Just In Time In Toyota Production System

     Toyota was the largest listed company in Japan by market capitalization and by revenue. The company was founded by Kiichiro Toyoda in 1937 as a spinoff from his father company Toyota Industries to create automobiles.

     Many benefit about Just-in-Time (JIT) system to Toyota Production System. A production system which is steeped in the philosophy of "the complete elimination of all waste" imbuing all aspects of production in pursuit of the most efficient methods. Toyota Motor Corporation's vehicle production system is a way of "making things" that is sometimes referred to as a "lean manufacturing system" or a "Just-in-Time (JIT) system," and has come to be well known and studied worldwide.
     This production control system has been established based on many years of continuous improvements, with the objective of "making the vehicles ordered by customers in the quickest and most efficient way, in order to deliver the vehicles as quickly as possible." 
     Just-in-Time (JIT) system can make productivity improvement. Just-in-Time (JIT) system is making only "what is needed, when it is needed, and in the amount needed!" Producing quality products efficiently through the complete elimination of waste, inconsistencies, and unreasonable requirements on the production line.
     In order to deliver a vehicle ordered by a customer as quickly as possible, the vehicle is efficiently built within the shortest possible period of time by adhering to the following four factor. First is when a vehicle order is received, a production instruction must be issued to the beginning of the vehicle production line as soon as possible. Second is the assembly line must be stocked with required number of all needed parts so that any type of ordered vehicle can be assembled.

    Beside, third is the assembly line must replace the parts used by retrieving the same number of parts from the parts-producing process (the preceding process). The last one is number four about the preceding process must be stocked with small numbers of all types of parts and produce only the numbers of parts that were retrieved by an operator from the next process.
