Whereas
the UK Land model provides a generic representation of the business
processes present within land systems, the US EFV model demonstrates
how commonality between OSCAM models can be used to develop
bespoke, program-specific tools.
Through the process of workshops comprising subject matter experts
and experienced cost analysts, the options for the support system
and operating policies of the EFV had been defined prior to
translation into a simulation model at the quantitative level.
A Data Management Tool (DMT) for the OSCAM EFV model has also
been developed, enabling maintenance philosophies to be applied
to component level data within a work breakdown structure prior
to simulation.
In addition, the OSCAM EFV model has undergone a rigorous verification
and validation process in order to build confidence that it
can be trusted when used properly with valid input data.
Developed
for the US Marine Corps EFV Program Office, OSCAM EFV is a program
specific model, building upon the fundamental structure of the
OSCAM Land model.
Prior to development of the model, it became evident that the
process used by the UK Army to support its equipment was broadly
similar to that used by the US Marine Corps. Initial development
of OSCAM EFV was therefore based on the existing OSCAM Land
model, providing a sound basis for a model tailored to the needs
of the EFV program.
HVR Consulting identified key areas where the processes associated
with the EFV program differed from those of the existing UK
Land model, therefore defining the overall scope of the problem
and understanding the processes that needed to be represented.
Following translation of their current cost estimates into OSCAM,
the EFV program office plan to employ the tool to provide life
cycle cost estimates by means of what-if drills and trade-off
studies across varying scenarios.
