Abstract:
Predictive maintenance scheduling is an optimization problem aimed at defining the best activity sequence to minimize the expected cost over a time horizon. For very-large systems such as in experimental physics, maintenance optimization turns out to be very difficult owing to analytically intractable objective functions. In this paper, a meta-heuristic predictive maintenance algorithm based on the Generalized Extremal Optimization (GEO) is presented. With respect to state-of-the-art meta-heuristic techniques, the GEObased maintenance algorithm allows optimization procedure to be configured easily through only one parameter without a numerous population. Preliminary results of the algorithm performance validation on the liquid helium storage system of the Large Hadron Collider at CERN are reported.
