Today, fault trees are still created and maintained manually by experts. But there are various approaches for the automatic generation of fault trees. These procedures are very different and have been strongly influenced by their application domain. Therefore, no standard procedure exists yet. In order to define a standardized procedure, it is necessary to understand the generation process and to implement a pragmatic solution. In this work, we describe an approach to generate fault trees automatically by using automatically created component fault trees. The aims of this approach are to simplify the creation of fault trees and enable the continuous maintenance.
