The cost and schedule required to design and develop modern computer based systems has grown dramatically over the past decade. Advanced system engineering development methods and automation techniques are required to manage the complexity inherent in the design of large complex computer based systems to provide an efficient means for evaluating various requirements options. O 3 ML is an approach, to model complex software system using a sound software architecture for systems analysis and design, which is centered upon the creation of a system prototype with an integrated design requirements and simulation framework. This methodology supports the prototyping of complex computer based systems by providing: (a) a multi-domain approach to capture architectural complexity of real-world systems; and (b) a mechanism for simulation of the conceptual, functional and implementation aspects of the design and requirements captured.
