The Research of Embedded Software Reliability Modeling Analysis Based on AADL

This paper proposes an analysis method of embedded and distributed software reliability modeling based on AADL. By using the key information in AADL structural model, AADL fault model is established, to describe the fault behavior of computer distributed software. On this basis, the reliability analysis is carried through the sensitivity analysis method. We analyze the reliability of the system, which can help designers to find out the key modules that affect the reliability of the system in the early stages of development and provides a strategic decision foundation to enhance the system reliability.
