“…Then, Li et al [28] and Ran et al [29] presented the definition of the meta-action: the action that has the relatively independent controllable and analyzable structure, has the ability to achieve a certain motion target or to achieve a certain goal, and cannot be decomposed into other actions. Zhang et al [30] revised the definition of meta-action as the elementary mode of motion that can transmit the movement and momentum in a mechanical system. They limited the application of meta-action in mechanical system and defined meta-action unit (MU).…”

Fault analysis activity is very important for a flexible manufacturing cell (FMC) in the development phase. Fault tree analysis (FTA) and fault mode and effects analysis (FMEA) are widely used for fault analysis. However, they are time-consuming and expensive when fully implemented. In this paper, we propose an improving hybrid multilevel FTA-FMEA method that is the combination of the above two methods. The proposed method has a clear three-layer analysis structure. In the first layer, a system FTA of the FMC is performed to determine the functional fault modes. Then, FMEA is conducted to examine them and the key functional fault modes are selected by criticality analysis. In the second layer, we perform the FTA of the determined key functional fault modes to find out the meta-action/component fault modes. The bottom events of fault trees in this layer show differences due to the subsystems with different features. Same as the first layer, FMEA is conducted subsequently and criticality analysis is also used to determine the key meta-action/component fault modes. In the last layer, we perform the FTA of the determined key meta-action/component fault modes to find out fault causes. Then, the key fault causes are determined by criticality analysis. Risk priority number (RPN) is usually used to determine the priority ranking in criticality analysis, while its calculation way is slightly naïve. In this paper, we use the technique for order preference by similarity to ideal solution (TOPSIS) method to examine the priority ranking of fault modes/causes. Moreover, we consider the correction cost as the fourth indicator to assess the priority. The improving fault analysis method can not only help designers better understand the new FMC but also help decision makers make better decisions. At last, a real FMC as a case is presented to illustrate the proposed method. INDEX TERMS Flexible manufacturing cell, fault analysis, FTA-FMEA, TOPSIS, meta-action.

“…Thus, the mechanical system can be decomposed into a series of meta-action units (MUs) in structure. According to [30], a meta-action unit in general consists of five elements: input part, middle part, strut member, fastener and output part. The input part and output part are the key elements for MU.…”

“…At present, the research on meta‐action unit has been relatively mature, and some achievements have been achieved, such as Refs. (25–30). In order to eliminate the early failure of electromechanical product as much as possible before it leaves the factory, it is necessary to establish a reasonable failure elimination system.…”

Frequent early failures have been the key factor restricting the reliability improvement of electromechanical product, and also reducing its market competitiveness. Most of the current early failure elimination methods are passive elimination technologies after a failure. Their purpose is to quickly restore the production capacity of products, which is mainly used to improve the reliability of the products, and cannot fundamentally improve the quality of the manufactured product. To address those problems, this paper first analyzed the causes of early failures in the production stage of electromechanical product, and studied the corresponding early failure elimination mechanism; second, according to the FRACAS (Failure Report Analysis and Corrective Action System), an early failure elimination method for electromechanical product was proposed based on the meta‐action unit; finally, in order to ensure the smooth implementation of early failure elimination measures, a set of early failure active elimination guarantee management system was established. In addition, this paper also introduced the specific implementation process of the proposed method. The proposed method is applied to engineering, and the results verify its correctness. The proposed method provides a theoretical basis and technical support for the elimination of electromechanical product early failure.

“…Therefore, it can be concluded that the failure of electromechanical product's function and performance is ultimately caused by the failure of mechanical parts' motion state. 1,[13][14][15] All the parts used to realize a meta-action can be treated as a whole (meta-action unit) according to the concept of meta-action unit, which can simplify the analysis process and refine the analysis results. 11 The failure of meta-action is the most direct manifestation of electromechanical product failure.…”

“…Meta-action and meta-action unit were first put forward by our team, and some achievements have been achieved, such as literature. 1,[13][14][15] All the parts used to realize a meta-action can be treated as a whole (meta-action unit) according to the concept of meta-action unit, which can simplify the analysis process and refine the analysis results. Reasonable metaaction decomposition method and meta-action unit separation criterion are beneficial to the subsequent analysis of quality characteristics based on them.…”

The current decomposition methods are not suitable for electromechanical product; the smallest decomposition units obtained by these methods are static parts or components, which cannot reflect the characteristics of electromechanical product that ‘action determines motion, and motion determines function'. Meta‐action is the smallest action to realize the function of electromechanical product, and it is reasonable to regard meta‐action as the smallest decomposition unit of electromechanical product. Meta‐action unit is the smallest structural unit to ensure the normal operation of meta‐action, and it is also the smallest carrier of electromechanical product quality characteristics. Meta‐action unit modeling technology is the basis of other subsequent research, so it is necessary to study it. In this paper, detailed criteria for meta‐action decomposition and meta‐action unit separation are formulated, and the standardized structural model, symbolized conceptual model, and assembly model of meta‐action unit are also studied, which provide a basis for mechanical, kinematic, and failure mechanism research of electromechanical product. A CNC (computer numerical control) machine tool made in China is taken as an example for meta‐motion decomposition and meta‐action unit modeling, and the results verify the applicability and correctness of the method proposed in this paper. The proposed method is also applicable to other types of electromechanical product.
