Welcome to UCI, the Orange County campus of the University of California. Nearby are Huntington Beach, Newport Beach and Laguna Beach, which combine to create the world's view of life in the Southern California.
This year seven technical committees from the Systems and Design Group of ASME have combined efforts for this conference, five representing the Design Engineering Division and two representing the Computers in Engineering Division. Just short of 600 papers were reviewed and 480 were accepted for presentation and publication in the Proceedings. These have been organized into 12 parallel sessions running for three days.
A CD-ROM format for the Proceedings has been adopted this year for the first time. This has allowed an expansion in the size of the papers from six to twelve pages as well as the inclusion of full color figures and photographs. A book of Extended Abstracts has been prepared which provides rapid reference to specific papers. The UCI copy center, "The Clone Factory," is prepared to print any of the papers from the CD-ROM for personal use at the cost of copying.
In addition to the papers sessions, the conference includes keynote lectures on topics of fundamental concern to design and computer applications in engineering. Also, a tutorial program, exhibits and demonstrations, a companion program, and social events have been organized to complement the technical program.
The organization of this conference has required hard work and coordination by many individuals. My sincerest thanks must first go to Phil Doepker, chair of the Design Engineering Division, who played a important role in facilitating the many new ideas intended to enhance the conference experience. Next my deepest gratitude goes to the four professionals, two from ASME and two from UCI, who brought these ideas to reality: Susan Smith, Cynthia Clark, Carolyn Hunt and Debbie Hart.
These individuals are the tip of the iceberg, there is also the Conference Planning Committee made up of past, current and future DETC conference chairs, chaired by Steve Velinsky, who reviewed and advised on the budget and planning process. Then comes the Conference Organizing Committee made of the seven individual conference chairs who worked diligently with me on all aspects of the program and events. And there is Eugene Fichter's Technical Program Committee made up of the individual papers review chairs who made sure each each paper was reveiwed and assembled them into sessions. Next there is the Local Arrangements Committee who oversee all the details of the conference activities. This committee includes my colleagues from UCI, Derek Dunn-Rankin, Jim Bobrow and Ken Mease, who ahve generously committed time and effort toward our success though they are not usually involved in DET Conferences. Thank you all for your work on behalf of this conference.
I am also grateful for the efforts of the associate editors, subcommittee chairs, and paper reviewers who supported the individual program and papers chairs. And, finally, we must all express our appreciation to the authors themselves, whose commitment to excellent research make this the premier venue for the exchange of scientific and technical knowledge in design and computer use in mechanical engineering.

The papers which have appeared in this CD-ROM proceedings were presented in the 22nd Annual ASME Design Automation Conference held in Irvine, California, August 18-22, 1996. This conference was sponsored by the ASME Design Engineering Division and was organized by the ASME Design Automation Committee.
The goal of the ASME Design Automation Conference is to provide a forum for the exchange of technical ideas and presentation of high quality papers in the area of mechanical and structural design automation. This year, through the efforts of a team of dedicated subcommittee chairpersons that included Bert Bras, Mark Ganter, Jeff Ge, Hae Chang Gea, Brian Gilmore, David Hoeltzel, Mark Jakiela, Madara Ogot, Jagannatha Rao, John Renaud and Duane Storti, we were able to continue the growth and vitality of the conference. They are to be commended for their fine work.
The conference had a total of 136 submitted papers, of which 64 papers were from outside the U.S., with 107 papers accepted (an overall acceptance rate of 78.7%) for publication in the proceedings. These papers were mainly in the areas of optimum mechanical and structural design, robust design, rapid prototyping and CAM, tolerance modeling, robotic manipulators and multibody systems, dynamic modeling and simulation, finite elements, geometric modeling, manufacturing systems and other areas related to design automation.
In acknowledging the help of a number of individuals, our special and sincere thanks go to Mike McCarthy who was the General Conference Chair and must be credited with the success of this and other Design Engineering Technical Conferences (DETC) which were held at the same time, to Eugene Fichter who was the Program Committee Chair of the DETC and helped us in several occasions with our conference related needs. Special thanks also go to Brian Gilmore who shared with us his experience from the past conferences and advised us with planning of this conference. We would also like to thank Michael Wengenroth who processed, in a very reliable manner, the administration tasks in connection with European submissions.

