Error cause automatic evaluation method for operating device, involves outputting empirical value for default risk of operating device by display unit, where valve is determined by multiplication of different characteristics

摘要

The method involves capturing errors during an operation of an operating device by sensors and devices for detection of signals, which are assigned to function units and evaluated by determining a characteristic for likelihood of occurrence of one error cause. Another characteristic for denotation of the error cause of an error leading to a failure is determined. A third characteristic for likelihood of detection of the error cause is determined. An empirical value for a default risk of the device is output by a display unit, where the valve is determined by multiplication of characteristics.
