The HSRN-based Reliability Analysis of Redundant Software and Hardware Integrated Systems

Xuan Hu, Jie Liu

Abstract— In the areas with high reliability requirements, the use of redundancy technology can increase multiple resources of hardware and software, and achieve reasonable management of resources, thereby improving product and system reliability. In this paper, the reliability model of redundant software and hardware integrated systems is established and the reliability analysis is performed. By constructing the hierarchical stochastic reward nets model of software and hardware integrated systems, the equivalent transformation of lower-level reliability model can be realized, and the establishment process of upper-level model can hide the internal structure of the lower-level model. In this way, the upper-level model is concentrated on the use of redundant methods, which can make the upper-level model clearer. Meanwhile, the hierarchical modelling process can reduce the state space during the reliability analysis of the upper-level model, and eliminate the need to repeat the design of the same subnet. Furthermore, taking the reliability analysis of flight control computer system as an example, the feasibility and effectiveness of the method are verified, and it also provides a basis for the reliability design of similar systems
