Abstract

A system and method of servicing a group of similar types of equipment that maybe installed at geographically separated locations is described. The method makes use of error messages produced by the equipment and service requests received by a servicing center. Data mining techniques are used to establish error patterns associated with specific failure modes so that future error messages may be processed to determine if an identified failure mode has occurred. This will enable the efficient dispatch of spare parts and service personnel to the location where the failure has occurred.
