    Abstract:

    This paper proposes a strategy driven approach to modeling and analyzing reliable embedded systems according to their characteristics. Petri nets are used as the formal description language for embedded systems, which formally specify embedded system’s elements such as equipment, computing, physical interaction, components, and communication processes. This research studies reliability assurance strategies for embedded systems by analyzing various fault types and their characteristics. An aspect-oriented method is used to extract reliability related concerns. A complete embedded system model is obtained by constructing reliability aspect models and then applying the weaving mechanism to dynamically combining components and aspects. The effectiveness of reliability assurance strategies is analyzed based on the theories of Petri nets. A case study demonstrates that the approach can simplify design and modeling processes of embedded systems and contribute to improving its quality.
