What is JIT and Kanban System ?


JIT and Kanban System:

JIT and Kanaban System:Just-In-Time is a Japanese manufacturing management method developed in 1970s. It was first adopted by Toyota manufacturing plants by Taiichi Ohno. The main concern at that time was to meet consumer demands. Because of the success of JIT management, Taiichi Ohno was named the Father of JIT. The just in time manufacturing system considered as a pull system.The principle of Just in time (JIT) is to eliminate sources of manufacturing waste by getting right quantity of raw materials and producing the right quantity of products in the right place at the right time. The term “Kanban” has sometimes been used as equivalent to JIT, which certainly is not the truth. Kanban is a Japanese word for “card”. They often use cards to signal the need for more material, hence the name kanban. The idea behind the kanban system is to authorize material for production only if there is a need for them. Through the use of this system, production is “Pulled” through the production system; instead of “Pushed” out before if is needed and then stored.In general, kanban system works in the way that, two cards are used; a “withdrawal kanban” and a “production kanban”. These cards are very simple, showing only the part number and name, the work centers involved, storage location, and the container capacity. The approach is illustrated in figure (2).For example, assuming that work floes from work center number one WC1 to WC2, and containers are used to transport the output from WC1 to WC2, where they are used as inputs. When WC2 sees that it will need more input parts, it takes an empty container and a withdrawal kanban back to WC1. There it leaves the empty container and locates a full one, which has a production kanban with it. WC2 replaces the production kanban with its withdrawal kanban, which authorized it to remove the full container and the withdrawal kanban. It puts the production kanban in a rack at WC1, thereby authorizing the production of another container of parts. Back at WC2, the withdrawal kanban is placed back in its rack. WC1 cannot initiate production and fill an empty container until it has a production kanban authorizing additional production. Thus, withdrawal kanban authorize the acquisition of additional material from a supplying work center and production kanban authorize a work center to make additional product. Figure (3) illustrate the work of kanban system in manufacturing process:Although, the main advantage of kanban system is it's implicitly but, it is not appropriate in many manufacturing environments and cannot be applicable without preparing several requirements.
