Application of AK-SYS method for time-dependent reliability analysis

Abstract: 

The aim of this paper is to propose an approach to address time-variant reliability problems using sys-
tem reliability methods. The remaining challenge in time-variant reliability is related to problems with
low failure probabilities, high dimensionality, and including costly-to-evaluate performance functions.
One of the main steps towards resolving time-dependent problems is to descretize the desired time in-
terval. This step creates a similarity between time-variant and system reliability problems. Therefore
efficient system reliability methods can be used to address time-variant reliability problems. AK-SYS
is an efficient reliability method for systems that can be employed for performance functions that are
expensive to evaluate. In this paper, application of this method for time-variant reliability problems is
investigated.
