improve manufacturing efficiency. [3] The system takes its name from the cards that track production within a factory.
A Kanban Board represents the system's Definition of Workflow [5] and requires the following minimum elements: A definition of the individual units of value that are moving through the workflow. These units of value are referred to as work items (or items). A definition for when work items are started and finished within the workflow. Your ...
Continuous-flow manufacturing, or repetitive-flow manufacturing, is an approach to discrete manufacturing that contrasts with batch production.It is associated with a just-in-time and kanban production approach, and calls for an ongoing examination and improvement efforts which ultimately requires integration of all elements of the production system.
The downstream station moves the kanban to the upstream station and starts producing the part at the downstream station; The upstream operator takes the most urgent kanban from his list (compare to queue discipline from queue theory) and produces it and attach its respective kanban; The two-card kanban procedure differs a bit:
A kanban board. A kanban board is one of the tools that can be used to implement kanban to manage work at a personal or organizational level.. Kanban boards visually depict work at various stages of a process using cards to represent work items and columns to represent each stage of the process.
Kanban systems combined with unique scheduling tools, dramatically reduces inventory levels, increases turns, enhances supplier/customer relationships and improves the accuracy of manufacturing schedules. Kanban aligns inventory levels with actual consumption; a signal is sent to produce and deliver a new shipment when material is consumed.
An example of a Heijunka box. The Heijunka box allows easy and visual control of a smoothed production schedule. A typical heijunka box has horizontal rows for each product. It has vertical columns for identical time intervals of production. In the illustration on the right, the time interval is thirty minutes.
CONWIP is a kind of single-stage kanban system and is also a hybrid push-pull system. While kanban systems maintain tighter control of system WIP through the individual cards at each workstation, CONWIP systems are easier to implement and adjust, since only one set of system cards is used to manage system WIP.
