Optimizing bi-objective redundancy allocation problem with a mixed redundancy strategy
ISA Transactions, 2015Redundancy Allocation Problem (RAP) is a challenging subject which has attracted the attention of many authors. Generally, in the RAP there are two strategies for using the redundant components: active and standby. In this paper a new redundancy strategy, called mixed redundancy, is introduced and considered in a multi-objective optimization RAP ...

Redundancy allocation in distributed systems
2022Distributed systems, e.g., distributed/parallel computing and distributed storage systems, have become necessary for handling ever-increasing data storage and computing requirements. Distributed systems can significantly increase the job execution speed by employing multiple computing servers to work in parallel. However, the random frustrations of the

Redundant via allocation for layer partition-based redundant via insertion
2009 IEEE 8th International Conference on ASIC, 2009The occurrence of via defects increases due to the shrinking size in integrated circuit manufacturing. Redundant via insertion is an effective and recommended method to reduce the yield loss caused by via failures. In this paper, we introduce a redundant via allocation problem for layer partition-based model and solve it using genetic algorithm.

A method of redundancy allocation
Microelectronics Reliability, 1973A simple and new method is provided for allocating redundancies to various stages of a system, to maximize the system reliability under some given constraints. The approach suggested does not require tedious and long computations. The approach may be helpful to system designers to arrive at the solution quickly with little algebraic manipulation.

Optimal redundancy allocation in complex systems
Journal of Quality in Maintenance Engineering, 2010PurposeThis paper aims to focus on solving highly constrained redundancy optimization problems in binary complex systems.Design/methodology/approachThe proposed algorithm searches a possibly improved solution in thek‐neighborhood (k≥2) of the current best feasible solution, by adding one unit in a selected subsystem and eliminating one from some other ...

Redundant task-allocation in multicomputer systems
IEEE Transactions on Reliability, 1992Summary: This paper describes a simple yet effective method to improve multicomputer/multiprocessor system reliability via redundant allocation of tasks to computers (processors). Given any known (non-redundant) scheduling strategy, tasks are allocated to processors statically and redundantly using \(k\)-circular shifting (\(k\)CS) algorithm, so that ...

Fuzzy Random Redundancy Allocation Problems
2010Due to subjective judgement, imprecise human knowledge and perception in capturing statistical data, the real data of lifetimes in many systems are both random and fuzzy in nature. Based on the fuzzy random variables that are used to characterize the lifetimes, this paper studies the redundancy allocation problems to a fuzzy random parallel-series ...

Redundancy Allocation in Turbo-Equalizer Design
IEEE Transactions on Communications, 2005This paper considers properties of the extrinsic information transfer (EXIT) functions of turbo equalized intersymbol interference channels and finite-impulse response precoders. An analytic expression is derived for the maximum value of the EXIT function of the equalizer.

Reliability allocation with partial redundancy
Annual Reliability and Maintainability Symposium. 1991 Proceedings, 2002Concentration on the modeling of failure rates has produced a body of results only tangentially useful in the logistics modeling applications. The rate of occurrence of failures (ROCOF) is a more pertinent measure for such problems. This useful measure has been largely overlooked as a result of the relative rarity of redundancy.
