Kanban

A scheduling system indicating how many goods one must produce in a given period of time, how one must produce them, and by when they must be completed. It developed in Japan as a means to achieve just-in-time inventory control.

kanban

a Japanese term meaning ‘card’. It is used to describe part of the control mechanism for JUST-IN-TIME (JIT) and is at the centre of all JIT operations. A kanban is used to authorize the previous stage of production to make components. As such the system operates as a pull mechanism. A kanban system, to work successfully, should operate within the following conditions.
  1. A relatively stable demand pattern, with probably no more than 10% variation either side of the average.
  2. QUALITY is imperative, defects for components in the system must be at a minimum. This is because kanbans normally work at preset component levels.
  3. Good operator motivation. This is essential because a kanban is essentially a short-term, minute by minute inventory control mechanism. The simplest kanban is known as the kanban square. Here a square card (hence the name) is placed between two workstations. When the square is full (to a preset level) work at the previous station stops. When work is pulled from the square by the next operation (hence the alternative term ‘pull-system’) then work at the previous operation may start again. Kanbans exist in a number of variations, as stationary points attached to a work centre or as cards attached to an inventory bin, the principal remains the same however. See LEAN MANUFACTURING.

The authors describe the modeling assumptions, which are in fact, general assumptions applied when dealing with CONWIP and Kanban Systems, in order to make quicker/easier translations from the model to its interpretation, as for instance, each card (whether it is Kanban or CONWIP) represents one and only one part, thanks to which the number of cards in the line will help interpret immediately the number of parts in the system.
