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).
