Snippet: Definition and description of dependent failures and common cause failures are provided. Several classifications (extrinsic/intrinsic, logic/lineage/dynamic, tangible/non-tangible) are proposed and the link between dependent and common cause failures is explained. Several examples from the real life are given to illustrate these definitions. The need for sharing the common cause failure data collection between several operators from several countries is highlighted. The beta-factor model and the
Document: Definition and description of dependent failures and common cause failures are provided. Several classifications (extrinsic/intrinsic, logic/lineage/dynamic, tangible/non-tangible) are proposed and the link between dependent and common cause failures is explained. Several examples from the real life are given to illustrate these definitions. The need for sharing the common cause failure data collection between several operators from several countries is highlighted. The beta-factor model and the shock model which can be implemented within systemic approaches (Boolean, Markov or Petri nets) and which belong to the most frequently used parametric models for common cause failure modelling are then described.
