1. A system for diagnosis of electromechanical devices of at least one predefined type, the system comprising:

  • a communication unit that communicates with an actual device of the at least one predefined type;

    a unit that accesses a knowledge data set containing knowledge relating to properties of devices of the at least one predefined type;

    a unit that accesses a device data set containing parameters of the actual device, the parameters including actual error data indicating errors that occurred in an actual period;

    a unit that accesses a history data set containing historical data of the actual device, the historical data including at least one of historical error data relating to errors, performance data relating to performance analysis and remediation data relating to failure remediation that occurred before the actual period;

    a calculation unit that analyzes and combines data from at least one of the knowledge, device and history data sets for generating a prioritized item list indicative of remedial steps to be executed, the items relating to at least one of performance and failure of the actual device, and being prioritized according to priority rules; and

    a systematic error analysis unit connected to the calculation unit that systematically detects trends or patterns in the actual and historical error data,wherein the systematic error analysis unit is arranged for detecting at least one trend of the actual device by comparing relative error values calculated from the actual and historical error data, and the calculation unit is arranged for including a trend item in the prioritized item list when the at least one trend exceeds a predetermined threshold.
