Distributionally Robust Design for Redundancy Allocation
INFORMS Journal on Computing, 2020In this paper, we consider a redundancy allocation problem for a series parallel system with uncertain component lifetimes that minimizes system costs while safeguarding system reliability over a given threshold level. We consider mixed redundancy strategies of cold standby and active redundancy with multiple types of components.

ACTIVE REDUNDANCY ALLOCATIONS IN SERIES SYSTEMS
Probability in the Engineering and Informational Sciences, 2011We consider the problem of optimally allocating one/two active spares in series systems. Lifetimes of different configurations are compared with respect to the reversed failure rate order, the failure rate order, the increasing concave order, and the stochastic precedence order.

Active Redundancy Allocation in Coherent Systems
Probability in the Engineering and Informational Sciences, 1988We introduce in this paper a new measure of component importance, called redundancy importance, in coherent systems. It is a measure of importance for the situation in which an active redundancy is to be made in a coherent system. This measure of component importance is compared with both the (Birnbaum) reliability importance and the structural ...

On redundancy allocations in systems
Journal of Applied Probability, 1994Allocation of a redundant component in a system in order to optimize, in some sense, the lifetime of the system is an important problem in reliability theory, having practical applications. Consider a series system consisting of two components (say C 1 and C 2), having independent random lifetimes X 1 and X

JBW Redundancy-Allocation Algorithm
IEEE Transactions on Reliability, 1985Summary: A very simple heuristic redundancy-allocation algorithm for serial- parallel configurations is presented which: 1. Yields near-optimal system reliability under multiple resource system constraints. 2. Economically achieves a given redundant system reliability goal. 3. Accommodates both linear and nonlinear resource complexity functions.

Reliability–redundancy allocation problem with cold-standby redundancy strategy
Simulation Modelling Practice and Theory, 2014Abstract This paper considers the mixed-integer non-linear optimization of reliability–redundancy allocation problem (RRAP) to determine simultaneous reliability and redundancy level of components. In the RRAP, it is necessary to create a trade-off between component reliabilities and the number of redundant components with the aim of maximizing ...

Decision on Redundancy Allocation
2015Redundancy allocation is a decision that involves assessing and choosing where to locate additional components or subassemblies, above the minimum required for an existing system to operate, in order to promote the system’s reliability. Specifically, the field of multi-objective redundancy allocation has received several contributions since the 1970s ...
