Today with new technologies and thanks to the generalization of connected sensors, we can access, for a given object, a plethora of information of different kinds in the form of a flow. The question arises of their use, their influence on each other and their synthesis to meet given objectives. For industrial equipment, it is essential to propose a strategy for evaluating energy consumption, a maintenance policy to be applied as well as a self-diagnosis to avoid a production stoppage and protect the environment. In the developments of Industry 4.0, data becomes more and more important but also complex.
They can contribute to decision support on the state of health of a product with a view to possible remanufacturing. This is where you have to make the right decision in a context of sustainable development. Concerning the use of the data thus classified for self-diagnosis, self-prognosis, it will be a question of developing methods of exploitation of the envelopes of normal operation and of evaluating the degree of criticality of the degradation compared to data real-time recorded.
The establishment of a Maintenance Workshop in a company greatly contributes to the minimization of inevitable maintenance costs. Beyond the initial investment, a maintenance workshop when it is well organized in terms of the layout of the various treatment and repair stations and the sizing of the spare parts storage areas, allows, thanks to the pooling of skills and means of minimizing the residence time of materials in the workshop. In addition, it allows the reuse of components in good working order. It is in this context that maintenance contributes greatly to sustainable development. Different axes will be dealt with during this plenary.
Professor at University of Grenoble
Zineb SIMEU-ABAZI is Professor at the Polytech Grenoble in the University Grenoble Alpes where she teaches control processing, Automation and Industrial Engineering, dependability and Industrial Maintenance. She holds a Ph.D. in Computer Science and Automation at the Institut National Polytechnique de Grenoble, INPG France on 1987 and an « Habilitation à Diriger des Recherches” » HDR in 1998, from Grenoble University, France.
She works on modelling, control and evaluation of dependability in the manufacturing systems. She is particularly interested in the on-line maintenance, diagnostic, recycling and performance evaluation fields. In relation to these topics she took scientific responsibility of French and International projects/groups on e-maintenance.
