Since the early 1990s, Georgia Tech faculty have been exploring new methods for performance assessment of industrial systems, with particular emphasis on warehousing operations. The methodology being developed is related to data envelopment analysis (DEA).  DEA allows analysis of multiple system input and output measures, as opposed to traditional one-output/one-input productivity analysis methodologies.  The iDEAs website allows a warehouse manager to compare the efficiency of his or her warehouse against a theoretically "most efficient" warehouse, computed using data from a variety of different warehouses.  Each manager has access to the results, but only has access to his or her own data, not specific data from other warehouses.
