1. Earth to Orbit Logistics and Supply Chain Modeling and Simulation for NASA Exploration Systems Mohammed Fayez, Dayana Cope, Assem Kaylani, Mike Callinan Productivity Apex, Inc.

2. Project Objective Develop a Space Exploration Supply Chain (SESC) modeling, simulation, and analysis

3. 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.

4. 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

5. 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 $

6. 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.

7. 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.
