It is well-known that some 85% of the resources necessary to design and bring to market a product are committed by decisions taken in the first 10% of the design activity. This together with the wish to reduce further the time-to-market of high quality innovative products has increased the need for computer support at the conceptual design stage of the engineering design process life-style. This proceedings firmly focuses on the continuing research into new uses of Artificial Intelligence (AI) during the conceptual design process. It shows how novel applications of AI may be integrated with aspects of solid modelling, simulation optimisation and multiple criterion decision- making. A particular emphasis is placed on the use of AI methods in the overall design of products from major Civil Engineering structures to Consumer Electronics.

Product Data Technology encompasses the information related to all stages in the product life cycle from product design via production planning, production processes, production control etc. through the delivery and operational stages of the technical product. Product Data Technology takes a coherent, unified view of the information captured in this whole life cycle and provides methodologies to support this integrated perspective. The Product Data Technology Advisory Group (PDTAG), a Special Interest Group of the CIME Division of the Commission of the European Communities founded in 1991, has encouraged the formation of a new subseries on Product Data Technology within the existing series of Research Reports ESPRIT. This subseries will provide a depository for the important contributions made by ESPRIT projects to the evolving area of Product Data Technology, particularly also those based on STEP (ISO 10303). PDTAG is grateful to Springer Publishers for establishing this subseries which will serve to report recent international developments in Product Data Technology. The current volume describes the results of the ESPRIT Project CACID (Proj. No. 5168), dealing with the subject of computer-aided concurrent integral design. Concurrent engineering provides an important enhancement of computer-aided product design by offering a framework and methodology for the management of design projects with multiple parallel tasks. Concurrent Engineering is one of the important growth areas for Product Data Technology.

AutoCAD is the most widely used computer-aided design package in the world. Underneath AutoCAD is a powerful computing language called AutoLISP. This language is designed to automate many functions of AutoCAD. This book is a hands-on introduction to AutoLISP and its applications. AutoLISP is a unique and powerful language that allows you to write, debug, and modify programs extremely quickly, once you understand how the language itself works. Part I contains an easy-to-learn pictorial representation for data and code, a tool used to easily solve problems otherwise approached through trial and error method. Essential AutoLISP is the only book in its field that uses the pictorial representation. Part II is devoted to learning how AutoLISP processes the code entered. Part V not only explains the causes of most common error messages and how to solve them, but examines many other errors that don't necessarily give messages.

Das erste Fachgesprach "Autonome Mobile Systeme" fand im November 1985 in Karlsruhe statt. Es wurde von P. Levi und U. Rembold veranstaltet und hatte zum Ziel, die damals noch jungen Aktivitaten auf diesem Gebiet in der damaligen Bundesrepublik Deutschland zu sortie- ren und vollstlindig darzustellen. Dieses Fachgebiet hat mittlerweile einen solchen Umfang angenommen, daB von einer vollstlindigen Darstellung der entsprechenden Arbeiten nicht mehr die Rede sein kann. Neuere Fachgesprache vermitteln daher nur reprlisentive Querschnitte und bertlcksichtigen seit den beiden letzen Jahren auch internationale Beitrage. Mit der Anzahl der Beitrage wuchs auch der Fachgesprachsbeirat, ihm gehoren seit einigen Jahren die filnf Mitglieder an, die auch die Beitrage dieses Bandes ausgewahlt haben. Ferner wuchs auch die Anzahl der veranstaltenden Hochschulen an. Das Fachgesprach wurde sieben- mal in Karlsruhe veranstaltet, zweimal fand es in Mtinchen statt, wobei es 1987 mit dem Kolloquium des erfolgreichen SFB 331 "Informationsverarbeitung in autonomen, mobilen Handhabungssystemen" zusammengelegt wurde. Zu seinem lOjlihrigen Jubilaum wird das Fachgesprach dieses Jahr in Stuttgart veranstaltet. Damit verbunden ist eine Neuerung beim Tagungsband. Er erscheint erstmals in der Serie "Informatik aktuell" und solI damit filr eine verswkte Breitenwirkung unseres Fachgespraches sorgen.

