Product Configuration Knowledge Expression Based on Ontology and Tabular Layouts of Article Characteristics

摘要

Product configuration design is a key technique for mass customization. The management and organization of configuration knowledge are very important to the validity and efficiency of configuration design. With the increasing of parts' number and design complexity, the volume of configuration knowledge database expands rapidly, and the reasoning efficiency of configuration design is slow down rapidly. To solve above problems, take master structure model of configuration design into account, a method of product configuration knowledge expression based on ontology and tabular layouts of article characteristics (TLAC) was proposed. Product family based configuration model wais described using TLAC for those standardization parts and components. Configuration knowledge was expressed with ontology. The knowledge of non-standardization parts was integrated into extended TLAC. This method describes product configuration knowledge database effectively and facilitates sharing and reuse of domain knowledge.
