P R E F A C E

The emergence of new information technology has effected a dramatic change in the shipbuilding industry. ICCAS "97 Yokohama graphically revealed the current state of the art as well as the keen edge of technology.

The topics presented according to session organization comprise:

IT Projects in tlie Shiphuildiiig (Invited Papers) Case Report Initial Design Genetic Algorithm Infonnation Technolog Y CAD/CAM/CIM Hydrodynamic Design Robotics Robot Control EDI &. STEP Structural Design Virtual Reality Product Modelling Simulation Based Design Manufacture

Accuracy Management

Concurrent Engineering & Virtual Enterprise Expert System

The papers are published in the same sequence as the conference sessions. Altogether 81 papers, including three invited papers, from 18 countries, were selected from more than a hundred abstracts by the International Programme Committee. The contents of E D I & STEP, and Virtual Reality are much more specific than before, and Accuracy Management became a main stream in this field of research and practice. Also, new trends in Product Modelling have become apparent. Basically, these two volumes show us the path our industry should take.

We are happy to publish these papers and deeply appreciate the efforts o f t h e committee members, contributors and participants who led the conference to go on record as a success.

We also thank the Society of Naval Architects of Japan since this conference was held as a part of its centennial celebration.
