Interplanetary Supply Chain Management and Logistics Architectures 2

Background

• Challenges for HMP Logistics– Organized last-minute– Ever-changing schedules

(weather, flights, funding)– Items left on base over the winter

are not tracked carefully

Interplanetary Supply Chain Management and Logistics Architectures 3

Inventory Goals

• Our Goals – Provide an inventory of items and

implement a tracking system for items during the field season and over the winter

– Catalog classes and sub-classes of supply in the field to obtain a complete inventory and relational database of a Mars-analog research base on Earth

Interplanetary Supply Chain Management and Logistics Architectures 4

Inventory Procedures

• Inventoried the following locations:

– Bathroom Tents– MIT Tent– Office Tent (inc.

Medical Supplies)– Research Tent– Core Tent– Mess Tent (inc.

food)– Greenhouse– Comm/Systems

Tent– Humvee– Outdoor Camp

Equipment • Tagged items with

RFID and barcodes

• Tabs for various inventory collections (e.g. food, mess tent, medical)

Excel Inventory Spreadsheet

Interplanetary Supply Chain Management and Logistics Architectures 6

Results• Outcomes

– >2300 items were cataloged in an excel spreadsheet– ~400 of these added to the relational database on-site for RFID tracking (MIT tent,

Mess tent)• Listed the following attributes for each item:

– Supply Class

– Name, Description

– Priority Level

– Hazard Type, Hazard Level

– Perishability Type, Perishability Units, Perishable Parameter

– Usage Rate Type, Usage Rate

– Origin Type, Owner, Storage Environment

– Packaging, Handling

– Mass Units Type, Mass, Size Units Type, Volume

– Cost/Value, Number of Items

– Location, Case ID, and Electronic Product Code (EPC)/Barcode.

Example Use Cases

• How many items in each supply class?• What percent of camp equipment is owned by each

participating organization?• What is the fuel availability on base, and where is it

located?

Mars Analog

• How analogous is HMP to Martian and Lunar bases, in terms of logistics?– Obvious differences include:

• HMP uses in-situ water resources• More frequent flights (resupply)• Relative ‘luxury’ in cooking/eating arrangements

– Compare estimates based on Draper/MIT CER surface demand models

Interplanetary Supply Chain Management and Logistics Architectures 12

Comparison to CER-based Estimates

• HMP waste collection system is simple, and depends largely on trash bags• HMP has several seasons’ worth of food stockpiled, and a wide variety of

kitchen equipment (accumulated over many seasons)

Summary

• Established a near-complete inventory of HMP base camp

• Validated the supply classes for Moon/Mars exploration• Provided usable baseline for planning upcoming 2006

field season– e.g. cook knows what food and supplies are on-base

• Populated relational database to enable RFID tracking– e.g. “how much printer paper is in the MIT tent?”

• Developed procedures for full-scale inventory and tracking of all supplies on an Arctic, Lunar or Martian base
