Optimization Strategy and Positioning in Engineering Design

Satoshi Miyata, Advanced Technology Office, Engineous Japan Inc.

Nowadays optimization-based design approaches have been accepted by many general designers in manufacturing industries and spreading its application area day by day. Multi-objective optimization problem (MOOP) is such an active area of engineering optimization. Rapid development of application, however, also has been yielding many misunderstandings and abuses. (The history of optimization is known as iteration of boom and recession.) One of the reasons of the problems is recognition gap between algorithm developers, who has a little experience in design and practical users, who are not familiar with basis of optimization theories. Generally, when experts research and develop new algorithm, they must pay significant attentions on numerical behavior in laboratory, but less attention on how actual design problems are modeled to the simple optimization problem form. While industry users who uses the algorithms, in most cases, are not informed with the aforementioned situation and just informed with state-of-art features and excellent performances in the lab.
In the context, this paper tries to provide some view points that attempt to bridge the divisions between such theoretical person and business person, and be expected to contribute sustained growth of engineering optimization.

Heterogeneous Processing with Increased User Productivity

Mamoru Nakano, President, Cray Japan Inc.

Challenges in today's high performance computing market are stimulating changes in the way supercomputers are designed and this is one of the models that Cray refers to as adaptive supercomputing. This is a concept that transcends the idea of the heterogeneous supercomputing environment linking computers of differing architectural design rather than providing true processing heterogeneity and adaptability. We will explain Cray's efforts towards adaptive supercomputing while offering an explanation of the next-generation supercomputers that will serve as the first step in adaptive supercomputing to be announced by Cray at the end of 2006.

Introduction of modeFRONTIER and its Industrial Application Example in Occupant Safety Domain using MADYMO

Asahiko Otani, Integrated Simulation Technology Dept., CD-adapco Japan Co., Ltd.

Since modeFRONTIER has been introduced into industrial market in 2001 as the first commercial optimization tool for real Multi Objective Design Optimization(MODO), the MODO has become more popular and the importance and effectiveness of handling design optimization as Multi Objective Problem have been widely recognized among a lot of kinds of industrial companies all over the world. Accordingly, as the market demands for optimization tool have been escalating, modeFRONTIER has been answering them with state of the art multi objective optimization algorithms, easy to use graphical interface, various kinds of interfaces to application software, many useful post processing charts, advanced approximation algorithms for response surface modeling and unique robust design optimization capability: MORDO (Multi Objective Robust Design Optimization).
Primarily in this session, main features of modeFRONTIER will be introduced. Secondly, an application example done by FORD will be introduced. This example describes robust design optimization for Passengers Seat and Head Restraint in IIHS Rear Impact. The author announces that IIHS Rear Impact Rating achieved the target and productivity was improved very much.

[ITOCHU Techno-Solutions Corporation] Introduction of CAE2.0 system using iSIGHT-FD

Yuko Nishiura , Hirofumi Tanaka, Science & Engineering Systems Div. CAE Solution Dept., ITOCHU Techno-Solutions Corporation

Recently, consumers require that products have many performances.Each performance has many kinds of characteristic, and most relations between each characteristic are "Pareto".However, it is difficult to improve all characteristics at the same time.To solve these problems, products are often designed with optimization methods.Also, to improve the competitive strength of the product, it is forced to shorten the development period. iSIGHT-FD which is a software robot automates the operation of CAD/CAE which the engineer does.You can apply tools like optimization, DOE and DFSS techniques if you want. We CTC have solved many problems with many manufacturer partners.We present some solutions with iSIGHT-FD.
