10. Just-in-Time (JIT)(ch 8 in Chais).ppt

This is slide on just time time philosophy

1. Just-in-Time (JIT)
used to refer a production system in which both
the processing and movements of goods occur
just as they are needed, usually in small batches
JIT is a characteristic of lean production system,
which operates with very little “fat”
Benefits
•Lower processing cost
•Fewer defects
•Greater flexibility

2. Just-in-Time (JIT)
Objectives
•Eliminate disruption
•Make system flexible by reducing setup time
and lead time
•Eliminate waste, especially excess inventory
Building Blocks
•Product design
•Process design
•Personnel/organizational elements
•Manufacturing planning & control

3. Just-in-Time (JIT)
Product Design
•Standard Parts: workers have fewer parts to deal with,
training time and costs are reduced
•Modular design: clusters of parts treated as a single unit
•Highly capable production system: poor quality can
create major
disruption

4. Just-in-Time (JIT)
Process Design
•Small lot size
•Setup time reduction
•Manufacturing cells
•Limited WIP
•Quality improvement
•Production flexibility
•Little inventory storage

5. Just-in-Time (JIT)
Personnel/Organizational Elements
•Workers as asset
•Cross-trained workers
•Continuous improvement
•Cost accounting
•Leadership

6. Manufacturing Planning & Control
•Level loading
•Pull system
•Visual system
•Close vendor relationship
•Reduced transaction process
Just-in-Time (JIT)
•Preventive maintenance
