Summary By Kandyce Bohannon

Project Objective

Develop a Space Exploration Supply Chain (SESC) modeling, simulation, and analysis

Space Exploration Supply Chain

Crew members and supplies are sent into locations in space.Valuable data, newly acquired knowledge, and physical samples are sent back to Earth.

WHY?• In 2005 the Exploration Systems Architecture

Study was founded in order to build a permanent base on the moon by 2020 and eventually establish similar strongholds on Mars.

• Necessary supplies include fuel, food, spare parts, exploration equipment, and oxygen

Reasons to Simulate

• Vastness of the system• Uncharted locations mean

unpredictable conditions• Amount of time it would take to run

an experiment of this type• $ Expense $

Simulation

• Begins with a basic session file which represents the “as is” simulation model of the supply chain system

• User can create “what if” scenarios– After general data has been collected, the

user is prompted to make adjustments if applicable through use of the Graphical User Interface.

– These adjustments include intermediate and final deliveries, available resources, and interactions among people involved.

Analysis Capability

• The simulation report is saved in an XML session file where the base model and the “what if” model(s) simulations can be compared side-by-side.

• Report includes texts, tables, and graphics.
