The survival signature was recently introduced to simplify quantification of reliability for systems and networks. It is based on the structure function, which expresses whether or not a system functions given the status of its components. In this paper, we show how a straightforward generalization of the structure function can provide a suitable tool for scenarios of uncertainty and indeterminacy about functioning of a system for the next task. We embed this generalization into the survival signature, leading to a more flexible tool for quantification of the system reliability and related measures of dependability.
