Heterogeneous Architecture-Based Software Reliability Estimation: Case Study

With growing system complication, multiple structures are constructed in software, instead of single architecture style. As a result, the traditional architecture-based models that have considered only homogeneous software behaviors are not suitable to the complex system. In this paper a heterogeneous architecture-based model is presented. In order to verify the practicability, we apply the model to estimate the system reliability of the astronautics payload communication and monitoring system (APCMS). Multiple structures are constructed in the system, L e., sequence, parallel andfault-tolerance. The study results demonstrate that the model is accurate when compared to the actual reliability. Theoretical research must be applied on actual systems to understand their applicability and accuracy.
