The Digital Factory aims to provide simulation tools for the design of a product and its production system in parallel. However, the Digital Factory is under used in the industries because of the lack of organization and methodology supports, of the variety of simulation tools that compose it, and finally of the amount of data and information generated without tools or information management system suitable for this approach. In this work, we focus on this last point and we propose a tool of integration and information management for product / process simulations throughout the product lifecycle. This tool must be capable of integrating different business views (design, manufacturing, simulation), coming from different information systems.
