A maintenance free operating period (M-FOP) is defined as a period of time (or appropriate units) during which a system is both operational and is able to carry out its required function(s) without maintenance activities and without encountering failures. A failure free operating period (F-FOP) is defined as a period of time (or appropriate units) during which no failures, resulting in a loss of system functionality occur. Maintenance/failure free operating periods (M/F-FOPs) are measures of reliability and can be used to replace the traditional mean time between failure (MTBF) approach. M/F-FOPs has the potential to offer the user an increase in the application effectiveness and enhanced operational availability of a system.
Moving to M/F-FOP process increases application effectiveness and enhances the operational availability of a system during the M/F-FOP. The causes of failures are analyzed in the PoF approach, which is provided to the designers for effective system design. Thus M/F-FOP of a system can be obtained using PoF approach. Implementing a M/F-FOP process when designing a system provides a shift towards a scientific approach in preventing failures and caters to the need for an increase in operational availability.
