 About the Computerized Baggage
         Handling System
• Designed by BAE Automated Systems Inc.
• The system consisted of a network of PCs
  communicating with thousands of remotely
  controlled carts
• The carts carried the baggage on a 21-
  mile underground track, also equipped
  with wireless communication equipment,
  linked to the PCs
 About the Computerized Baggage
     Handling System Cont.
• The PCs kept track of every bag’s current
• The carts carried the bags from check-in
  counters to sorting areas where their bar-
  code tags were scanned
• Baggage handling at the DIA was
  supposed to be fully automatic and highly
Problems with Baggage System
• The system could never process baggage
  of arriving flights
• The system failed and stopped functioning
• The software occasionally misidentified a
  bag’s destination, and the conveyor
  sometimes crushed bags
  Problems with Baggage System
• When the system failed, bags had to be
  handled manually, causing flights to be
• Also, many bags were not on the same
  planes as their owners
• United Airline’s mishandling ratio at DIA
  was higher with the system than at airports
  where baggage was handled manually
         Fixing the Problem
• At Denver the mishandling ratio was 12.4
  bags per 1,000, with the system constantly
  failing, in San Francisco the ratio was 6.1
  per 1,000 without the system
• The system was supposed to save labor
  and in return lowering cost
• Instead the system cost United Airlines a
     Fixing the Problem Cont.
• United Airlines decided to switch back to
  manually handling the baggage at the DIA
• This decision saved the airline $1 million a
• Had the system worked properly, it would
  have been deployed in may airlines
• Since it failed, no one besides United
  Airlines even tried it
Outcome of Removing the System
• United Airline’s executive said the main
  reason for switching back to manual
  handling was not to save cost but to
  improve customer service
• Getting rid of the system would save
  maintenance cost and also the cost of
  compensating customers for lost and
  misrouted bags
