“…Failure propagation analysis model based on graph theory is divided into two types, namely, tree and graph, combining multiple reasoning methods to analyse failure propagation mechanism. [22][23][24][25] This method is mainly used for complex systems with clear logic and clear failure mechanism. However, when the system scale is huge and the relationship among the factors in the system is markedly complicated, the establishment of the corresponding model is challenging and cumbersome.…”

To improve the rationality of failure diagnosis, this research uses hypergraph theory as basis in proposing a method of analysing failure propagation behaviour to study the failure propagation mechanism from the system perspective. A hierarchical structure model is constructed by failure correlation analysis, matrix transformation and decomposition. The probability of failure is determined by considering the influence of multiple truncation data. On this basis, hypergraph theory is used to calculate the one-step and cumulative coefficient of failure propagation and diffusion. The influence degree of failure is calculated by integrating the edge betweenness. Using the influence degree of failure as an indicator, failure propagation and diffusion behaviour are analysed, and critical failure nodes and paths are identified. Lastly, a machining centre is used as an example for specific application. The results are compared with the ranking results of critical failure propagation paths determined by other methods, and the effectiveness of the proposed method is verified.

“…With the continuous development of big data and network information technology, knowledge-based fault diagnosis has apparent advantages due to its ability to process knowledge. There are several typical fault diagnostic methods based on knowledge, i.e., pattern recognition [6], artificial neural network [7], fault tree [8], fuzzy theory [9], expert system [10], or graph theory model [11].…”

Newly developed equipment is occasionally disturbed by unknown faults during operation; however, it is difficult to diagnose unknown faults based on existing fault diagnostic models or knowledge. In addition, it is time-consuming to frequently and interactively check information related to a certain fault from numerous manuals. To address the maintenance and troubleshooting of faults, this paper develops an innovative method based on integrated information and system principles. Multi-source, distributed, and heterogeneous information integration methods based on ontology and ant colony are presented, and an information integration model based on system principles and graph theory is established. A theoretical system based on the information integration model is then designed and developed. To verify the effectiveness and the feasibility of the above methods and applications, the developed methods are applied to an air source system. The results show that the developed theories support the fault diagnosis of newly developed equipment and advance the efficiency of maintenance and troubleshooting.

“…Researchers propose a fault diagnosis approach that uses a digraph model for the automobile system. 23 The approach automatically constructs the fault tree and reduces the time cost of fault tree building. Nevertheless, the aforementioned method utilizes a static fault tree, which cannot capture a dynamic fault behavior.…”

The system structure of train–ground wireless communication systems (TWCSs) is extremely complicated due to the use of fault tolerant technology to improve their performance. This complex structure raises several challenges in fault diagnosis for TWCSs, such as epistemic uncertainty, dynamic fault behaviors, and common cause failure (CCF). A fault diagnostic system is proposed to deal with these challenges based on Petri nets and gray relational analysis in this paper. Specifically, the fuzzy analytic hierarchy process is used to evaluate the failure data of components to handle epistemic uncertainty. Furthermore, the dynamic fault tree of TWCSs is established and converted into a generalized stochastic Petri net to calculate several reliability parameters used for fault diagnosis. Besides, a β factor model is employed to resolve the problem of CCF in TWCSs. In addition, Birnbaum importance measure (BIM), risk achievement worth (RAW) and test cost are considered comprehensively to obtain the optimal diagnostic sequence using an improved gray relational analysis. Finally, a numerical example is presented to demonstrate the efficiency of the proposed fault diagnostic system.
