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.
Networked manufacturing is a trend of reciprocating pump industry. According to the enterprises' requirement, the architecture of networked manufacturing system for reciprocating pump industry was proposed, which composed of infrastructure layer, system management layer, application service layer and user layer. Its main functions included product data management, ASP service, business management, and customer relationship management, its physics framework was a multi-tier internet-based model; the concept of ASP service integration was put forward and its process model was also established. As a result, a networked manufacturing system aimed at the characteristics of reciprocating pump industry was built. By implementing this system, reciprocating pump industry can obtain a new way to fully utilize their own resources and enhance the capabilities to respond to the global market quickly.
