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
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.

Step 3: Logistics Agent takes appropriate actions (e.g.

providing email notifications, performing computations,

etc.)


Work to be performed in year 3
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).
