The "twin base modeling" for telemaintenance process

The remote maintenance of the industrial processes knows an important competitiveness with the technological advance which returns the performance of a machine accessible from any place in the world. The industrial processes become increasingly complex, this complexity makes only increase the overload of information and the risk of errors, which involves forcing an immense difficulty to supervise them by the human operator, and an important cost of the maintenance action. The development of a telemaintenance system offers to the industrialists and users a great flexibility in industrial activities control, it must support distant facilities to ensure the industrial plant performance and the quality of the operations. We can say that the operator or the technician will be able to work in a virtual operational environment. In this direction the approach by powerful multi agents systems with their characteristics in the resolution of problems tends to be widespread in all the fields of research in particular in those of remote maintenance. In front of the vastness of information, no genius can remember everything, nor to solve any problem. Thus a cooperative working group proves necessary even essential. However the capacities of problems resolution do not rest solely on the group knowledge, its experiment, but still depend on its capacities to make an effective search for an assistance of this working group. Within this framework of idea our modeling of the activities of a remote maintenance system is by choosing an interaction protocol between expert agents making it possible to ensure an efficient cooperation.
