Nissan Motor Deploys DELMIA Solutions
to Design and Validate Body, Assembly and Powertrain

DELMIA Manufacturing Hub data repository is key component for integration of
Product, Process and Resource (PPR) information

Auburn Hills, Mich., Oct 5, 2004 – Delmia Corp., a leading provider of digital manufacturing solutions, today announced that Nissan Motor Co., Ltd., a leading global car manufacturer, has selected DELMIA solutions, including V5 DPM Assembly™, V5 DPM Body-In-White™, V5 Robotics™ and Process Engineering™. Nissan is using this suite of DELMIA solutions to design and validate some key body in white, final assembly and powertrain manufacturing processes.

Auto makers’ vehicle development data have become large and diversified due to a variety of factors, including changing market needs, global disbursement of product development organizations and manufacturing sites, and production of increasing numbers of vehicle models and variants. Now more than ever, automotive manufacturers must manage, share and utilize data efficiently throughout the enterprise in order to drive innovation and reduce time to market.

To meet these obligations, Nissan decided to deploy DELMIA solutions for body in white, final assembly as well as particular powertrain processes. Nissan has implemented the DELMIA Manufacturing Hub, which integrates product, process and resource (PPR) information into a common data repository. This allows process planners, manufacturing engineers and resource engineer’s access to the latest real-time PPR data. Product designs, manufacturing processes and resource utilization, - including the set up of factories, lines, workcells, robot layouts and worker ergonomics - can all be validated in the digital environment prior to any actual production. In addition, Nissan is also using DELMIA solutions for serviceability evaluation and material handling processes.

“DELMIA offers Nissan end-to-end automotive process coverage solutions from preliminary process planning to detail validation”, said Mr. Nakajima, Senior Manager, Vehicle Planning and Strategy Department, Vehicle Production Engineering Division, Nissan Motor, Co., Ltd. “With DELMIA solutions, we are aiming to enable early validation of preparation in vehicle production.”

“Nissan’s continued investments in DELMIA’s technology and industry expertise demonstrate the value of our industry-proven digital manufacturing solutions in the global automotive market,” said Philippe Charlès, CEO, Delmia Corp. “This partnership between Nissan and DELMIA is truly a win-win relationship built on a common vision towards innovative car development processes.”

“We are honored that a global innovation pioneer like Nissan has selected DELMIA as a strategic partner, and we, along with our business partners, are fully committed to continuing our support of Nissan,” said Bertrand Saint-Martin, President, Delmia Japan, Ltd.

DELMIA and its business partners fully support the deployment of Nissan’s digital manufacturing project by defining new work flows, setting up the company’s IT infrastructure and providing integrations with Nissan legacy systems.

Nissan will make a presentation on its innovative new car development project using DELMIA at the DELMIA Asia Pacific User Conference 2004 on November 16th 2004 in Shinagawa, Tokyo, Japan.
