“…Knowledge-based engineering (KBE) approaches are used in many CAx systems to support decision making, such as functional design, geometric constraint solving, parametric design, assembly oriented design, feature recognition, determining tooling components or layout, and process planning Lee and Kim 1996;Myung and Han 2001;Zhang and Xue 2002;Zha et al 2001a,b;Henderson 1984;Lee et al 1997;Mok et al 2001;Sormaz and Khoshnevis 1997;Park 2003;Chen et al 2006). KBE approaches provide a better way than pure geometric modeling to embed engineering intent during product development processes.…”

With widely used concurrent and collaborative engineering technologies, the validity and consistency of product information become important. In order to establish the state of the art, this paper reviews emerging concurrent and collaborative engineering approaches and emphasizes on the integration of different application systems across product life cycle management (PLM) stages. It is revealed that checking product information validity is difficult for the current computer-aided systems because engineering intent is at best partially represented in product models. It is also not easy to maintain the consistency among related product models because information associations are not established. The purpose of this review is to identify and analyze research issues with respect to information integration and sharing for future concurrent and collaborative engineering. A new paradigm of research from the angle of feature unification and association for product modeling and manufacturing is subsequently proposed.Keywords Concurrent and collaborative engineering · Feature-based design and manufacturing · Product life cycle modeling · Information validity and consistency

“…It also enables the project co-ordinator to specify the ontology within the knowledge base, thereby standardizing the nomenclature and vocabulary used by all persons entering or modifying project information. There are already some implementations of rule-based expert systems to aid in the definition of designs using lifecycle information as 'features ' (Esterline et al 1993, Zhang andXue 2002). These however, like CADET (Rogers and Huxor 1998), do not include feature geometry or machining features.…”

Abstract. Product Data Management (PDM) systems and their offspring, Collaborative Product Development and Product Lifecycle Management technologies, aim to bring engineering enterprises together, allowing seamless interoperability between different departments and throughout the extended enterprises. However, there are a number of shortcomings in the current crop of commercially available systems, such as the lack of design knowledge sharing, links with Enterprise Resource Planning systems, knowledge management tools and a generic standard for PDM system implementation. This paper presents a proposed software solution to some of the above problems. In particular, the paper describes methodologies being developed that are aimed at overcoming the lack of analysable product information at the conceptual stage of product design and manufacturing evaluation, along with the integration of such a concept design tool within a distributed environment. A leading PDM system is used to manage all the information and knowledge that is made available to internet/intranet users in a controlled manner. The international standard for exchange of product data model (STEP) is implemented to enable the integration of the design environment with manufacturing and enterprise resource management systems. In addition, the paper also introduces three other recent/ ongoing projects, being carried out at Cranfield University, in the application of PDM, knowledge management and STEP standard for integrated manufacturing businesses.

“…Distributed collaborative design has also received much attention recently in CAD field [2,3], and grid computing is incorporated into product design [4]. At the same time, more sophisticated programming APIs to CAD systems and Integrated KBE/CAD systems [5] are making possible customization of these systems so that modeling activities can be driven by functional inputs rather than generic modeling commands. These are opening the door to the integration of Pay-for-Use techniques with CAD systems.…”

Abstract.An agent-based framework was proposed for pay-for-use design applications. Under the framework 3D CAD models become commodities independent of the CAD systems in which they are created. In this way a user can easily shop around the Internet for the 3D models without the cost of purchasing or maintaining CAD software. In the paper the architecture of the framework was provided first. Secondly a procedural modeling algorithm which enables the framework to create the neural model according to functional and/or structural inputs specified by the user was presented. Then a model mapping method was advanced to translate the neural model to a set of CAD modeling API's. Finally two practical examples were illustrated, which showed the feasibility of the methodology presented in the paper.
