Knowledge Engineering And Computer Modelling In Cad

Knowledge Engineering and Computer Modelling in CAD covers the proceedings of CAD86, The Seventh International Conference on the Computer as a Design Tool. The book presents 49 papers that are organized into 14 parts according to their respective themes. The main themes of the conference are modeling and expert systems. Materials covering database, control, and geometric modeling are also presented. The coverage of the text includes expert systems in process planning; selections and evaluation of cost-effective CAD systems; and designing complex artifacts with the assistance of a microcomputer-based system. The book will be of great use to researchers and practitioners whose work involves the utilization of CAD.

CAD (Computer Aided Design) technology is now crucial for every division of modern industry, from a viewpoint of higher productivity and better products. As technologies advance, the amount of information and knowledge that engineers have to deal with is constantly increasing. This results in seeking more advanced computer technology to achieve higher functionalities, flexibility, and efficient performance of the CAD systems. Knowledge engineering, or more broadly artificial intelligence, is considered a primary candidate technology to build a new generation of CAD systems. Since design is a very intellectual human activity, this approach seems to make sense. The ideas of intelligent CAD systems (ICAD) are now increasingly discussed everywhere. We can observe many conferences and workshops reporting a number of research efforts on this particular subject. Researchers are coming from computer science, artificial intelligence, mechanical engineering, electronic engineering, civil engineering, architectural science, control engineering, etc. But, still we cannot see the direction of this concept, or at least, there is no widely accepted concept of ICAD. What can designers expect from these future generation CAD systems? In which direction must developers proceed? The situation is somewhat confusing.

IFIP Working Group 5.2 has organized a series of workshops extending the concept of intelligent CAD to the concept of "knowledge intensive engineering". The concept advocates that intensive life-cycle knowledge regarding products and design processes must be incorporated in the center of the CAD architecture. It focuses on the systematization and sharing of knowledge across the life-cycle stages and organizational boundaries. From Knowledge Intensive CAD to Knowledge Intensive Engineering comprises the Proceedings of the Fourth Workshop on Knowledge Intensive CAD, which was sponsored by the International Federation for Information Processing (IFIP) and held in Parma, Italy in May 2000. This workshop looked at the evolution of knowledge intensive design for the product life cycle moving towards knowledge intensive engineering. The 18 selected papers present an overview of the state-of-the-art in knowledge intensive engineering, discussing theoretical aspects and also practical systems and experiences gained in this area. An invited speaker paper is also included, discussing the role of knowledge in product and process innovation and technology for processing semantic knowledge. Main issues discussed in the book are: Architectures for knowledge intensive CAD; Tools for knowledge intensive CAD; Methodologies for knowledge intensive CAD; Implementation of knowledge intensive CAD; Applications of knowledge intensive CAD; Evolution of knowledge intensive design for the life-cycle; Formal methods. The volume is essential reading for researchers, graduate and postgraduate students, systems developers of advanced computer-aided design and manufacturing systems, and engineers involved in industrial applications.

Domain Modelling for Interactive Systems Design brings together in one place important contributions and up-to-date research results in this fast moving area. Domain Modelling for Interactive Systems Design serves as an excellent reference, providing insight into some of the most challenging research issues in the field.

This state-of-the-art book explores the concept of knowledge-intensive CAD systems. The topics covered range from ontology to knowledge representation, making it essential reading for researchers, engineers, and technical managers involved in the development of advanced applications for knowledge management, engineering design, and manufacturing.

Design and manufacturing-preparation activities can be regarded as information processing activities that, starting from the original concept of the product and the use of product models, generate detailed manufacturing control information and the framework which describes all the necessary information about the product and its processing. In order to achieve a higher level of automation for design and manufacturing processes, it is essential to analyse engineering information as transferred to and manipulated among related activities. It is also vitally important to prepare the framework which is to capture the information systematically; this is known as the engineering knowledge. It includes basic information such as dimensions, tolerances, assembling, mechanics, etc., and also expert knowledge which strongly depends on the respective engineering and product domains. This book examines the methods used in the representation and manipulation of this engineering knowledge, as well as in the generation and manipulation of product models.

Knowledge-Intensive CAD clarifies and elaborates the concepts of knowledge-intensive design and CAD. In today's advanced manufacturing environment, CAD systems should not only assist designers and engineers during product design, but also in design information for use in later stages of the process such as production, distribution and operation. This book focuses on the sharing of knowledge across life-cycle stages and organizational boundaries.
