This is preventive maintenance according to technical condition, based on data obtained by monitoring performance and/or parameters.

Operational data usage

The PATRIOT® 3.0 maintenance management system enables the automatic collection and evaluation of operational data of maintained equipment. It includes a SCADA system optionally supplemented with diagnostics even for dislocated sites. Most often, information from production control systems can be used directly for this purpose and if data is not available standard sensing units can be connected. The sensed operational data is stored in a database where it is used for analytical methods of time-to-malfunction calculations in predictive maintenance. In case of difficulties in implementing the SCADA system its operation can be replaced by batch data from the on-site diagnostics with off-line transmission of the measured data to the maintenance management system.

Operational data or data from diagnostic system records are used to predict future conditions and events. Based on these data; calculations of key performance indicators (KPIs) are performed to quantify the overall performance. The technical KPIs that are measured include MTBF, MTTR and the reliability and availability indicators OEE and TEEP. The operational data is also used to predict the lifespan of machines, groups and individual components. They are also used as input information for spare parts inventory management.
