<P>PROBLEM TO BE SOLVED: To provide a system for monitoring the performance of complex electromechanical systems and determining the maintenance needs thereof in the absence of critical errors, thereby avoiding the uncertainty of predicting maintenance needs based upon system history. <P>SOLUTION: The system includes monitoring a plurality of predetermined system conditions, collecting monitored values of the plurality of predetermined system conditions over time, and calculating system maintenance needs from the collected monitored values. The system includes a print monitoring program 60 which collects monitored values from the plurality of monitor system conditions along with a time of occurrence for each monitored value over time and stores them in a database 62, and an aggregate error handling program 64 which calculates system maintenance needs in response to the recorded monitored values and the time of occurrence for each monitored value. <P>COPYRIGHT: (C)2010,JPO&INPIT |
