Multi-scale structuring of enterprise's knowledge Towards an ubiquitous virtual assistant

When the question about the "factory of the future" is discussed, it is often mentioned the use of innovative approach for knowledge acquisition and exploitation interfering in the different phases of the product lifecycle. Consequently, the use of innovative Knowledge Management Systems based on Information and Communications Technology (ICT) in the factory environment has become a must. Our research work will focus on the development of a "digital factory assistant" to help factory's actors in their daily tasks and in particular tasks that demand to make a decision.
