This study presents a framework for machine maintenance planning based on the integration of risk-based maintenance (RBM) and Cost of Unreliability (COUR) techniques. Using a reliability-based approach, RBM is essentially a method for determining a plan or program of maintenance activities based on the risk of failure and the consequences of component failures. COUR is the total cost of the situation caused by a failure in reliability, including the costs associated with a poor reliability program and poor maintenance. As a practical example, we provide a core builder machine maintenance plan as a case study. In order to reduce the risk value, the maintenance time intervals for critical components of the core builder machine have been shortened, specifically for the Heater component from 24 days to 6 days, the Roll component from 48 days to 13 days, and the Conveyor component from 48 days to 23 days. As a result, the company’s maintenance costs for the core builder machine decreased from Rp 39,953,220 to Rp 8,143,768.
