Arrange preventive maintenance over a specific time frame to reduce equipment failure rates and subsequent down time .This method is most effective when the service life of valves and other devices is known , because this can create and use better inspection schedules .Through preventive maintenance , the overall efficiency of the plant will increase , and the maintenance costs are far lower than the repair or replacement costs due to failure .Pre dic tive maintenance is condition - based and uses compu ter ized data and intelligent instruments to enable maintenance engineers to efficiently schedule maintenance times .This technology is used in many factories today because it can help improve equipment reliability , reduce maintenance costs and reduce down time by discovering defects before they fail .As the name implies , predic tive maintenance predicts the device condition by analyzing various information (such as maintenance history , design data , performance history , diagnostic information , and operation logs) .