What is AutoCAD? AutoCAD is the world's most popular computer-aided drafting package for the personal computer (PC). It is a fully functional 2D and 3D CAD program. Full 3D wire frame representation was incorporated in the program with the launch of Release 10 in 1988. Release 11 brought additional 3D facilities in cluding some solid modelling capabilities. These capabilities were enhanced with Release 12 of the program for DOS and Windows. Its popularity has made AutoCAD the de facto industry standard for PC-CAD with a host of other program developers providing application software conforming to the AutoCAD format. As a fully functional drafting program, AutoCAD can achieve anything that can be drawn on a drawing board. The main benefits of CAD come more from being able to edit and exchange drawing information rapidly rather than simply replacing the drawing board. Starting to use AutoCAD is a difficult step as it requires a certain amount of new skill development. Once you have made the commitment to learn how to use the program and implement it in your everyday work the benefits will soon accrue. You will quickly discover that there are many things that you can do with AutoCAD that you could never do with a drawing board. With AutoCAD your drawings become more than just black lines on a white sheet of paper. The AutoCAD drawing is a database of information."

This volume contains a selection of papers presented at the third European Computer Aided Systems Theory workshop, EUROCAST '93, held in Spain in February 1993. The workshop emphasizes interdisciplinarity with the specificgoal of creating a synergy between fields such as systems theory, computer science, systems engineering and related areas. The contributions in this volume are strongly related to current problems in CAST research. They emphasize an engineering point of view concerning systems theory. Since the computer is an essential instrument in CAST research, there are close relations to specific topics incomputer science. The papers are grouped into parts on systems theory and systems technology, specific methods, and applications.

The Product Data Technology Advisory Group, short PDTAG, was established on 30 September 1992 under the auspices of the ESPRIT CIME Division of the Directorate General XIII of the European Commission. Its goals include promoting European cooperation and improving the European infrastructure in Product Data Technology, particularly in connection with the new standard STEP (ISO 10303). The dissemination of information on Product Data Technology and on European contributions to STEP is of crucial importance to this development. The current volume is the first title in a new PDTAG subseries to Springer Publishers' Research Reports ESPRIT. This new subseries intends to form a comprehensive repository of publications on Product Data Technology resulting from ESPRIT Projects and from European contributions to standardisation based on ISO/STEP. PDTAG welcomes the opportunity to make this information more accessible under the format of a coherent subseries within the established framework of Research Reports ESPRIT. Much valuable background on the new international PDT standard can thus be found in the same collection.

Algorithms provide the basic foundation for all computational processes. This volume presents algorithms at the foundational level and also at the various levels between this level and the user application. Some of these algorithms are classical and have become well established in the field. This material is therefore a rich source of information and is still relevant and up to date. The basic primitives of computer graphics have remained unchanged: lines, circles, conics, curves and characters. This volume contains reference material in all these areas. The higher levelsof contouring and surface drawing are also well covered. Developments in hardware architectures have continued since the first printing, but the basic principles of hardware/software trade-offs remain valid. This reprint is being published as a Study Edition to make the material more accessible to students and researchers in the field of computer graphics andits applications. The continuing popularity of the original book demonstrates the value and timeliness of its contents.

Reiner Anderl The Advanced Modelling part of the CAD*I project aimed at the development of a new generation of modelling techniques as a basic functionality of future CAD/CAM systems. The methodology and concepts for advanced modelling techniques, their availability in the communication interface of a CAD/CAM system and their influence on internal interfaces in the software architecture of a CAD/CAM system are fundamental results of advanced modelling work. These results form the basis for the development of a new generation of CAD/CAM systems which are called product modelling systems. CAD/CAM systems today mainly support the geometric description of a technical part or its description as a technical drawing. Advanced geometric modelling capabilities deal with parametric design functions embedded into CAD/CAM systems. However, development strategies for future CAD/CAM systems are directed toward the following: 1. The development of product modelling systems and 2. the development of integrated systems based on CAD, CAP (Computer Aided Planning), CAM and other CIM (Computer Integrated Manu facturing) functionalities."

