Knowledge Based Engineering in Complicated Product Design

摘要

Under the tendency of knowledge economy in the world, knowledge research becomes a hot subject. The analysis about the meanings, categories and characteristics of knowledge is presented at first. The concept and key techniques of Knowledge Based Engineering (KBE) are discussed. The differences and relationships among KBE, Expert System (ES) and CAD/CAE/CAPP/CAM (CAX) Systems are analyzed as well. An example on knowledge-based designing of one complicated product is provided. A product knowledge base is established by analyzing the structure and characteristics of product design knowledge. Product knowledge integration and management is fulfilled using Product Data Management (PDM) and dynamic database technique.
