JIT concept has the following goals: List 3

Benefits of JIT

The benefits of JIT include....

• Low inventory carrying costs

• Fast detection of defects in the production or the delivery of supplies and, hence, low scrap loss

• Reduced inspection and reworking of parts

• All of above

Requisites for JIT

• A pull system of production control

• A push system of production control

• Setup time reduction for smaller batch sizes

• Setup time reduction for smaller batch sizes

Pull System of Production Control

• A pull system in which the order to make and deliver parts at each workstation in the production sequence comes from the downstream station that uses those parts

• In this system, information flows in the opposite direction as production

• Pull manufacturing is a visual replenishment of goods, produced when demanded by the next work center

• answers 1, 2, 3

Pull / Push System of Production Control

• Push manufacturing is characterized by manufacturing to forecast, emphasizes on batch processing and lot sizes

• A push system in which parts are produced at each station irrespective of the immediate need for those parts at the downstream station

• The information flows in the same direction as production

• ALL the answers above

What is the difference between pull and push system in production?

• Used in MRP system

• Information flow is the main difference

• The information flows in the same direction as production

• The information flows in the opposite direction as production

Kanban means ........... in Japanese

Two types of kanbans are

• Production kanban – authorizes upstream station to produce a batch of parts. It specifies the kind & quantity of product which the preceding process must produce

• Inventory Kanban- use to keep inventory in warehouse systematically

• Transport (withdrawal) kanban – authorizes transport of the parts to the downstream station. Specifies the kind and quantity of product which the subsequent process should withdraw from the preceding process
