Abstract
This paper describes a research programmeto construct a Model-Based Systems Engineering (MBSE) methodology thatsupportsacquiringorganisations in the early stages of Off-the-Shelf (OTS) naval vesselacquisitions. Astructured approach to design and requirements definition activities hasbeen incorporated into the methodology to provide an easily implemented, reusableapproach thatsupportsdefensible acquisition of OTS naval vesselsthrough traceability of decisions. The methodology comprises two main parts.Firstly,a design space is developed from the capability needs using Set-Based Designprinciples, Model-Based Conceptual Design,and Design Patterns.A key idea is to employ Concept and Requirements Explorationto trim the design space to the region of OTS designs most likely to meet the needs. This region can be used to specifyRequest for Tender (RFT)requirements. Secondly, the methodology supports trades-off between the OTSdesign options proposed in the RFT responses using a multi-criteria decision makingmethod.The paper includes anexampleimplementation of the methodology for an indicative Offshore Patrol Vessel capability.
