Kanban

kanban

Kanban the no-inventory method of operation was first developed by the Japanese company Toyota motors and quickly implemented in manufacturing companies worldwide. It is mostly used in mechanical engineering.
The method is based on the following principles:

  • the supplier is responsible for quality and customer is always obliged to accept the delivery ordered
  • capacities of the supplier and the customer are in balance and their activities are synchronized
  • material consumption is uniform without large fluctuations and changes in assortment
  • both the supplier and the customer do not create any stock
  • there are so called self-regulatory circuits consisting of pairs of cells (supply and consumption) which are linked on the basis of the so called pull principle

The order quantity is given by the capacity of one or more transport vehicles, always fully loaded with a constant amount of material – the material and information flows take place in the following steps – procedure:

  • the customer sends the empty transport vehicle to the supplier with the label (Kanban in Japanese) – the dispatch note which fulfils the role of the purchase order
  • upon receipt the supplier initiates production of the particular batch
  • when the transport vehicle is filled with the material, it is sent back to the customer (identified with the label – dispatch note)
  • the customer checks and accepts the delivery

Short circulation of goods

  • quick response to demand
  • additional quality control is not required
  • optional pre-assembly
  • fault reduction

Reduced costs of transport

  • high efficiency
  • no individual inquiries and purchase orders
  • no warehousing costs
  • no tracking of deadline orders is required
