Reliability and redundancy allocation analysis applied to a nuclear protection system
Brazilian Journal of Radiation Sciences, 2021 Brazil is constructing with national technology two small nuclear reactors for propulsion and for radioisotope production with thermal power levels between 20 and 50 MW. These nuclear reactors fit more in the class of small modular reactors (SMR) than in

Efficient optimization of multi-objective redundancy allocation problems in series-parallel systems [PDF]
Decision Science Letters, 2017 Reliability issues are most important types of optimization problems and they are used in communication, transportation and electrical systems. This paper presents two mathematical models to solve the k-out-of-n redundancy problem where there are two ...

OPTIMIZED REDUNDANCY ALLOCATION FOR ELECTRONIC EQUIPMENT [PDF]
Engineering Optimization, 1988 This paper describes a methodology for optimizing the temperature dependent reliability of electronic equipment using active redundancy, while satisfying an area constraint. The process consists of transforming the unreliability objective function by adding to it a suitable penalty term so as to force the optimum solution to an “almost integer” value ...

Innovating Aircraft Repair Processes: The Role of Digitalization in Sustainability
Advanced Engineering Materials, EarlyView.This research explores how digitalization—by storing detailed non‐destructive testing data in structured DICONDE databases and creating a standard data model of the component—innovates aviation maintenance and repair processes. Coupled with a developed state‐based simulation model, it enables data‐driven, sustainable repair strategies that reduce waste,

Standby Redundancy Allocations in Series and Parallel Systems [PDF]
Journal of Applied Probability, 2011 To enhance the performance of a system, a common practice employed by reliability engineers is to use redundant components in the system. In this paper we compare lifetimes of series (parallel) systems arising out of different allocations of one or two standby redundancies.
