[0043] In order to understand the present invention more clearly, the following will further discuss the present invention in detail in combination with the accompanying drawings and the examples completed by the inventor according to the technical solution of the present invention.
[0044] 1. Define non-standard knowledge granularity
[0045] The present invention adopts the triplet (K, F, Γ) to formally define the knowledge granularity of mechanical product design, wherein: K represents all design knowledge domains involved in the product specification, and the set of design knowledge considered. F is an attribute function, which is defined as F: K → y, where y represents the attribute set of design knowledge. Γ represents the structure of the domain of design knowledge, which is defined as the relationship between various elements of design knowledge in the domain of design knowledge.
[0046] 2. Construct a calculation model for the granularity division of non-normative ...
