Le suivi des contrats de maintenance garantit la disponibilité des équipements critiques. L’automatisation permet de centraliser chaque contrat, de programmer les interventions, de recevoir des alertes sur les échéances et d’archiver tous les rapports d’intervention. Ce système limite les arrêts imprévus, optimise la maintenance préventive et prolonge la durée de vie des matériels.
