knowledge based engineering (KBE) is a relatively young technology with an enormous potential for engineering design applications. Unfortunately the amount of dedicated literature available to date is quite low and dispersed. This has not promoted the diffusion of KBE in the world of industry and academia, neither has it contributed to enhancing the level of understanding of its technological fundamentals. The scope of this paper is to offer a broad technological review of KBE in the attempt to fill the current information gap. The artificial intelligence roots of KBE are briefly discussed and the main differences and similarities with respect to classical knowledge based systems and modern general purpose CAD systems highlighted. The programming approach, which is a distinctive aspect of state-of-the-art KBE systems, is discussed in detail, to illustrate its effectiveness in capturing and re-using engineering knowledge to automate large portions of the design process. The evolution and trends of KBE systems are investigated and, to conclude, a list of recommendations and expectations for the KBE systems of the future is provided. (C) 2012 Elsevier Ltd.

Design engineering - a need to rethink the solution using knowledge based engineering

knowledge-based SYSTEMS 1999年第5-6期12卷 257-267页

作者： Chapman, CB Pinfold, M Univ Warwick Ctr Adv Technol Warwick Mfg Grp Coventry CV4 7AL W Midlands England

This paper discusses the current limitations of Computer Aided Design (CAD) tools and reports on the use of knowledge based engineering (KBE) in the creation of a concept development tool, to organise information flow and as an architecture for the effective implementation of rapid design solutions. The KBE tool along with supporting analytical solutions has been applied to the Body-In-White area of automotive design. The present methods of using CAD and Finite Element Analysis (FEA) systems do not use a unified product/ process model representation and lead to the creation of separate non-relation data models that only capture the result of the engineering process. The KBE method unifies the engineering intent into a single model that allows for existing or novel design solutions to be assessed. These design solutions can then represent themselves in the correct form to the analysis systems. Automeshing is achieved using a rule-base that meshes the model with respect to the analysis solution required, materials and processes. (C) 1999 Elsevier Science B.V. All rights reserved.

International Standard Development for knowledge based engineering Services for Product Lifecycle Management

In September 2005, the international information technology standard body Object Management Group (OMG) published a Request for Proposal (RFP) for an international standard for knowledge based engineering (KBE) Services for Product Lifecycle Management (PLM). The standard aims to facilitate the integration of KBE applications in a PLM environment. KBE has been used in key engineering industry to deliver significant business benefits and has been a catalyst for changes in engineering processes. In recent years, mainstream CAD vendors begin to incorporate KBE functionalities in their solutions. PLM is evolving from the platform to manage engineering data to the repository of complete enterprise knowledge. As CAD becomes more knowledge based, the convergence of KBE and PLM is expected to happen soon. The OMG standard RFP is an action to accelerate this convergence. The RFP is the result of an international effort with a team that includes engineering end users, software vendors and researchers. This paper presents the essence and the development process of the RFP to widen the engagement with the engineering research community.

ADVANCES IN engineering SOFTWARE 2001年第12期32卷 903-912页

作者： Chapman, CB Pinfold, M Univ Warwick Ctr Adv Technol Warwick Mfg Grp Coventry CV4 7AL W Midlands England

This paper describes a knowledge based engineering system (KBES) to extend the current capabilities of automotive body-in-white (BIW) engineers. It allows them to respond dynamically to changes within a rapid timeframe and to assess the effects of change with respect to the constraints imposed upon them by other product cycle factors. The system operates by creating a unified model description that queries rules as to the suitability of the concept design and is built using a standard KBES to reduce project costs and system implementation. knowledge from expert engineers and technical literature are captured and represented within the KBE application framework.

This paper starts with an analysis of the need for knowledge based engineering (KBE) system based on typical domain-specific engineering products. It looks back the history of KBE and exams the general structure of KBE systems. It then reviews the current development, particularly the knowledge representation in a KBE system, followed by a discussion of the shortcomings regarding to the maintenance and excessive cost of integrations with other digital tools. Finally it recommends the characteristics of a genuine KBE system and the standardization of KBE applications, particularly the internal knowledge representation standards and knowledge-based system interface standards with CAx systems and PLM solutions.

1st International Conference on knowledge engineering and Ontology Development

knowledge is a vital component of engineering design. Computer systems enriched with logic and engineering knowledge can support engineering design by automating routine configuration design processes. This automation is well structured in the framework concept of a Design and engineering Engine, applying knowledge based engineering techniques. The lack of recognized development methodologies implies significant investments for the development and maintenance of Design and engineering Engines. To alleviate the required effort an ontology for engineering knowledge is being developed. To that end, a classification of configuration design processes is proposed as well as a classification of knowledge elements. The resulting knowledge repository can be considered a Domain Specific modelling Language. To validate the proposed ontology, a case study is presented, addressing an assignment problem in the field of wire harness design. Using the Domain Specific modelling Language, the source code for the product model can be generated automatically using a model-driven approach.

The Life Cycle Thinking and the knowledge based engineering approaches can be integrated in order to allow a preliminary-rough but effective Life Cycle Assessment, since the first phases of the design of an industrial product. In the present paper, we propose a general framework considering a number of different aspects, mainly concerning the manufacturing choices, but also related to the design of the product. The aim is to overcome the eco design paradox and to provide a tool supporting designer during the product concept to increase its sustainability.