Welcome to the 8th International Conference on Design Theory and Methodology! This conference focuses on methodologies to better enact the design process, theories on how people and machines design so as to better support the development of methodologies and automated design tools for design practice, and knowledge about design to help teach the design process to engineering students. This year's conference is rich with papers introducing new concepts about the design process, addressing approaches to product design, design in industry, team interaction through the design process, decision making, design conceptualization, and issues in life-cycle design. Papers range from the applied to the theoretical, merging long-term research issues with new knowledge that can be used in the design process today.
The high quality of the papers included in these proceedings is indicative of the maturing of the field. Over the eight years of this conference the numerous, sometimes disparate, ideas have provided for what is emerging as a foundation of knowledge for applied and theoretical methods in design. This year, as with past years of the conference, papers have been solicited in design management, cognitive design theories, product development methods, concurrent engineering, life- cycle design, robust design, design methods and models, QFD, design teams, innovative design, design representations, design for manufacture, design histories, design for quality, improved productivity methods, design tool development, design education, computational methods of design, and constraint management. Together these papers contribute to an exciting and significant area of engineering practice and research.
The conference could not have been realized without the contributions of the authors; over 80 excellent papers were submitted for this year's conference making it a difficult process for the selection of those included in the proceedings. Many thanks to all of the reviewers who worked hard to determine the most appropriate and highest quality papers submitted. Particular thanks to the review coordinators: Erik Antonsson, Alley Butler, Susan Carlson, Steve Eppinger, Susan Finger, Spencer Magleby, James Oliver, Kevin Otto, Jim Rinderle, Roy Samras, Jami Shah, Linda Schmidt, and Anna Thornton. These people especially worked hard to coordinate the review process. Finally our thanks to the ASME community for their continued support of the DTM effort.
We are excited about this year's conference. We hope these papers will provide you with new knowledge and motivate you to develop new ideas for your own work, be it in research or design practice.

The series of conferences on the Flexible Assembly Systems is organized by the ASME Design Division with an objective to serve the research and the application needs of the manufacturing industry. Assembly of a product is the last leg in manufacturing. It is the most fundamental process from the overall view point in manufacturing. Depending upon the production volume, product variation, and complexity of the product assembly, an industry is required to select one of the three available modes of assembly: Manual assembly, flexible assembly and automation in assembly. The assembly manufacturing science and technology is quite often vendor driven. The assembly machines, system configuration, process logistics, material handling, storage, retrieval and feeding of parts, etc., serve as the primary components of the assembly process and technology. Part design and design for assembly add to the complexity of the problem. Inspection and testing for quality, functionality and assurance are the added features in the research towards developing an assembly process.
The conference is high lighted with the formal presentations of the technical papers and panel sessions to understand the research issues and industry needs in flexible assembly systems, their design, control and logistics.

In this tenth year of its existence, the Engineering DataBase Program continues to grow in importance as companies identify the limitations due to the explosion of information storage media. The steering committee decided to change the name of the program to better represent the truly multidisciplinary aspect of the management of information in industry.
Information Management is more comprehensive and more explicit than database management which typically is understood as the data stored in form of records in a computer. With multimedia, CAD, collaborative work, and other recent technological breakthroughs in communication and computers, the management of information is critical.
We decided to keep the word engineering in the name of the program since we are very much concerned with information that affects the engineer, whether involved in design or manufacture. However, this does not restrain the program to engineering data since information such as cost, schedule and other, affect the information and the design and manufacture.
This tenth anniversary symposium opens therefore under a new name, the Engineering Information Management Symposium. The papers presented at the conference deal with multidisciplinary aspects of information storage, retrieval, concurrent engineering, and the way companies deal with this often mammoth task. As in previous symposia, the focus is still to foster the exchange of information and present research that benefits industry.
Two tutorials also complement the symposium. They are: Process and Information Modeling: Applied to Business Process Re-engineering by Prof. Robert Fulton from the Georgia Institute of Technology and Dr. Ravi Rangan from SDRC, and Concurrent Engineering Fundamentals by Dr. Biren Prasad from General Motors.
I would like to thank the authors, the associate editors and paper reviewers for their efforts in writing and delivering the information, organizing the sessions, and reviewing the papers. Thanks are also due to Fred Goldfarb from ASME who makes sure everything is set up to facilitate communication and allow us to manage our own information.
