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.
