P13716: Andon System for Toyota Production Systems Lab
Project Objective: The objective of this project was to introduce Jidoka to the four-station assembly line within the Toyota Production Systems Lab at the Rochester Institute of Technology. Background Information: Jidoka is a term used in the Toyota Production System that refers to diagnosing an abnormality immediately and correcting it accordingly so that defects are not passed along to the next operator. An Andon system is a principal components of Jidoka.
Mechanical Andon Systems:
Electrical Andon System with Monitoring:
Design Specifications:
Visible from 30 feet
Inexpensive
Simplistic design for ease of use
System should accommodate additional stations
Design Specifications
Includes paced line capability
Global display tracks station status
3 activation modes, green, yellow and red
Each station accommodates NTID needs
Andon System Particulars:
Team Member input (button press) triggers an automated response from PLC programming
PLC program operates station lights according to station status
LabVIEW interfaces with PLC to display real-time data regarding the statuses of stations
Data mining capabilities created to promote future root cause analysis and preventative countermeasure development
Andon System Particulars:
Team Member initiates visual cue (colored cone or colored magnet)
Team Member initiates auditory cue (voice alert or bell)
The combination of cues prompts Team Leader to visit given station
