Description of the Concept• The world owes a great deal to Mr Taiichi Ohno.He has shown us how to manufacture moreefficiently, reduce costs, produce greaterquality, and also take an important look at how weas people work in a factory. (Ohno, Taiichi, 1978)
Description of the ConceptThe Toyota Production System was conceived with the principal objectiveof producing many models in small quantities. This way, Toyota wouldfulfill its main goal of costs reduction.Toyota Production System = elimination of waste.TPS Main PillarsJIT = Just-In-TimeAutonomation
Just-In-Time: An Ideal StateIn a a flow process, the right parts needed in assemblyreach the assembly line at the time they are needed andonly in the amount needed. A company establishing thisflow throughout can approach zero inventory, which atthe same time, reduces waste and costs.
Just-In-Time: An Ideal StateTraditionalApproachSupply materials from an earlierprocess to a later processToyota ReverseApproachProviding that every link in thejust-in-time chain is connectedand synchronized, a laterprocess goes to an earlierprocess to pick up only the rightpart in the quantity needed atthe exact time needed.
Autonomation; The Human TouchAutonomation• Autonomation refers to the situation in which machines can preventtechnical problems “autonomouslyHuman Touch• The worker can stop the machine whenever there is a defectiveproduction. As a result, one worker can attend severalmachines, making it possible to reduce the number of operators andincrease production efficiency.Multi-Skills• Thus; An operator must develop skills for operating several machines inorder to reach optimal efficiency.
