An Ontology-Based Design Knowledge Model For The Construction Machinery

In this paper, we investigated the knowledge modeling and proposed an ontology-based descriptively-logic theory using fuzzy interval in order to support the management and re-usage of the knowledge of design. We also established the methods to classify and present the concept-design knowledge and developed an ontology-based model presenting the knowledge of design as well as a model for modeling cycles. We further applied these methods and models to develop a specific ontology-based design-knowledge model and At last the practicability and validity of these methods are validated in the management system of design knowledge for the construction machinery.
