Opportunistic Strategy for Maintenance Interventions Planning: A Case Study in a Wastewater Treatment Plant

Wastewater treatment plants (WWTPs) face two fundamental challenges: on the one hand, they must ensure an efficient application of preventive maintenance plans for their survival under competitive environments; and on the other hand, they must simultaneously comply with the requirements of reliabili...
