Data of machine breakdowns and costs related to maintenance, components, and the interval time of failure for each machine were collected. To develop a preventive maintenance system, the interval of component replacement must be determined. The minimum cost model is attained by finding the right interval time. The result of this research shows that by implementing proposed maintenance schedule the machine reliability has 45% increase and maintenance cost decreases by 48%.
