The research of data mining in AHM technology based on association rule

In this paper we explore the key technique of the maintenance decision support system, which is a part of Aircraft Health Management (AHM) system. Based on the historical experience of airline maintenance data as the research object and the association rule mining by data mining, we attempt to find out the different maintenance measures to the same fault phenomena for maintenance person as the support for maintenance decision. At the same time, it defines the data source in association rule mining and the method of establishes the concept level of the aircraft system.
