Nowadays, modern manufacturing enterprises pay more and more attention to reliability in order to ensure the mechatronic product quality. Since the reliability modeling and evaluation of mechatronic product are the bases of reliability engineering, the novel system full-state model and assessment method based on meta-action are proposed in this article. First, the “Function-Motion-Action” decomposition method and meta-action definition are introduced, and based on the thought of “Top-Down,” the mechatronic product is decomposed to the most basic motion unit—meta-action unit. Second, on the basis of the fact that the reliability of mechatronic product is determined by the reliability of meta-action unit, the complete new classification method is presented. This method divides the product operation states into the meta-action unit fault state and normal state. Third, the collaborative full-state model is established for mechatronic product, the Markov process with all states is combined, the model is solved...
