Quantification of System Reliability using the Survival Signature

The survival signature [1] is a summary of the system structure function which is sufficient for several goals in system reliability quantification. In particular for larger systems which consist of just a few types of components, the survival signature may provide huge efficiency gains for the analysis. We will present an introductory overview of the survival signature. We will address its computation and approximation, its use for efficient simulation, and generalizations for phased-mission systems and for multiple systems (or system functions) sharing components. We will discuss ongoing research and further challenges.
