Integrated System Design And Evaluation Based On DoDAF

An important and complex issue in architecture design of integrated complex systems is system evaluation. This thesis describes the application of structured analysis method in the architecture design, and how to derive an executable model from architecture products, based on which presents an method to evaluate the dynamic performance and effectiveness of the designed system, and the approach for system capability evaluation.The thesis firstly introduces DoDAF standard and most popular structured analysis method and object-oriented method, then describes the basic processes of the architecture design consisting with the DoDAF standard based on the structured analysis method, mainly focus on the development of functional architecture;Then, this thesis introduces the Colored Petri Net to supply a gap that the static model can't reflect the dynamic performance of the designed system, which is an executable model. The emphasis of this part is how to convert the designed static model into the CPN model.The topic of this thesis is the system evaluation—measure of performance, effectiveness evaluation and capability evaluation. First, System Efficiency Analysis technology is introduced, which carries on a system efficiency analysis through comparing the mission attribute with system attribute on an universal space. Then the paper introduces the concept of capability, the development and evaluation of capability based on system-action metrics, mission-system analysis and capability maturity model.Finally, an Expedition Strike Group is illustrated as an example to explain how to build and evaluate the system architecture with the method mentioned above.
