Abstract
In the early stage of the Weapons Acquisition Process (Concept Exploration and
Concept Demonstration/Validation Phases) no exact and reliable data are available
about expected Mean Times Between Failures (MTBF) and Mean Times to Repair
(MTTR) for both the components of a new system or the new system itself. Nevertheless,
appropriate decisions have to be made about the number of maintenance facilities
at certain military command levels, about the needed quantity of (military and/or civilian)
maintenance personnel, and about adequate spare stock levels at the appropriate
locations.
Wrong planning in this early stage can cause a degradation of the new system's future
availability. This is problematic especially with electronic equipment, because
maintenance personnel have to be highly specialized, and can not be replaced and retrained
as easily as support personnel for trucks or tanks.
A decision aid for the early stages of the acquisition process is needed that offers
insight into the behavior of a multi-indenture level electronic system within a three echelon
maintenance system, develops alternatives for upcoming decisions, and finally provides
information about sensitive factors and their possible tradeoffs, essentially used in
budgetary discussions.
The purpose of this thesis is the exact definition of all relevant factors pertaining to
the necessary decisions, the review of existing models and tools and their review for applicability.
Because the modification of existing programs can not solve the whole scope
of the problem due to the use of early generation computer languages, and due to the
necessarily new and different approach to the topic, a new simulation program has to
be developed. Using object oriented simulation language MODSIM-II, first steps towards
this program are made, but remain to be improved and completed in further research
work.
