A novel general reliability model optimization model based on mixed redundancy strategy is
proposed for k-out-of-n: G subsystems. In this model, the minimum required component for …

The reliability–redundancy allocation problem (RRAP) involves the selection of components
reliability and redundancy levels, with the aim of maximizing system reliability. Generally …

The existing reliability formulation regarding mixed and K-mixed strategies considers only
one component as the minimum number of required components for each subsystem. In this …

This paper innovatively proposes a new model of multi-type production system which can
process different types of production. The multi-type production system consists of several …

Ultra reliable life support is needed for environmental control and life support systems
(ECLSS) of space stations (SS) because provisioning of spare parts or a speedy crew …

Designing a reliable system under different working conditions is a challenging task for
system designers. This paper introduces different approaches to cope with the uncertainty of …

Satellite communication system holds a crucial role in modern society, so it is significant to
improve its reliability and stability. Optimizing reliability and designing redundancy become …

This paper proposes an MINLP model that represents the stochastic process of system
failures and repairs as a continuous-time Markov chain, based on which it optimizes the …

Opportunistic maintenance (OM) is a key solution to reduce the maintenance costs or/and to
improve the system dependability/performance. However, the existing OM models are …

The present work studies the effect of redundancies on the reliability of coherent systems
formed by modules. Different redundancies at components' level versus redundancies at …
