2. Description of the Concept
• The world owes a great deal to Mr Taiichi Ohno.
He has shown us how to manufacture more
efficiently, reduce costs, produce greater
quality, and also take an important look at how we
as people work in a factory. (Ohno, Taiichi, 1978)
3. Description of the Concept
The Toyota Production System was conceived with the principal objective
of producing many models in small quantities. This way, Toyota would
fulfill its main goal of costs reduction.
Toyota Production System = elimination of waste.
TPS Main Pillars
JIT = Just-In-Time
Autonomation
4. Just-In-Time: An Ideal State
In a a flow process, the right parts needed in assembly
reach the assembly line at the time they are needed and
only in the amount needed. A company establishing this
flow throughout can approach zero inventory, which at
the same time, reduces waste and costs.
5. Just-In-Time: An Ideal State
Traditional
Approach
Supply materials from an earlier
process to a later process
Toyota Reverse
Approach
Providing that every link in the
just-in-time chain is connected
and synchronized, a later
process goes to an earlier
process to pick up only the right
part in the quantity needed at
the exact time needed.
6. Autonomation; The Human Touch
Autonomation
• Autonomation refers to the situation in which machines can prevent
technical problems “autonomously
Human Touch
• The worker can stop the machine whenever there is a defective
production. As a result, one worker can attend several
machines, making it possible to reduce the number of operators and
increase production efficiency.
Multi-Skills
• Thus; An operator must develop skills for operating several machines in
order to reach optimal efficiency.
7. TPS Was Born In Japan Out Of
Necessity
Two Economic
Originators of
the TPS:
Oil crisis of
1972.
Conseqent
Slow Growth
