The Just-in-Time methodology is an industrial philosophy that can be summed up in manufacturing the products strictly necessary, at the right time and in the right quantities: you have to buy or produce only what is needed and when it is needed.
Definition
Just-in-time manufacturing means producing the minimum number of units in the fewest quantities possible and at the last possible moment, eliminating the need for inventory.
It is a philosophy that defines the way the production system should be managed. It is an industrial philosophy of eliminating anything that implies waste or waste in the production process from purchasing to distribution. Waste, in this context, means anything that does not add value to the product. It is a methodology to achieve excellence in a manufacturing company, based on the continuous elimination of waste such as inspections, transport between machines, storage or preparation. Precisely the name of this production method indicates its work philosophy. raw materials and products arrive just in time, either for manufacturing or for customer service.
The just-in-time (JIT) production system is a system for adapting production to demand that allows the diversification of products by increasing the number of models and their units. One of its main objectives is to reduce stocks, strictly maintaining the necessary ones (zero-base stock methods), which implies a change in the mentality of the production process, distribution and marketing of products, seeking to achieve synergistic advantages in the production-consumption chain.
Origin
The just-in-time concept began shortly after World War II as the Toyota Production System. Until the late 1970s the system was restricted to Toyota and its family of key suppliers. In the following years it spread throughout Japan and by the 1980s it reached the West, with the automotive industry as a catalyst.
Elements
The Just in Time philosophy has seven elements - six internal and one external - namely:
- Internal
- The Just-in-Time philosophy itself Quality at the source Uniform factory load Matching operations Minimum machine setup time Kanban
- Just-in-Time Shopping -external-
Three subsystems are included in the JIT system: the manufacturing JIT, the information processing JIT and the transportation JIT. In short, the integration into the logistics chains of the exchange of goods, of the subsystems corresponding to industry, commerce and transport is proposed.
Benefits
Correctly executed the Just-in-Time philosophy reduces or eliminates much of the waste in purchasing, manufacturing, distribution and manufacturing support activities (office activities) in a manufacturing business. This is accomplished using the three basic components: flow, quality, and employee engagement.
