英文摘要： Geometrical Product Specification and Verification (GPS) matrix system is a universal tool for expressing geometrical requirements on product design drawings. Although commonly acknowledged by industrial users as one of the most successful efforts in integrating existing product lifecycle standards, the new generation of GPS standards are considered to be too theoretical, complex and over-elaborate for industry, especially for small medium sized enterprises (SMEs).Therefore, in order to overcome current GPS application problems and drawbacks of software packages in their practical use , a unified mathematical model and an integrated GPS expert system based on this model will be researched in this project. This unified model that contains categorical internal and external modeling diagrams, as well as a dynamic morphism mapping mechanism between them, can gracefully fuse data concept abstraction and formal method specification together based on the Category Theory. The categorical internal model focuses researches on how to completely express the complicated GPS world by using various mathematic constructs and morphisms in the Category Theory. The categorical external model is a knowledge application model, which researches on how to dynamically generate GPS knowledge from internal model by using the designed mor
