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 details, please click below.
