Patent Images
1. An apparatus for monitoring the maintenance of a plant equipped with various systems, the apparatus comprising:
- a screening module for defining the function of each of the systems and accordingly screening the systems;
a classifying module for determining the importance of each of the systems and accordingly classifying the systems so that the systems can be subjected to various levels of monitoring;
a performance criteria-setting module for setting performance criteria for each of the levels of monitoring;
an availability data module for recording the status and hours of the unavailability of each of the systems;
a reliability data module for determining whether any of the systems fails;
a real-time monitoring module for monitoring the availability data module and the reliability data module and determining whether any of availability and reliability limits is reached;
a performance-assessing module for receiving information from the real-time monitoring module, accordingly monitoring the trend of the function of each of the systems and correcting any ineffective activity of the maintenance; and
a special monitoring module for receiving information from the performance-assessing module, executing special monitoring on any of the systems if necessary and returning the system to the custody of the performance-assessing module if the system reaches the goals of performance again.
