Abstract
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 (PDP), with the usage of production system simulations; therefore we can use an information system like InfoSim 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 PDP may be confused to make a good decision at this particular stage. Thus, there is a lack of knowledge capitalization and sharing between PDP actors. In this research work, we propose a conceptual model dedicated to the management and capitalization of knowledge and experiences of previous projects in the context of Digital Factory.
