2. 2 1999 IMPACT Workshop Credits Joint effort with: US Army Logistics Integration Agency (POCs: Bobby White, Jeffrey Shields, Miranda Moore) US Military Academy, West Point (POCs: LTC. Jack Marin, LTC. Ron Byrnes, and MAJ. Joseph Schafer) University of Maryland (POCs: T.J. Rogers, V.S.Subrahmanian)

3. 3 1999 IMPACT Workshop 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. Conditions to Track Data/software sources analysts updates

4. 4 1999 IMPACT Workshop 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. Java Client LOGTADDS Files NT 4.0 Server Web and Remote HERMES Servers Network Equip RU and APS- LOC Files Solaris 2.5 Workstation Solaris 2,5 Workstation

5. 5 1999 IMPACT Workshop 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. Logistics Agent Interface Condition Action Base IMPACT Logistics Agent Data agents

10. 1010 1999 IMPACT Workshop Step 1: Data agent ships update info to Logistics Agent. Network LogisticsAgent Data agent Logistics Agent, I

11. 1 1999 IMPACT Workshop Logistics Agent, II Step 2:Logistics agent evaluates conditions of interest to different users. Network Mediator

12. 1212 1999 IMPACT Workshop Logistics Agent, III Step 3: Logistics Agent takes appropriate actions (e.g. providing email notifications, performing computations, etc.) Network Mediator

13. 1313 1999 IMPACT Workshop 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).
