Distribution Based Logistics

• Working Definition
• DBL Is Management Of Inventory Flows, Rather Than
  Management of Inventory Levels.
• Underlying problem is management of Inventory in
  Motion
• This is emerging as an area of keen interest in
  the military and commercial logistics communities.

4
DBL-Analyzer Motivation

• Build a Simulated Environment In Which to Explore
  Distribution Based Logistics (DBL)
• Explore the Viability of DBL
• Explore the Challenges of Logistics Management in
  a DBL Environment
• Explore the Challenges Involved in Building (or
  Specifying) a DBL Management System

5
The DBL-Analyzer

• Project overview
• Rapid prototype in Gensym G2
• Designed as concept exploration tool
• Maps are GIF background images
• Most come from CIA public web site
• Key metrics are rates
• Flow rates measure inventory in motion
• Fill rates measure inventory currently on hand
• Units specify logistics requirements as
  consumption profiles, rather than through
  discreet requests.

DBL-A BASIC CYCLE(Class and Method View)

• DBL-SLS
• Single Log System
• CONDUCT-DBL
• SPLIT OUT COMMODITY-CONSUMPTION -PROFILES (CCP)
• SEND TO IMMCS

• DBL-IMMC
• Matl Mgrt Centers
• CONDUCT-DBL
• ROUTE CCPs TO SOURCES

• DBL-UNIT
• CONDUCT-DBL
• FILE CONSUMPTION -PROFILE (CP)
• CONSUME

• DBL-SOURCE
• CONDUCT-DBL
• HOLD CCPs
• FILL CCPS
• GET CONTAINERS
• STUFF CONTAINERS

• DBL-GL
• Global Locations
• CONDUCT-DBL
• IF FINAL DISTINATION
• PROCESS DP
• ELSE
• QUERY SLS TO PROVIDE DP NEXT HUB

• DBL-DP
• Distribution Platforms
• CONDUCT-DBL
• MOVE ALONG ROUTE TO NEXT POD Port of Debarkation

• CCPs start off on the subworkspace of CPs, then
  get transferred to the subwokspaces of
  DBL-Sources
• Different CCP classes would allow different
  commodity breakouts

Findings and Observations

• DBL Remains a Viable Alternative
• Much More Detail Needs to Be Added to the
  DBL-Analyzer
• DBL-A Is Relatively Easy to Integrate With Other
  G2 Logistics Models
• SIMULOGS, Rock Drill
• HLA Appears to Be Relatively Easy,
• However a Target Federation Should Be Defined
  First

10
Findings and ObservationsDBL Remains a Viable
Alternative

• Management of inventory in motion appears to be
  both doable and attractive.
• Especially applicable to the fast moving world of
  modern military operations and electronic
  commerce.
• An interactive interface appears to impart an
  urgency to operators throughout the supply chain

11
Findings and Observations More Detail Required

• DBL-A is currently too simplistic
• Many other functions need to be added
• freight consolidation , load throughput
  management, transportation network mgt.
• Need to first develop business rules.
• COTS transportation mgt. packages may help
• Interface with GTN and commercial systems needs
  to be worked out

12
Findings and Observations re HLA

• Experience gained in this project suggests, that
  seeking HLA compliance for a single model such as
  DBL-A may not be an effective use of resources.
• Building a federation within the DOD logistical
  modeling community and then as a community going
  through the Federation Development Process
  (FEDEP) would seem to be more efficient.

DBL-A Status

• Project Build 1 Completed for LIA in Aug 99
• LIA may reuse some components in related
  logistical modeling efforts
• Environment or components may be available for
  use in other DOD log models
