“…In general, risk features analysis only contains occurrence likelihood and consequence severity when using the risk matrix method [40], and propagation characteristic analysis is not required. However, the propagation characteristic becomes the third important feature of the configuration risks because of the serial implementations of the space station configuration and risks' close association.…”

A space station is a typical phased-mission system, and assessing its reliability during its configuration is an important engineering action. Traditional methods usually require extensive data to carry out a layered reliability assessment from components to the system. These methods suffer from lack of sufficient test data, and the assessment process becomes very difficult, especially in the early stage of the configuration. This paper proposes a reliability assessment method for the space station configuration mission, using multi-layer and multi-type risks. Firstly, the risk layer and the risk type for the space station configuration are defined and identified. Then, the key configuration risks are identified comprehensively, considering their occurrence likelihood and consequence severity. High load risks are identified through risk propagation feature analysis. Finally, the configuration reliability model is built and the state probabilities are computed, based on the probabilistic risk propagation assessment (PRPA) method using the assessment probability data. Two issues are addressed in this paper: (1) how to build the configuration reliability model with three layers and four types of risks in the early stage of the configuration; (2) how to quantitatively assess the configuration mission reliability using data from the existing operational database and data describing the propagation features. The proposed method could be a useful tool for the complex aerospace system reliability assessment in the early stage.

“…Five of their collaborators, each being affiliated with institutions in two different countries (China and other countries), were involved in seven out of their ten articles (Guo et al, 2018;Shi et al, 2018a;Shi et al, 2018b;Shi et al, 2019;Wu et al, 2014;Wu et al, 2016;Yu et al, 2018). The reason why these scholars are affiliated with two institutions is that they carried out academic exchanges and…”

“…Therefore, combined with the characteristics of CNC machine tool fault diagnosis, the weight factor is added on the basis of the traditional FMEA method and the GRE is proposed. Compared with the traditional FMEA method, the GRE can not only identify the most vulnerable components in the system by analyzing various data of fault, but also consider the effect of three variables on the whole, as shown in formula (1). DSM method proposed by Steward is widely recognized for identifying the coupling relationship between units [36].…”

“…Meanwhile, there is an indeterminate coupling relationship between subsystems and subsystems, or between units and units, thus forming a complex coupling propagation process, which brings certain difficulties to product design engineers. Commonly used reliability analysis methods include FMEA [1][2][3], FTA [4,5], Bayesian [6,7], Markov [8,9], and Petri net [10,11]. These methods mainly judge fault behavior based on single index such as failure rate, risk value, and fault propagation probability, and they analyze each event as an independent event.…”

A comprehensive fault analysis of CNC machine tool is conducive to improving its reliability. Due to the highly complex structure of CNC machine tool, there are different degrees of coupling relationship between faults. However, the traditional fault analysis methods (FMEA, FTA, etc.) for CNC machine tool do not solve this problem perfectly. Therefore, we propose a coupling fault propagation model based on meta-action. First, in order to simplify the structural complexity of CNC machine tool, the “Function-Motion-Action (FMA)” decomposition structure is used to decompose the product function into simple meta-action, and the numerical matrix is used to quantify the coupling relationship between the meta-actions. Then, based on the fault transfer characteristics of meta-action, the fault propagation model is established, and the global risk effect (GRE) is combined to realize the comprehensive evaluation of the risk criticality of meta-actions. Finally, the rationality and validity of the method are verified by the case analysis of the automatic pallet changer (APC) of computerized numerical control (CNC) machining center.
