Cooperation is an efficiency factor in many activities like design, medecine or maintenance. Several researches try to optimize cooperation activity by using tools or algorithms designed to enhance human interaction. Few researches are made on conceptual cooperation modeling. However, industrials want to compare different algorithms, organizations or cooperation modes. It is also useful to represent these systems in order to simplify design operations. We proposed our cooperating systems modeling in our previous work [12]. This one provides a simulation approach to answer to this needs. In this paper, we present an application of our modeling principles on an existing e-maintenance system. This system is part of our work on the european PROTEUS project [ITEA 01011, http://www.proteus-iteaproject.com/]. By using these modeling principles, industrials should be able to represent and simulate their remote maintenance systems in order to optimize them.
