Framework tools for modelling and simulation in an integrated design environment

System behaviour arises as a direct result of the interactions/interfaces which exist between components. While many of these intercomponent dependencies are easily identifiable, for example, those which arise as a direct result of inheritance, many others are obscure, often occurring as a result of technical interactions among remote entities. The identification and management of system interactions forms a major part of the system engineering practices for system architecting, but methodologies for effective identification and management of interactions arising as a result of technical interfaces is still problematic. The paper will present a methodology which may be applied in order to develop a technically-based architecture which identifies analysis dependent system linkages, demonstrating the effect of analysis fidelity on the system design applied to the aircraft system.
