Embodiment Construction

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0038] Automotive engine design is a typical complex product development process in the electromechanical field. Although the engine design technology is quite mature, due to the large number of engine parts and the relatively complicated design process, the design process still requires intensive design knowledge as support. As the market's demand for environmentally friendly products continues to increase, companies need to develop more low-carbon, high-efficiency products to cope with fierce market competition. This patent takes the construction of a complex network of engine green design knowledge and the analysis of the impact of changes as an example to verify t...

Abstract

The invention discloses a knowledge change propagation model construction method, which comprises the following steps of: taking different knowledge units in a product as nodes of a network, taking amembership relationship of the knowledge units as edges of the network, taking all the edges as undirected edges, and taking the weights of the edges as correlation coefficients among the knowledge units, thereby forming a weighted undirected network. A green design knowledge network model is constructed on the basis of a weighted complex network, and a preprocessing method is provided for subsequent knowledge processing work.

Description

technical field [0001] The invention relates to the field of knowledge network model building, in particular to a method for building a knowledge change propagation model. Background technique [0002] Product green design uses a large amount of design knowledge at every stage of design activities, however, during the design process, engineers usually spend more than 50% of their time searching for the correct information in highly diverse and unstructured knowledge resources. Therefore, effectively storing, managing and retrieving design knowledge is the main measure for enterprises and industries to reduce product development life cycle time and cost, and improve product development quality. In view of the problems of fragmented knowledge points that are difficult to understand and lack of connection, how to mine the relationship between knowledge units and how to build a product design knowledge resource network have also become hot research topics for many scholars.
