Research on Uniform Product Development Model

To improve knowledge management and service levels, and achieve integration of software used in the whole product development process are research purposes here. Existing problems in current researches of non-semantic and semantic models are analyzed. Product development process itself, i.e. origin of semantic information of product, is studied wholly as the research object. Through research on design methodology, existence of uniform product development model (UPDM) and its value is proved to be true. Two points about significance of the ontology applied in engineering field is introduced, and adequate cause in using Ontology to express UPDM is given. Framework of UPDM, which includes two parts, i.e. product development ontology model (PDOM) and product development evaluation model (PDVM), is introduced in detail. PDOM and PDVM are constructed by using some concrete theories of Design Methodology and OWL (Web Ontology Language). This model has been successfully used in knowledge integration in a research institute.
