Trevor AndrewsIndustrial & Systems Engineering Holli MonroeMechanical Engineering Emily Piccione Industrial & Systems Engineering William Wright Mechanical Engineering The project team would like to acknowledge and express appreciation to RIT faculty member Scott Bellinger for all of his help and assistance in executing this project.

In order to improve quality on the four-station assembly line within the Toyota Production Systems Lab at the Rochester Institute of Technology, two andon systems and a corresponding monitoring system were developed.  One andon system consists of simple electronics controlled by predetermined logic.  The other andon system is purely mechanical in nature. In order to highlight and record abnormalities, which can later be used to perform root cause analysis and develop preventative countermeasures, a monitoring system was designed alongside the andon systems.

Under $3,000 budget!

For more on Test Summary and Results consult EDGE webpage.EDGE webpage 82 states were tested and their expected behavior was monitored for accuracy Global:does the global display depict proper states Local: do the local displays depict proper states Light Tree:does the light tree illuminate according to button press Audio: does music play when an andon alert exists Red: does a yellow andon alert escalate to a red andon alert after X% of TAKT Reset: does pressing the andon button a second time reset the andon alert

For more on User or Operator Instructions/ Manual consult EDGE webpage.EDGE webpage A user or operator instructions/manual was crated to guide team members through the proper use of the various andon systems.

For more on Service Instructions/ Manual consult EDGE webpage.EDGE webpage A service instructions/manual was crated to guide team leaders and lab instructors through the proper set-up, modification, and maintenance of various andon systems.
