System reliability directly affects the realization of software‐intensive system functions, which rely on both hardware and software. The operating status of hardware and software affect each other, and the continuous accumulation of their degraded performances will accelerate the occurrence of failures. However, the interaction relationship between hardware and software is often overlooked in most current research. In this paper, a new reliability analysis method is proposed for multi‐state software‐intensive systems with degradation accumulation effect and information transmission attenuation based on goal oriented (GO) methodology. First, a new function GO operator is created, and its operation formula is derived with the aid of Markov process theory. To quantify the impact of degradation accumulation on availability, non‐negative constant and random variable critical thresholds are set for the degradation state. Then, an effective optical power loss model is established to analyze the reliability of information transmission in the presence of attenuation. Next, the reliability analysis framework for multi‐state software‐intensive system is established based on the GO method. Finally, the proposed reliability analysis method is applied to the example of meter and decameter wavelength radio heliograph to demonstrate the applicability and feasibility of our work. The proposed model provides a more accurate reflection of the system reliability under actual operating conditions.

“…Among them, DFT is the most widely used in engineering, while FPN method has irreplaceable and important advantages, which make up for the deficiency of fault trees in practical application. DFT method and FPN method have achieved some research results in the field of fault diagnosis and reliability analysis of complex systems as well as their combination with each other [8][9][10][11][12][13][14][15][16][17][18][19][20][21].…”

Train communication network (TCN) is an important guarantee for the reliable and safe operation of high-speed rail train. The higher reliability of the TCN is, the safer operation of high-speed rail train will be, and the cost of overhaul and maintenance will be greatly reduced. The 250 km/h high-speed rail TCN being developed in China is the first time that the train communication Ethernet (TCE) is used as train control network. Therefore, it is of great practical significance to analyze the reliability of TCE and improve the reliability of TCN design and vehicle design. Dynamic fault tree (DFT) and fault Petri nets (FPN) are both important methods for system reliability analysis. Among them, DFT is most widely used in the field of engineering analysis. The FPN method also has its unique characteristics and advantages, which can describe fault propagation analysis and dynamic transition process in practical application. In this paper, TCE's structure, working principle, and fault mode are analyzed to sort out the relationship between complex fault events and establish a DFT with TCE failure as the top event. DFT and FPN methods were combined to better express the dynamic propagation of TCE fault and carry out the fault probability evaluation and system reliability based on the known prior failure rate. The analysis results show that improving the reliability of specified network segments of TCE is of great help to improve the reliability of the high-speed rail train.
