  1. Assessing the Relationship between Operational Performance and Affordability throughout the Life Cycle 21-24 July, 2015 Tom Collipi Technical Fellow Northrop Grumman Aerospace Systems Approved for public release; NG15-1031, 5/26/15

  2. Abstract Today’s financial and political environment is one of shrinking defense budgets in the face of constant or increasing threats. As such, there is a need to increase the efficiency and productivity of defense spending. In response to this, the US Department of Defense has established affordability targets, such as: average unit acquisition cost and average annual operating and support (O&S) cost. These key performance parameters are tracked and reported at each of the procurement milestone decision points and throughout the weapon system’s life cycle. Until recently, comprehensive modeling and simulation tools have not been available to support required trade studies or analyses that forecast the relationship between operational performance (i.e., Availability, Launch Schedule Effectiveness, Effective Time on Station, etc.), support resources (i.e., spares, support equipment, facilities, and manpower) requirements, and overall O&S costs. Using an object oriented simulation engine, material availability can be modeled using the planned operational utilization, the inherent R&M characteristics, the scheduled maintenance requirements and the necessary support resources. This technique establishes a closed loop system – where a specific set of support resources result in operational capability (material availability, mission capable rate, break rate, fix rate, departure reliability, etc.). The cost of these resources can then be estimated to form the foundation of the overall O&S cost. This presentation offers a methodology to model this complex performance-versus-affordability interaction: • Early in the concept definition process to develop the initial O&S cost estimates and resulting performance • During the development process to refine these estimates, and • Throughout the rest of the weapon system’s life cycle (initial fielding, operations and sustainment and disposal). This presentation will examine the implications of manpower policies on the ability to generate effective time on station and the cost of providing that surveillance coverage.
