Abstract: In order to find an optimum assembly sequence in engineering design domain, a knowledge-based virtual assembly approach was put forward. Virtual assembly design environment was also introduced, and knowledge representation models for virtual assembly rules and cases are introduced and studied respectively. A side-center virtual assembly method was applied to avoid the occurrence of assembly interference. Finally, a case was employed to demonstrate the practicality of knowledge-based virtual assembly planning.

Abstract: E-Hubs as new entrants with new business models pour into the business-to-business space; it's increasingly difficult to make sense of the landscape. Electronic hubs--Internet-based intermediaries that host electronic marketplaces and mediate transactions among businesses--are generating a lot of interest. This paper provides a blueprint of the E-Hubs arena. Conceptual specification of functional system, comprising the selection of core E-Hubs services and definition of basic hosting platform of the E-Hubs realization business development plan, Conceptual framework for Manufacturing Resource Management System designs based on E-hubs.
