Cold vs. hot standby mission operation cost minimization for 1-out-of-N systems
75
TL;DR: This paper first formulates and solves the SE-DSP problem for 1-out-of-N: G heterogeneous non-repairable standby systems and proposes a numerical method based on discrete approximation of time-to-failure distributions of the system elements.

The evolution of system reliability optimization
TL;DR: This paper considers the different types of system reliability optimization problems, including as examples, the redundancy allocation problem, the reliability allocation problem and the reliability-redundancy allocation problem (RRAP), and provides a flow of discussion and analysis on the evolution of the approaches for their solutions.

A novel strategy for redundant components in reliability--redundancy allocation problems
TL;DR: A new interpretation and formulation of the Reliability–Redundancy Allocation Problem (RRAP) is presented and it is demonstrated that solutions to this new problem provide distinct advantages compared with traditional approaches.

An exact algorithm for the reliability redundancy allocation problem
TL;DR: A new modeling/solution approach is proposed, in which the redundancy allocation problem is transformed into a multiple choice knapsack problem and solved to optimality via a branch and cut algorithm.

Orderings of coherent systems with randomized dependent components
TL;DR: This study provides sufficient conditions on the component’s lifetimes and on the random numbers of components chosen from the two stocks in order to improve the reliability of the whole system according to different stochastic orders.

Optimal Structure of Multi-State Systems With Uncovered Failures
TL;DR: A model of multi-state systems in which some groups of elements can be affected by uncovered failures that cause outages of the entire group shows that the maximal reliability of such systems can be achieved through a proper balance between two types of task parallelization.
Reliability Characteristics of $k$ -out-of- $n$ Warm Standby Systems
TL;DR: It is shown that the system reliability can be evaluated using robust algorithms within O(n-k+1) computational time and that the reliability of the warm standby system can be calculated using well-established numerical procedures that are available for the beta distribution.
A complex discrete warm standby system with loss of units
TL;DR: A redundant complex discrete system is modelled through phase type distributions and some measures of interest associated with the system, such as transition probabilities, availability and the conditional probability of failure are achieved in transient and stationary regimes.

TL;DR: An ant colony meta-heuristic optimization method is used to solve the redundancy allocation problem (RAP), and it is shown that the ant colony method performs with little variability over problem instance or random number seed.
