Army Logistics Integration Agency(LIA)

• LIA has a Virtual Operations Center concept
  which will
• allow analysts integrated access to a variety of
  data sources (AWR, AA)
• allow analysts to pipe results of data access
  to planning, analysis and visualization tools.
• allow analysts to register mission-critical
  conditions they need to track and couple actions
  to the evaluation of such conditions.

Army War Reserves Data Sets

• 4 AWR data sets used so far
• LOGTAADS data sets - 2 files containing
  multi-table, multi-record structures.
• ORACLE data - 2 data sets.
• Distributed machines, running two OSs - Unix and
  NT.
• Logisticians can specify conditions they want to
  monitor.
• Logisticians can specify actions (e.g. send-mail,
  post web page, etc.) to be taken when these
  conditions are triggered.

Example

• John Smith wants to track the quantity of supply
  items in the P category on the ship
  Alexandria.
• When the quantity drops below an 95 fill (I.e.
  the Alexandria has less than 95 of the P items
  it should have), he wants an email sent to him
• Two steps
• John Smith interacts with IMPACT Logistics Agent
  Interface (see right).
• IMPACT Logistics Agent tracks changes to data for
  all conditions and triggers actions.

Work to be Performed in year 3

• Develop incremental algorithm to evaluate effect
  of data changes on conditions of interest.
• Develop algorithm to merge multiple interests
  together so as to reduce system load.
• Extend the range of AWR data sets.
• Extend the range of analytic, planning and
  decision tools used in AWR Logistics Agent.
• Extend the range of actions taken by AWR agent to
  handle database updates (already supported in
  IMPACT, but not in this application).
