What is JIT?

JIT (just-in-time production mode) is also called non-inventory production mode, zero-inventory, single-flow or supermarket production mode.

Just-in-time system is a production mode implemented by Toyota Motor Corporation of Japan in 1960s. After 1973, this model played a prominent role in Toyota's first energy crisis, and then attracted the attention of manufacturers in other countries, and was gradually implemented in Japanese-funded enterprises and European and American local enterprises. This model, together with other production and circulation models from Japan, is called "Japanese model" by western enterprises.

Just-in-time system's understanding of inventory is completely different from traditional inventory control methods, which think that inventory is useless and a waste of resources. Traditionally, inventory can buffer operations, so inventory managers always consider how to provide buffering on the basis of minimum cost; Managers who believe in just-in-time operation are thinking about how we can eliminate our dependence on inventory.

It changes the previous procedure in the traditional production process into the latter procedure, and changes the latter procedure into taking goods from the former procedure according to Kanban. Kanban system is the core of JIT production site control technology, but JIT is not just kanban management. One of the foundations of JIT is balanced production, that is, the average production of products, which makes the logistics flow in a balanced and balanced way among operations, production lines, processes and factories. In order to achieve balance, JIT adopts monthly plan and daily plan, and adjusts the plan in time according to the change of demand.

The basic idea of JIT operation is that the supplier transports the materials to the designated place according to the requirements of the buyer (or kanban) and the requirements of the buyer's variety, specification, quality, quantity, time and place. Not earlier, not later, not more, not less, and ensure that the delivered materials have no defective products.
