“…F are the scores corresponding to good, medium, and poor in the fuzzy evaluation set of the state variable, respectively. The score value needs to be determined according to the actual operating environment of EPOCN [17]. In order to improve the evaluation accuracy, the exponential scaling method is used to scale the importance of different state variables included in the reliability assessment indicator b of EPOCN.…”

The reliable and stable operation of Electric Power Optical Communication Network (EPOCN) is the basis for the optimization of distributed energy management. How to evaluate the operation reliability of EPOCN devices and carrying reliability remains a challenge. In this paper, we firstly propose a digital twin-based two-dimensional multi-level reliability assessment indicator system of EPOCN, which consists of device reliability and service reliability. Secondly, an improved fuzzy hierarchical reliability assessment method for EPOCN is proposed to assess the reliability level of EPOCN by scoring each level. Finally, an example is given to verify the superiority of the proposed technique in reliability indicator processing, which can effectively reduce the influence of subjective factors of evaluators and objectively reflect the reliability of EPOCN.

Motion is one of the most basic forms of mechanical products, which directly determines the performance stability and function realization of products. In this paper, a reliability allocation method for mechanical products is proposed, which takes the meta‐action with motion characteristics as the allocation granularity unit, and fully considers the performance factors and failure correlation of the meta‐action. Firstly, the function‐motion‐action (FMA) decomposition method is used to establish the decomposition model of mechanical products to determine all the meta‐actions that realize the function of products. Secondly, four factors that affect the reliability of the meta‐action are introduced, namely sensitivity, severity, potential improvement, and dynamic performance, and the comprehensive allocation weight model of meta‐actions is established. Furthermore, to solve the deficiency of the traditional failure independence hypothesis, Copula theory is used to establish the reliability allocation model of the meta‐action system. Finally, a numerical control turntable is taken as an example to illustrate the applicability of the method. The results show that the reliability allocation value of the proposed method is significantly lower than that of the traditional method when the reliability index of the product is guaranteed, which provides theoretical guidance for the reliability design of mechanical products.
