Infinite-Dimensional System Signature: System Signature Under the Repairable Principle

TL;DR

This paper introduces a novel method for calculating the system signature and reliability of repairable parallel and serial systems with infinite components, filling a gap in existing reliability analysis literature.

Contribution

It develops a new approach to create system signatures for repairable systems, considering infinite components and the repair principle, which was not addressed in prior studies.

Findings

Successfully calculated system signatures under repairable principle

Demonstrated the method on parallel and serial systems with two components

Extended the concept of system signatures to infinite components in repairable systems

Abstract

Investigation of the reliability of technical systems is one of the application areas of stochastic processes. The reliability of a technical system is based on two main elements. The first is the connection type of the system, and the second is the distribution of the working times of the components consisting of the system. In this study, system signatures and their reliability will be calculated under the repairable principle of parallel and serial systems consisting of two components. Although there are a limited number of studies in the literature for repairable systems, there is no study on creating the signature of repairable systems. In technical systems where there is no repair principle, although the system signature has limited components, the technical systems working under the repairable principle, have infinite components of the system signature. While creating the system signature, the probability that the working time of the component that is in the state of the system failure is greater than the repair time was defined as the parameter {\xi}. In the application part of the study, under the principle of repair, the system signature, and the reliability of the system were be successfully calculated.
