Research on Reliability Evaluation Method of Core Processor Software System Based on Component

The integrated electronic information system based on the core processor uses a large number of components which have been finalized or commercially developed, and the system structure is so complicated that common reliability evaluation methods cannot be directly applied to the system. To solve the problem of reliability evaluation of this kind of software system, this paper proposes a reliability evaluation method of core processor software system based on component. Firstly, the core processor software system is analyzed by using the method of system structure to determine the composition form of each component in the system. Then according to the condition of components, reliability evaluation model set will be confirmed and optimized. Finally, the reliability evaluation model of the whole system will be structured and verified. The results showed that the proposed method can achieve a good assessment of the reliability of the software system.
