Defense acquisition system simulation studies

Abstract

A systems engineering process model for the acquisition of large, complex systems for the U.S. Department of Defense (DoD) is being adapted for ongoing experiments in acquisition process policies. The discrete-event simulation model of the larger "enterprise of acquisition" for weapon systems has a broad scope from program beginning through development. It reveals some of the challenges and risks in weapon system acquisition. Initially the model was used to evaluate potential policies as interventions and/or system changes in an Air Force context. The simulation results showed varying degrees of influence on program outcomes and suggested no single antidote exists for solving acquisition problems. Many of the negative outcomes reflected through cost and schedule overruns are due to the behavior of the acquisition system itself. A collaboration between the Air Force Institute of Technology (AFIT), the Naval Postgraduate School (NPS), and The Aerospace Corporation is underway to translate the model and adapt it for new considerations. Shortly we will propagate new model versions and results to the public, and use it for additional Air Force and Navy programs of concern.
