| Résumé: | The technological obsolescence of industrial systems is characterized by the
existence of challenger units possessing identical functionalities but with improved
performance. This paper aims to define a new approach that makes it possible to obtain the
optimal number of obsolete industrial systems which should be replaced by new-type units.
This approach presents a new point of view compared with previous works available in the
literature. The main idea and the originality of our approach is that we apply a genetic
algorithm (GA) by considering the failure frequency, the influence of the
environment/safety factors of the old-type systems and the purchase/implementation cost of
the new-type units. These parameters are introduced in order to optimize this type of
replacement in the context of engineering |
