The UK Land model provides a generic representation of the business processes present within land systems.

Through the process of workshops comprising subject matter experts and experienced cost analysts, the structure and behavior of land based systems have been defined prior to translation into a simulation model at the quantitative level.

A Data Management Tool (DMT) for the OSCAM Land model has also been developed, enabling maintenance philosophies to be applied to component level data within a work breakdown structure prior to simulation. The DMT can also be used to analyse key cost drivers at a sub-system level.

In addition, the 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 Defence Procurement Agency's Pricing and Forecasting Group (Cost Forecasting), OSCAM Land has been employed on a number of Ministry of Defence programs, including Future Combat Light Vehicle (FCLV), where it is being used to determine the impact of Contractor Logistics Support trade-off studies. In addition, the Terrier program is using the Data Management Tool in order to receive component level maintenance data from product suppliers, prior to performing scenario analysis. Use of OSCAM has enabled scenario dependent modeling of O&S costs, using not only user defined and historic data, but also through the amalgamation of data produced in third party staffing level, logistic support and spares modeling tools.

Training courses on OSCAM Land are being planned for new staff members at the Defence Procrurement Agency's Pricing and Forecasting Group to increase their user base. As a result of feedback from people on these courses and from current users, further enhancements and updates to the software will be implemented.
