Modeled as a collection of inter-dependent sectors,
the OSCAM Navy model provides a structured yet flexible approach
to cost estimation. As well as access to historical data, the
models can be rapidly populated with user defined data, or a combination
of the two. Simulation runs can be carried out quickly, enabling
users to build up a series of results to reflect alternative strategies
across a range of scenarios.
Recent enhancements to the Naval suite include a robust Uncertainty
and Sensitivity suite of tools, enhanced personnel and maintenance
sectors that reflect the Navy’s paradigm shift to multiple
crews per vessel, inclusion of depot level maintenance accomplished
through the use of continuous maintenance, and expanded software
maintenance, training, and indirect cost sectors to enable maximum
modeling flexibility to the user community.
Both the Ship and Shipboard Systems model also come with an additional
add-in tool titled the Data Management Tool (DMT). The DMT allows
the modeler to create a Work Breakdown Structure (WBS) that represents
the total platform and build up maintenance requirements from
the ground up. Maintenance requirements will aggregate up from
the sub-system level and generate a platform level maintenance
requirement that can be ported into the main OSCAM tool. The DMT
is ideal for performing cost tradeoff studies between sub-system
components. For example, if a propulsion study is required, the
maintenance requirements for each option can easily and quickly
be inserted into the model for cost impact evaluation.
Another add-in, unique to the Ship model, is the Parametric Cost
Tool (PCT). The PCT is used to generate an OSCAM compliant dataset
early on in system’s life when little technical definition
exists to aid in developing a bottoms up or analogy based cost
estimate. The PCT generates an OSCAM dataset by taking at a minimum
4 user defined technical characteristics (Lightship Weight, Propulsion
Type, Mission Type, and Cost of Fuel) and applying them to Cost
Estimating Relationships (CERs) developed from data that is available
through the VAMOSC system. All PCT CER development documentation
is available in Naval Suite downloads section of the website.

In
common with the other models in the OSCAM group, the advantages
of OSCAM Navy include issues relating to the modeling approach
used, as well as the data structure and open architecture. For
