Global Response Force Outload Decision Support Tool

1. Global Response Force Outload Decision Support Tool Zachary Horowitz, Tyler Maeker, Marissa Malta, and Thomas Schafer Advisor: Major David Beskow UNCLASSIFIED

2. Problem Definition Develop an Out-load Decision Support Tool (ODST) that builds/adjusts the Vehicle List (PVL) and optimizes vehicle to various types of aircraft. Priority assignment

3. Agenda • Introduction • Prioritization • Assignment • Range • Visualization • Implementation • Questions UNCLASSIFIED

4. Introduction GRF A lot has to happen here N-hour N-hour +18 UNCLASSIFIED

5. Introduction to Our Problem N-hour +3 N-hour +18 UNCLASSIFIED

6. Functional Hierarchy

7. Prioritization Prioritization • Multi–Objective Decision Analysis (MODA): Creating a value model that takes multiple criterion into account and weighs their importance based on stakeholder’s needs to give each vehicle a value which can in turn be used to rank them. • We explored using War Fighting Functions, Echelon, and Company Level Units as criteria for a value function Which of these is more Important for a given mission? Did Not Adequately approximate commander’s prioritization UNCLASSIFIED

8. Prioritization as Implemented • The ODST allows prioritization by capability rather than vehicle • This allows for the commander to have greater flexibility when various missions arise UNCLASSIFIED

9. How do we optimally assign vehicles to Aircraft??? Linear Programming Heuristic Algorithm or UNCLASSIFIED

10. Linear Programming Formulation: Minimize Empty Space Minimize Deviations from Priority List Implemented in Excel using OpenSolverhttp://opensolver.org/ UNCLASSIFIED

11. Heuristic Algorithm • Heuristic Algorithm is an intuitive approach created to logically and simply solve a complex problem. • Begin by assigning prioritized vehicles to aircraft. If a vehicle doesn’t fit, check each previous aircraft available space before moving to a new one. UNCLASSIFIED

12. Comparison of Assignment Methods • Comparison showing performance example when assigning 26 aircraft. • Empty space measure shows that both methods perform at the same level. • The heuristic does much better in comparison to the linear programming method as the alterations from the commander’s PVL are significantly less. Deviation of 2 1 2 3 4 UNCLASSIFIED

13. ODST Outputs • This graphic provides a visualization of combat build by warfighting function. • The independent variable is flight numbers, and the dependent variable is cumulative vehicles by warfighting function. • This graphic allows commanders to visualize the total number of vehicles by category available at various times during the mission, stimulating re-prioritization if the mix of vehicles is not appropriate for a given time frame. UNCLASSIFIED

14. Range Calculations Lockheed C-130 Hercules • We collected data from the Institute for Defense Analyses for aircraft range as a function of payload for C17 and C130 aircraft • Used a polynomial fitting function to represent the relationship for both • Implemented this in the tool to using the assigned payloads to calculate range of mission aircraft Payload (short tons) Range (Nautical miles) UNCLASSIFIED

15. Demo UNCLASSIFIED

16. Implementation and Way Ahead The 2nd Brigade Combat Team will test and evaluate the ODST as they prepare to take over responsibilities of the GRF. The 2nd BCT is the first brigade of the 82nd Airborne Division to transition to the new “Brigade Combat Team 2020.” UNCLASSIFIED

17. Problem: Prioritization and Assignment currently take weeks to manually produce and are inflexible when complete Solution: With ODST this prioritization is accomplished in hours and is flexible enough to adapt to multiple mission profiles UNCLASSIFIED
