A knowledge push system as a proactive method of knowledge management, and is an effective way to push knowledge to designers in the product design process. Knowledge push can help to improve design efficiency and quality, but the knowledge pushed to designers is less applicable in engineering scenarios. To improve the quality of knowledge push, we propose the trust-aware and item-cluster strategies to extract the two nearest neighbors of the designers and the design knowledge. Next, we adapt a fusion model for the two nearest neighbors, which is solved based on the gradient descent algorithm. Finally, the rating prediction that the designer gives to the knowledge component is the decision point of the knowledge push system, where we propose our final hybrid knowledge push method. A knowledge push system of CNC machine tools design is used to confirm that our method outperforms the other widely adopted methods.

一种面向产品设计的基于信任感知和项目集群的混合知识推送方法

知识推送系统作为一种主动的知识管理方法，是在产品设计过程中向设计师推送知识的有效方式。知识推送有助于提高设计效率和质量，但推送给设计师的知识在工程场景中的适用性较差。为了提高知识推送的质量，我们提出了信任感知和项目集群策略来提取设计者的两个最近邻和设计知识。接下来，我们为两个最近的邻居调整融合模型，该模型基于梯度下降算法求解。最后，设计者对知识组件的评分预测是知识推送系统的决策点，在这里我们提出了我们最终的混合知识推送方法。