With the SPARC (Scalable Processor ARChitecture) architecture and system software as the underlying foundation, Sun Microsys terns is delivering a new model of computing-easy workgroup computing-to enhance the way people work, automating processes across groups, departments, and teams locally and globally. Sun and a large and growing number of companies in the computer industry have embarked on a new approach to meet the needs of computer users and system developers in the 1990s. Originated by Sun, the approach targets users who need a range of compatible computer systems with a variety of application soft ware and want the option to buy those systems from a choice of vendors. The approach also meets the needs of system developers to be part of a broad, growing market of compatible systems and software-developers who need to design products quickly and cost-effecti vel y. The SPARe approach ensures that computer systems can be easy to use for all classes of users and members of the workgroup, end users, system administrators, and software developers. For the end user, the SPARC technologies facilitate system set-up and the daily use of various applications. For the system administrator supporting the computer installation, setting up and monitoring the network are easier. For the software developer, there are ad vanced development tools and support. Furthermore, the features of the SPARC hardware and software technologies ensure that SPARC systems and applications play an important role in the years to come."

In 1984, while I was following his postgraduate course on VLSI design, my supervisor Dr. David Skellern, asked me if I was interested in investigating intelligent approaches to automatic Ie floorplanning. He told me then: "a circuit that works always looks nice, has a clever data and control flow. A fast way to look at students' Ie projects is by looking at their fioorplans.". Later, I took a course on Knowledge Engineering (KE) and Artificial Intelligence (AI) with Professor John Gero, who encouraged me to investigate this area of design automation. The resources for such development were really poor at IS&E as KE was a relatively new field of research in Australia at that time. \'Vhatever the difficulties (a good programmmer never blames his tools as David Skellern used to tell me), I undertook the investigation of Knowledge-Based approaches to Ie ftoor planning as my PhD thesis subject with the help of my supervisor and John Gero and the encouragement of all researchers at IS&E , who provided an exciting environment for my research. This volume reports the results of my research during 1984, 1985, 1986, and 1987. The voulme deals with Ie ftoorplanning from four perspectives: floorplanning strategy, Knowledge Engineering in the Ie domain, the development of knowledge-based fioorplan ning processes and new floorplanning algorithms for use in the overall strategy.

Software development environments are integrated sets of tools, techniques and processes that assist in the sys- tematic development of software products. They are intended to support all phases of the software development cycle: requirements definition, design, implementation, test, and maintenance. These Computer Aided Software Engineering (CASE) tools typically make use of graphic manipulation facilities and rely on some form of development database to exchange various types of design objects between tools. Facilitated by the availability of powerful workstations, implementations of these technologies are now within reach of every software developer. This volume presents the proceedings of a symposium organized by the GI (Gesellschaft fA1/4r Informatik), the GMD (Gesellschaft fA1/4r Mathematik und Datenverarbeitung) and ESEC (European Software Engineering Conferences). The symposium brought together application development managers and top specialists involved in the selection and introduction of software development tools, leading developers of such tools and well known authorities from the research community. The proceedings contain first-hand information on practical experiences and requirements, development directions and strategies, and key research issues and results.

In this ESPRIT research report of a group of engineers in the CAD*I project the possibility of using a database management system (DBMS) for computer aided design (CAD) purposes is analyzed and conditions are derived that enable CAD systems to manage CAD models containing increasing amounts of data and more and more intelligent relations. Today CAD models constitute isolated islands of data stored in independent files, and to create and maintain relations between pieces of information stored in several models (files) in a multi-user environment is a complex task. At a conceptual level, a relational DBMS associated with the language SQL (ISO standard) is the ideal tool to create and maintain such relations. At the implementation level, it is of the highest importance to define the optimum granularity of information to be stored in the database in order to get a good response time from such a system.
