The Pratt and Whitney Addison Service Center is a unique situation involving rental engines and their repair.  These engines are delivered by a 3rd party carrier and must be checked over and repaired if necessary.  At that point the engine must be sent back out to either the customer who rented it or to another intermediate step.  The Addison, TX Service Center Manager requested help in optimizing the employee’s time spent on these rental engines.  He wanted to know what could be done to improve Service Center response time and maximize output.  One of the suggested scenarios that the manager wanted evaluated was if he was to put two or three workers on a project. Also, to what point should the workers take a non-AOG (non-priority) engine before storing it?  After careful review of what was being studied I came to the conclusion that the following questions needed answers as well:

  • What changes or policies can be made to optimize the use of employee time?
  • What changes or policies can be made to maximize output speed of AOG engines?

There are three virtually permanent LeaseCo employees that perform the work on these engines.  In addition there are some other people and departments that interact with this engine:

  • The Parts Department
  • The Internal Transportation
  • The External Transportation
  • The Storage Area
