The key of successful industry is to satisfy the customer requirements at the perfect delay with improved quality and cheaper price. In this context, Digital Factory is known to test and validate the couple product-production system during the product development process, with the usage of production system simulations. Therefore, we can use an information system to integrate and manage all information related to product, process and simulation in this context. But with this huge amount of information, an actor of product development process may be confused about making a good decision at this particular stage. Thus, there is a lack of knowledge capitalization and sharing between product development process actors. On the basis of previous research works that contribute to the definition of a Digital Factory information system, we propose a new module, named KSim, dedicated to the capitalization and management of knowledge and experiences coming from previous projects in the Digital Factory context.
