A knowledge service framework for product-design activities

In order to improve the utilization ratio of knowledge and make the knowledge rise in value, a framework of knowledge service for design activities is proposed. Firstly, a product design knowledge representation model is proposed according to the characteristics of design knowledge, and then a knowledge service model based on semantic space is given. Then a method of knowledge service matching is proposed based on the knowledge requirements analysis. Finally, these approaches are used in a knowledge service system for military-vehicle design validating its effectiveness and feasibility.
