• Developed a cost-minimizing preventive maintenance scheduling model addressing maintenance frequency, utilizing mathematical modeling techniques.• Designed a non-linear scheduling model to allocate preventive maintenance operations triggered by time-based frequency over a planning horizon, while considering resource-capacity constraints.• Implemented scheduling mechanisms enabling the advancement or delay of maintenance compared to suggested frequency periods, with the objective of minimizing costs.• Demonstrated outstanding performance of the developed formulation, showcasing a significant average cost saving of 43% compared to alternative models with similar characteristics.• Investigated the relationship between maintenance frequency and tardiness cost, as well as utilization and schedule compliance, revealing important insights.• Explored scenarios where concurrent maintenance operations could yield time and cost benefits, and analyzed non-linear cost implications of tardiness.
