Pull system

Definition

is a production management system that reaches the control resource flow by only supplemented resources. The time required to produce, according to the needs of the products, according to the number of products, and the products needed.

Generating the background

The car market in Japan in the middle of the 20th century is very small, unstable, but more needs for product types

car company status Yes:

· Product quality is unstable

· Delivery length

· Total models variety, small volume small

· production The inventory in the process is great

Toyota company found:

· The number of items per item is usually standard

· Customers buy the required items, shopping malls to supplement

· Supplier According to the consumption of items, the new goods are shipped to the shopping mall

· The items in the supermarket are easy to expire.

Toyota company has invented the pulled production method (or the time-based production method JIT, or the production method). The time required to produce, according to the needs of the products, according to the number of products, and the products needed.

Target of the system

· Eliminate the following ware: handling, warehousing, outdated product, repair, rework, equipment, facilities, excess stock ( Including product and finished products in processing

· Reducing manufacturing costs and management costs

• Renewing the entire manufacturing cycle from putting into product delivery

Manage all resources

· Provide management and balanced logistics method

supermarket pull

in the inventory supermarket, there is a stock supermarket - To store the products it make it. Each process only needs to make up the product from its inventory supermarket. A typical example is that when the material is taken away from the inventory supermarket by the downstream process, a piece of board will be sent to the upstream, authorized to the upstream process, producing a product extracted.

Because each process is responsible for supplementing your own stock supermarket, the management of the work on the day of work is relatively simple, and the opportunity to improve will be more obvious. There is a shortcomings between the inventory supermarkets in each process, that is, each process must bear the inventory of the various products it manufactured. Therefore, when the product type is more, it is quite difficult.

Supermarket pull system

order pull system is also the typically said B-type pulling system, and the product is only "manufactured according to orders", and the inventory of the system is reduced to the smallest. This approach is most suitable for too much parts type, so that an inventory supermarket cannot accommodate various parts of inventory of various parts.

Supermarket pull system and sequential pull system can be mixed. Such a hybrid system is usually suitable for a company, with a small number of models, about 20%, accounting for 80% of the total production of the company. Depending on the output of various types, (a) high, (b), (c) low, and (d) four types of orders that are not frequent. The D-type representative is a special order or repair parts. To produce such low-yield products, you must create a special D-type board that represents a certain amount. In this case, the scheduling department can arrange the production order of the D-type product in order to pull the system in order.

This hybrid system has selected inventory supermarkets and sequential pulling, so that even if it is more complicated and variable, the company can make these two systems together, for the hybrid system, Balance tasks and discovery abnormalities often compare difficulties, management and improvement activities will be more difficult. Therefore, strong management is required to ensure efficient operation of the hybrid system.
