Abstract

Inspired by a recent model-based source selection conducted by the Advanced Range Threat System (ARTS) Program Office at Hill AFB, this research effort explored the development of new tools the DoD could use when evaluating models submitted with proposals. Specifically, the effort aimed to incorporate the Multi-Objective Decisions Analysis (MODA) framework into SysML diagrams as a solution for technical evaluations on models submitted with offeror proposals, eventually producing the Model-Based Decision Tool (MBDT). The MBDT is built from a Value Hierarchy based on key system requirements, each weighted by priority and measured by their own Single-Dimensional Value Functions (SDVFs). By integrating variables submitted with offeror proposals, the MBDT consistently and objectively evaluates the utility different designs offer the DoD. A toy problem was used to test the MBDT’s functionality in a mock source selection, demonstrating the tool’s potential to support future model-based source selections in the DoD. This initial release of the MBDT establishes a beachhead in digital evaluation methods for future contracts. By equipping the DoD with a method to perform model-based source selections the Department will be better able to evaluate proposals, assess technical risks against performance requirements, and conduct best-value tradeoffs with objective technical criteria.
