Research On Product Design Process Oriented Knowledge Push

With the continuous development of enterprise informationization, knowledge plays amore and more important role in improving the market competitiveness of enterprises."Knowledge Overflow" and "Knowledge Trek" phenomena reflect that although the stockof knowledge is huge, and knowledge source is rich, but the ability of user to acquireknowledge is seriously insufficient. In view of the above problems, knowledge pushingtechnology was researched from the aspects of the knowledge push framework,multi-dimension context modeling for product design, multi-dimension knowledge pushalgorithm based on forgetting curve and the product design oriented knowledge pushingintegration technology, aimed at better application of design knowledge to product designprocess, and improving design efficiency. The main research work is as follows:(1) studied the definition, requirement, algorithm, context modeling and cases etc. ofpushing, based on which proposed the basic knowledge push framework an enterpriseimplements for product design process, and put forward three key problems in theframework: multidimensional context modeling for product design, knowledge pushcalculation method based on the forgetting curve and product design oriented knowledgepush integration related key techniques.(2) According to the knowledge push frame, product design oriented multidimensionalcontext modeling process was designed. Context of knowledge management in productdesign was analyzed in the demand, function, identification and acquiring methods. Themultidimensional context modeling in product design process was proposed, and thecorresponding multidimensional context model available for knowledge push wasconstructed.(3) Studied the key calculation methods related to knowledge push. The forgettingcurve algorithm is respectively and deeply applied to user vector model and similaritymatrices, improving the ability of knowledge push to wipe out noise data and to refine data.And on this basis put forward collaborative filtering-based knowledge push and push subengines. (4) For tight integration of knowledge push and product design, the research on thekey techniques for integrating knowledge push was conducted. Studied on vectorsupplementary model, knowledge indentifing and task context information processing toimprove quality and enhance the integration effect of push knowledge and design task. Atthe same time the knowledge push display processing techniques were studied.(5) On the basis of theoretical research, designed and developed product designoriented knowledge push system. Taking a special vehicle Institute’s oil and gas spring asthe object of study, the knowledge push function is verified.
